## **Engineering Data** 

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. 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. 

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

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

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

## 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. 

## 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. 

## Dynamic Response 

The power supply output voltage will remains within ±5% of its steady state value, when subjected to a dynamic load from 0% to 100%.

**TECHNICAL DATASHEET** 

## **PMC Panel Mount Power Supply** 12V 36W 1 Phase / PMC-12V035W1A☐ 

## Overload & Overcurrent Protections (Auto-Recovery) 

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. 

## Overvoltage Protection (Auto-Recovery) 

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”. 

## 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 than 100%, 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 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.
