MINI DC-UPS
Setting the output voltage
In the normal mode, the output voltage of the device conforms
to the setting on the potentiometer (10 V DC ... 16 V DC). If the
supply voltage fails, the buffer mode is activated without any
interruption and the output voltage is supplied by the
rechargeable battery module. The output voltage is now
directly dependent on the battery voltage and is U
BAT
- 0.5 V.
An alarm signal is triggered if the output voltage drops below
10.2 V in the buffer mode. If the output voltage drops to 9.6 V
due to a completely discharged rechargeable battery module,
the device switches off and remains switched off. The device
switches on automatically only after reconnecting the power
supply. The device is electronically protected against short-
circuits and no-load operation.
Buffer time setting
The buffer mode might be terminated after the preset time or
due to an external shutdown. If the device is to be shut down
after a specific time has elapsed, the time can be set via the
selector switch on the front of the device. The device can be
switched on in the buffer mode again after reconnecting the
power supply.
