## **For example  (24V model) :** 

Vin = 200Vac       Duty_max = 5% 

P av= P rated = 750W P pk= 1500W t�≤ 5 sec 5 sec T ≧ 5% ≧ 100sec P npk ≤ T PavT-tt P pk 

P npk[≤] 710W 

Note: When the output voltage is adjusted to the upper limit, the peak power is 150% rated power.

## **3.Remote Sense** 

The remote sensing compensates voltage drop on the load wiring up to 0.3Vdc. 

## **4.DC_OK signal** 

DC_OK is a collector shorted signal. It is used by an optocoupler in the power supply which indicates the output status of the power supply as exhibited below. 

|PSU Vo Status|Photo transistor|
|---|---|
|POWER ON|Conduct(Low impedance)|
|POWER OFF|Open(High impedance)|



Optocoupler Rating(max.) 15Vdc/10mA resistive load
