## **6 High-voltage test (HIPOT)** 

This protection class II power supply is subject to the Low Voltage Directive and is factory tested. During the HIPOT test (high-voltage test), the insulation between the input circuit and output circuit is tested for the prescribed electric strength values, for example. The test voltage in the highvoltage range is applied at the input and output terminal blocks of the power supply. The operating voltage used in normal operation is a lot lower than the test voltage used. 

## **6.3 High-voltage dielectric test performed by the customer** 

Apart from routine and type tests to guarantee electrical safety, the end user does not have to perform another highvoltage test on the power supply as an individual component. According to EN 60204-1 (Safety of machinery - Electrical equipment of machines) the power supply can be disconnected during the high-voltage test and only installed once the high-voltage test has been completed. 

High-voltage tests up to 2 kV AC / 2.8 kV DC can be performed as described. 

The test voltage should rise and fall in ramp form. The relevant rise and fall time of the ramp should be at least two seconds. 

## **6.1 High-voltage dielectric test (dielectric strength test)** 

In order to protect the user, power supplies (as electric components with a direct connection to potentially hazardous voltages) are subject to more stringent safety requirements. For this reason, permanent safe electrical isolation between the hazardous input voltage and the touch-proof output voltage as safety extra-low voltage (SELV) must always be ensured. 

In order to ensure permanent safe isolation of the AC input circuit and DC output circuit, high-voltage testing is performed as part of the safety approval process (type test) and manufacturing (routine test). 

## **6.2 High-voltage dielectric test during the manufacturing process** 

During the manufacturing process for the power supply, a high-voltage test is performed as part of the dielectric test in accordance with the specifications of IEC/UL/EN 61010-1. The high-voltage test is performed with a test voltage of at least 3 kV AC / 4.2 kV DC or higher. Routine manufacturing tests are inspected regularly by a certification body.

**QUINT4-SYS-PS/1AC/24DC/2.5/SC** 

## **6.3.1 Performing high-voltage testing** 

If high-voltage testing of the control cabinet or the power supply as a stand-alone component is planned during final inspection and testing, the following features must be observed. 

- The power supply wiring must be implemented as shown in the wiring diagram. 

- The maximum permissible test voltages must not be exceeded. 

Avoid unnecessary loading or damage to the power supply due to excessive test voltages. 

- For the relevant applicable test voltages and insulation distances, refer to the corresponding table (see technical data: electric strength of the insulation section).

## **9 Device connection terminal blocks** 

The AC input and DC output terminal blocks on the front of the power supply feature screw connection technology. 

For the necessary connection parameters for the connection terminal blocks, refer to the technical data section. 

## **9.1 Input** 

The power supply is operated on single-phase AC systems or two outer conductors of three-phase systems. The power supply is connected on the primary side via the INPUT L/N connection terminal blocks. 

The power supply is approved for connection to TN, TT, and IT power grids with a maximum phase-to-phase voltage of 240 V AC.

## **9.3 Output** 

By default, the power supply is pre-set to a nominal output voltage of 24 V DC. 

The output voltage is adjusted using the potentiometer. 

## **9.4 Protection of the secondary side** 

The power supply is electronically short-circuit-proof and no-load-proof. In the event of an error, the output voltage is limited 

If sufficiently long connecting cables are used, fuse protection does not have to be provided for each individual load. 

If each load is protected separately with its own protective device, the selective shutdown in the event of a fault enables the system to remain operational.

## **10 Output characteristic curves** 

The U/I output characteristic curve is optimized for the following applications: 

- When supplying loads with high switch-on currents, such as motors. The dynamic boost of the power supply supplies up to 200% of the nominal power for 5 s. This ensures that sufficient reserve energy is available; overdimensioning of the power supply is not necessary. 

- For system extension. With the static boost, up to 125% of the nominal output power is available for a sustained period (up to 40°C). 

- For fast energy storage charging (e.g., of batteries) to supply a wide range of loads. The power supply operates in the nominal operating range. Energy supply to the load is ensured.

## **11 Boost currents** 

The power supply provides the static boost (IStat. Boost) for a sustained load supply or the time-limited dynamic boost (IDyn. Boost). 

## **11.1 Static Boost** 

For system expansion purposes, the sustained static boost (IStat. Boost) supports the load supply with up to 125 % of the nominal current of the power supply. The static boost is available at an ambient temperature of up to 40 °C.

## **12 Signaling** 

Two LEDs and a floating signal contact are available for signaling and function monitoring of the power supply. Use the rotary selector to select the required functional monitoring. The available options are monitoring of the output voltage (DC OK) or alerting when the output power threshold (POut > PThr) is exceeded. 

