5.13. Over Temperature Protection (OTP)
The OTP circuit shuts down the Power Supply before any 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-Start or Auto-Restart mode.
a) Safe-Start mode: In Safe-Start mode, the Power Supply stays Off after the Over-
Temperature condition has been removed. The display continues to show “OTP” and
the ALARM LED continues to blink. To reset the OTP circuit, press the OUT button
(or send “OUT ON” command via the serial port).
b) Auto-Restart mode:
In Auto-Restart mode, the Power Supply recovers to its last
setting automatically when the Over-Temperature condition is removed.
5.14. Last Setting Memory
The Power Supply is equipped with Last Setting Memory, which stores specific Power
Supply parameters at each AC turn-off sequence.
Stored Parameters:
•
OUT On or Off
•
Output voltage setting (PV setting)
•
Output current limit (PC setting)
•
OVP level
•
UVL level
•
FOLD setting
•
Start-up mode (Safe or Auto-Restart)
•
Remote/Local (Local Lockout will return to Remote mode)
•
Address setting (RS-232/RS-485, LAN, IEEE or USB)
•
