||Output voltage can be adjusted within above range by V-ADJ. variable resistance<br>inside of the power supply. When output voltage exceeds the range, the power supply<br>will be in failure or get into over voltage protection mode. To avoid the case that the<br>output voltage is higher than rated voltage, output current should be used under<br>rated current.|||||

## 1.4. Protection 

|**Short Circuit**|Hiccup mode, it will recover automatically after fault condition is removed|
|---|---|
|**Over Voltage**|Over Voltage protection value 16V|
||(1) When output voltage exceeds above over voltage protection value or reversal<br>voltage occurs, the protection will be started and the output voltage will be cut off in<br>order to protect the power supply;<br>(2) The power supply will recover after the power is turned on again|
|**Over Current**|Over Current protection value 4A|
||(1) When output voltage exceeds above over current protection value, the protection<br>will be started and the output voltage will be cut off in order to protect the power<br>supply;<br>(2) The power supply unit will recover automatically after the fault condition is<br>removed.|
|**Over**<br>**Temperature**|Over Temp. protection value: 100 ± 10ºC|
||(1) When the ambient temperature exceeds above our temperature protection value,<br>the protection will be started and the output voltage will be cut off in order to protect<br>the power supply;<br>(2) The power supply unit will recover after the power is turned on again.|

## 3 **Applications and Maintenance** 

- 3.1. Series Operation 

Series Operation can be connected as shown: 

Load current should be less than the current value of the product with the lowest output current specified at the product specification with the Power Supply at series connection. 

**Ref.** IS.AC12VDC2.5ADIN 

**9** 

3.2. Parallel Operation 

Do not connect the power supplies as follows: 

Parallel operation should be composed with the same products, while the connection shoud be as shown as “Parallel operation C”; 

2. In Parallel operation C, current capacity cannot be increased, while it should be used for backup only. Moreover, diode that is to be added during parallel operation should be selected after considering it’s voltage drop, output voltage and current capacity.

3.3. Din Rail Mounting 

Hang part A on the top of the Rail as shown below, then push into B direction to fix it on the DIN Rail. 

Remember to leave a minimum of 25mm between both PSU or between the PSU and another device located inside the cabinet. Forced air cooling makes protection against heat better.
