## **Functions**
## โ **Graph illustrating the Start-up Time, Rise Time, and Hold-up Time**
## Start-up Time
The time required for the output voltage to reach 90% of its final steady state set value, after the input voltage is applied.
## Rise Time
The time required for the output voltage to change from 10% to 90% of its final steady state set value.
## Hold-up Time
Time between the collapse of the AC input voltage, and the output falling to 95% of its steady state set value.
## Inrush Current
Inrush current is the peak, instantaneous, input current measured and, occurs when the input voltage is first applied. For AC input voltages, the maximum peak value of inrush current will occur during the first half cycle of the applied AC voltage. This peak value decreases exponentially during subsequent cycles of AC voltage.
## Dynamic Response
The power supply output voltage will remains within ยฑ5% of its steady state value, when subjected to a dynamic load from 0 to 100% of its rated current.

## Power Boost
Power Boost is the reserve power available constantly that allows reliable startup to support sudden and short spike of loads with high inrush current typically during turn on to remove the need of more expensive higher rated power supply unit. After the output has reached its steady state set value, the power supply can support surge loads with a higher short-term power demand up to 150% of maximum rated load (IO Max), for a maximum duration of 5 seconds. The Power Boost is also available to repeatedly basis with according to the condition of an average (R.M.S) output power shall not exceed continuous operating condition or refer to duty cycle calculation below.

It is not recommended to prolong the duration of Power Boost to be longer than the specified duty cycle calculation, this may cause damage to the PSU.
## External Input Protection Device
The unit is protected at the L pin, with an internal fuse that cannot be replaced. The power supply has been tested and approved on 20A (UL) and 16A (IEC) branch circuits without additional protection device. An external protection device is only required if the supplying branch has an ampacity greater than above. Thus, if an external protective device is necessary, or, utilized, please refer a minimum value of 8A B- or 4A C- characteristic breaker.

## Overload & Overcurrent Protections (Auto-Recovery)
The power supplyโs Overload (OLP) and Overcurrent (OCP) Protections will be activated when output current (IO) exceeds its specification as defined on Page 3 under โProtectionsโ. In such occurrence, the output voltage (VO) will start to droop and once the power supply has reached its maximum power limit, the protection is activated and the power supply will go into โHiccup modeโ (AutoRecovery). The power supply will recover once the fault condition of the OLP and OCP is removed and IO is back within the specifications.
## Overvoltage Protection (Auto-Recovery)
The power supplyโs overvoltage circuit will be activated when its internal feedback circuit fails. The output voltage shall not exceed its specifications defined on Page 3 under โProtectionsโ.
## Over Temperature Protection (Auto-Recovery)
It is not recommended to prolong the duration of IO when it is less than OLP/OCP point, but greater than100%, since it may cause damage to the PSU.
As described in load de-rating section, the power supply also has Over Temperature Protection (OTP). In the event of a higher operating temperature at 100% load, the power supply will run into OTP when the operating temperature is beyond what is recommended in the de-rating graph. When activated, the output voltage will go into bouncing mode until the temperature drops to its normal operating temperature as recommended in the de-rating graph.
## Short Circuit Protection (Auto-Recovery)
The power supplyโs output OLP/OCP function also provides protection against short circuits. When a short circuit is applied, the output current will operate in โHiccup modeโ, as shown in the illustration in the OLP/OCP section on this page. The power supply will return to normal operation after the short circuit is removed.

## Operating Mode
## ๏ฎ **Redundant Operation**
In order to ensure proper redundant operation for the power supply unit (PSU), the output voltage difference between the two units must be kept at 0.45~0.50V for 24V supplies. Follow simple steps given below to set them up for the redundant operation:
## **Step 1.**
Measure output voltage of PSU 1 and PSU 2. If PSU 1 is the master unit, then VO of PSU 1 must be higher than PSU 2. In order to set the output voltage, individually connect the power supply to 50% of rated load at any line voltage from 85-264Vac, and set the PSU 1 and PSU 2 output voltage.
## **Step 2.**
Connect the power supply units PSU 1 and PSU 2 to Vin 1 & Vin 2, respectively, of the DRR-20N (or 20A) module shown on the diagram on the right.
**The Signal GND in the DRR module is for the built-in LED and DC OK signals. The Output GND terminals from the two PSUโs do not need to be connected to the Signal GND terminal.
## **Step 3.**
Connect the system load from Vout. Please note that output voltage Vout from DRR module will be = VO (output voltage of power supply) โ Vdrop* (in DRR module).
## **Fig. 4 Redundant Operation Connection Diagram**
*Vdrop will vary from 0.60V to 0.90V (Typical 0.65V) depending on the load current and surrounding air temperature.
## ๏ฎ **Parallel Operation**
The power supply units (PSUs) can also be used for parallel operation in order to increase the output power. The difference in output voltage between the two units must be kept to within 25mV of each other. This difference must be verified with the same output load connected independently to each unit.
Parameters such as EMI, inrush current, leakage current, PARD, start up time will be different from those on the datasheet, when two units are connected in parallel. The user will need to verify that any differences will still allow the two power supplies connected in parallel will work properly in their product/application.

Delta's CliQ-II can use on 2 of 3 phase system. Please refer to the following step.
## **Step 1.**
The input voltage applied from Line to Neutral is below the maximum rated input. The input voltage shall be below 240Vac +10%.
## **Step 2.**
The external protector is needed on N (Neutral) input line to secure a safety. N line does not have internal fuse protection. An appropriate fuse or circuit breaker should be connected in series with N input line connection like the following.

## Conformal Coating
## **The Protective Coating Technology**
Delta Electronics Group has designed the perfect dipping technique which penetrates everywhere including under device, and prevents leakage. The conformal coating dipping can be applied to PCBAs or circuit board. The coating preserves the performance of precision electronic primarily by preventing ionizable contaminants such as salt from reaching circuit nodes, where the material slumps around sharp edges. This can be a problem especially in highly conversing atmosphere.
