De-rating VS surrounding air temperature 

## **Note** 

1. Power supply components may degrade, or be damaged, when the power supply is continuously used outside the shaded region, refer to the graph shown in Fig. 1. 

2. If the output capacity is not reduced when the surrounding air temperature > 50°C, the device may run into Over Temperature Protection. When activated, the output voltage will go into bouncing mode and will recover when the surrounding air temperature is lowered or the load is reduced as far as necessary to keep the device in working condition. 

3. If the device has to be mounted in any other orientation, please do not hesitate to contact **info@deltapsu.com** for more details. 

**Fig. 1 De-rating for Vertical and Horizontal Mounting Orientation > 50°C de-rate power by 2.5% / °C** 

4. In order for the device to function in the manner intended, it is also necessary to keep a safety distance of 20mm with adjacent units while the device is in operation. 

5. Depending on the surrounding air temperature and output load delivered by the power supply, the device housing can be very hot!

## Safety Instructions 

- To ensure sufficient convection cooling, always maintain a safety distance of > 20mm from all ventilated surfaces while the device is in operation. 

- The device is not recommended to be placed on low thermal conductive surface, for example, plastics. 

- Note that the enclosure of the device can become very hot depending on the ambient temperature and load of the power supply. Do not touch the device while it is in operation or immediately after power is turned OFF. Risk of burning! 

- Do not touch the terminals while power is being supplied. Risk of electric shock. 

- Prevent any foreign metal, particles or conductors to enter the device through the openings during installation. It can cause: - - Electric shock; Safety Hazard; Fire; Product failure 

- Warning: When connecting the device, secure Earth connection before connecting L and N. When disconnecting the device, remove L and N connections before removing the Earth connection. 

## **Functions** 

## ■ **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 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 set value. 

## Hold-up Time 

Hold up time is the time when the AC input collapses and output voltage retains regulation for a certain period of time. The time required for the output to reach 95% of its set value, after the input voltage is removed.

**TECHNICAL DATASHEET** 

## **PMC Panel Mount Power Supply** 24V 150W 1 Phase / PMC-24V150W1AX 

## Inrush Current 

Inrush Current is the first surge current seen on the input side when AC input is applied to the power supply. It is the first pulse captured; see a typical picture for the inrush current as seen in the power supply. 

## Overload & Overcurrent Protections 

The power supply’s Overload (OLP) and Over current (OCP) Protections will be activated when output current exceeds 120% of IO (Max load). In such occurrence, the 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 “Hiccup mode” (Auto-Recovery). The power supply will recover once the fault condition of the OLP and OCP is removed and IO is back within the specifications. 

## Dynamic Response 

The power supply output voltage will remains within ±5% of its steady state value, when subjected to a dynamic load from 5% to 100% of its rated current. 

- **50% duty cycle / 5Hz to 1KHz** 

Additionally, if the IO is < 120% but > 100% for a prolong period of time (depending on the load), the Over Temperature Protection (OTP) will be activated due to high temperature on critical components. The power supply will then go into “Hiccup mode” until power supply cool down. 

## Over Temperature Protection 

As mentioned above, the power supply also has Over Temperature Protection (OTP). This is activated when the overload condition persists for an extended duration and the output current is below the overload trigger point but > 100% load. In the event of a higher operating condition at 100% load, the power supply will run into OTP when the surrounding air temperature is > 75°C. When activated, the output voltage will go into bouncing mode until the operating surrounding temperature drops to 50°C or output capacity is reduced as recommended in the de-rating graph. 

## Short Circuit Protection 

The power supply’s output OLP/OCP function also provides protection against short circuits. When a short circuit is applied, the output current will operate in “Hiccup mode”, 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. 

## Overvoltage Protection 

The power supply’s overvoltage circuit will be activated when its internal feedback circuit fails. The output voltage shall not exceed its specifications defined on Page 3 under “Protections”.

## Operating Mode 

##  **Redundancy Operation** 

In order to ensure proper redundancy operation for the power supply unit (PSU), ensure that the output voltage difference between the two units is kept at 0.45~0.50V for 24V supplies. Follow simple steps given below to verify: 

## **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, connect the power supply to 50% load and set the PSU 1 and PSU 2 output voltage. 

## **Step 2.** 

**Fig. 3    Redundancy / Parallel Operation Connection Diagram** 

Connect the right DRR module, 20A as per the system requirement to the power supply units PSU 1 and PSU 2 at Vin 1 & Vin 2 respectively. 

## **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) – Vdrop* (in DRR module). 

##  **Parallel Operation** 

These DRR modules can also be used for Parallel function in order to increase the output power by N+1 (e.g. 2.5A + 2.5A = 5A or 2.5A + 2.5A + 2.5A = 7.5A) or current sharing, and thus increasing the power supply and system reliability. Though the PMC-24V150W1AX is not designed for current sharing, a good current sharing between two power supplies can be achieved by following simple steps as below (Refer to Fig. 3 for the Connection Diagram). 

## **Step 1.** 

Set output load condition for both supplies at 50% and measure the output voltages. 

## **Step 3.** 

Connect PSU 1 and PSU 2 with the DRR-20A module and measure at Vin 1 & Vin 2 to verify the voltage difference. Ensure the voltages are within ±25mV. 

## **Step 2.** 

Adjust output voltages to the same level or within ±25mV difference. 

## **Step 4.** 

Output voltage from DRR module Vout will be = VO (output voltage of power supply) – Vdrop* (in DRR module). 

## ***Vdrop will vary from 0.60V to 0.90V (Typical 0.65V) depending on the load current and surrounding air temperature.**
