19.2. External Supply
The VM30-H can be supplied externally via a socket type Binder 711 (5 pins, female). The
supply voltage range is 8 to 12 VDC with a current consumption below 200 mA. The voltage
source must be able to supply a peak current of 1 A in the moment after switching on the
VM30-H. The power supply input is protected against false polarization.
Operation with external supply is indicated as “Ext.” instead of the battery indicator.
Charging the internal batteries by an external supply voltage is not possible.