## **12.1 Rotary selector switch in position DC OK:** 

In this switch position, the output voltage (UOut) is monitored. If the DC OK threshold is exceeded (UOut > 0.9 x USet), the green DC OK LED lights up. Additionally, the signal output (SIG) is switched to "closed." If the output voltage drops below the DC OK threshold value (UOut < 0.9 x USet), the DC OK LED flashes. The signal output is "open." 

## **12.2 Rotary selector switch in position >50 %, >75 % or boost >100 %:** 

In each of these switch positions the output power (POut) is monitored. When the defined threshold is exceeded, the yellow LED (POut > PThr) lights up and the signal output (SIG) "opens."

## **13 Operating modes** 

Depending on the intended use, the power supply can be run in series or parallel operation. 

## **13.2 Parallel operation** 

You can connect several power supplies in parallel in order to increase the power or to supply the loads redundantly. 

Figure 23 Schematic diagram in parallel operation 

## **13.1 Series operation** 

To double the output voltage, connect two power supplies in series. Only use power supplies with the same performance class and configuration for series operation. If two 24 V DC power supplies are connected in series, an output voltage of 48 V DC is available to supply the loads.

Observe the following points when carrying out parallel connection: 

1. Use power supplies of the same type and performance class 

2. Setting the same output voltages 

3. Using the same cable cross sections for wiring 

4. Using the same cable lengths for the DC convergence point 

5. Operating power supplies in the same temperature environment 

6. When three or more power supplies are connected in parallel, each output must be protected (e.g., with circuit breakers or decoupling modules)

## **13.2.1 Redundancy operation** 

Redundant circuits are suitable for supplying systems and system parts which place particularly high demands on operational reliability. 

If energy is to be supplied to the load with 1+1 redundancy, two power supplies of the same type and performance class must be used. In the event of an error, it must be ensured that one of the power supplies is able to provide the total required power for the load. This means that in redundancy mode, two 2.5 A power supplies supply a load with a nominal current of 2.5 A, for example. During normal operation of the power supplies, each power supply therefore supplies 1.25 A. 

Always use cables with the same cross sections and lengths when wiring the power supplies on the DC output side. 

A redundancy module can be used to 100% decouple two power supplies from one another and to ensure the supply. A distinction is made here between passive and active redundancy modules. Optimum decoupling with simultaneous monitoring and minimal power dissipation can be achieved with the UNO DIODE redundancy module.

## **13.2.2 Increased power** 

When n power supplies are connected in parallel, the output current is increased to n x IN. Parallel connection for increased power is used when extending existing systems. If the individual power supply does not cover the current consumption of the most powerful load, parallel connection of power supplies is recommended. 

When three or more power supplies are connected in parallel, each output must be protected separately, e.g., by a circuit breaker or decoupling module such as UNO DIODE or STEP DIODE.

Certain specifications apply in redundancy operation with regard to the configuration of the keepout areas. In redundancy operation, the power supplies are operated with maximum half the nominal power. The keepout areas are therefore reduced. 

The following conditions must be met for 1+1 and n+1 redundancy operation of the power supplies in conjunction with a UNO DIODE redundancy module. 

Only use power supplies with the same performance class and configuration for parallel connection. 

Using the signaling settings, you can monitor whether both power supplies are being operated with ≤ half the nominal load. In the case of system extension, an overload is prevented if one of the power supplies fails.

## **14 Derating** 

The QUINT POWER power supply runs in nominal operation without any limitations. For operation outside the nominal range, the following points should be observed depending on the type of use. 

## **14.1 Ambient temperature** 

When operating the power supply at an ambient temperature of > 60 °C, a power derating of 2.5 %/K should be observed. Up to an ambient temperature of 40 °C, the power supply can take power from the static boost for a sustained period. In the 40 °C to 60 °C temperature range, the power supply can output more than the nominal power for a sustained period.

## **14.2 Installation height** 

The power supply can be operated at an installation height of up to 2000 m without any limitations. Different data applies for installation locations above 2000 m due to the differing air pressure and the reduced convection cooling associated with this (see technical data section). The data provided is based on the results of pressure chamber testing performed by an accredited test laboratory.

## **14.3 Position-dependent derating** 

The fanless convection-cooled power supply can be snapped onto all DIN rails according to EN 60715. 

The power supply should be mounted horizontally for heat dissipation reasons (AC connection terminal blocks facing downward). Please observe the derating for any mounting other than the normal mounting position. Reduce the output power based on the prevailing ambient temperature. 

The recommended output power for different mounting positions and ambient temperatures can be found in the characteristic curves below. 

Exceeding these values will reduce the service life of the power supply.
