OVER TEMPERATURE PROTECTION (OTP) 

The OTP circuit shuts down the power supply before the internal components can exceed their safe 

internal operating temperature. When an OTP shutdown occurs, the display shows "OTP" and the 

ALARM LED blinks. Resetting the OTP circuit can be automatic (non-latched) or manual (latched) 

depending on the Safe or Automatic restart mode. 

 

1. Safe start mode: In Safe start mode, the power supply stays off after the over temperature 

condition has been removed. The display continue to shows "OTP" and the ALARM LED continues 

to blink. To reset the OTP circuit, press OUTPUT button (or send OUT ON command via the serial 

port). 

 

2. Auto-restart mode: In Auto-restart mode, the power supply recovers to it's last setting 

automatically when the over temperature condition is removed. 

 

5.13.

 

LAST SETTING MEMORY 

The power supply is equipped with Last Setting Memory, which stores power supply parameters at 

each AC turn-off sequence. 

 

STOREDPARAMETERS: 

1. Output voltage setting 

2. Output current setting 

3 .OVP level 

4. UVL level 

5. FOLD setting 

6. Start-up mode (Safe or Auto-restart) 

7. Remote/Local (If the last setting was Local Lockout, the supply will return to Remote mode) 

8. Address setting 

9. Baud rate 

10. Locked /Unlocked front panel 

(Items 7, 8, 9 are related to Remote digital control operation and explained in chapter 6) 

 

5.14.

 

SERIES OPERATION 

Power supplies of the SAME MODEL can be connected in series to obtain increased output voltage. 

Split connection of the power supplies gives positive and negative output voltage. 

 

 

 

 

 

CAUTION 

Do not connect power supplies from different manufacturers in series or in 

parallel.
