Overload detection
Usually, the operating mode for the expected use of this DC power
supply is CV (Constant Voltage regulation).
The process this device is used for should never be affected by a short-
circuit.
Overload detection rules:
- the actual output current reaches its set point
- the actual output voltage goes down to a defined voltage drop
threshold within a short amount of time ( max. 50 ms)
The overload function integrated in the device will react in this way:
The DC power supply will switch to BLOCKING mode immediately
(DC output OFF).
The voltage drop threshold can be set from 1 % to 99 %.
The recommended value is 20-40 %.
If an overload occurs:
The display shows:
“OVERLOAD”
and a short “beep” is heard.
The LED in OFF key is flashing (indication for BLOCKING mode).
The LED in CLR key is flashing.
Press CLR key for alarm reset.
Press the ON key to restart the DC power supply.
