-
with mains supply (110/120V, 220/230V or 240V / 50Hz or 60Hz), output power of
50VA
-
via an internal battery (for mobile use), output power approx. 20VA
-
via external battery (12V to max. 24VDC)

Designed for continuous operation
In all operating modes the unit is designed for continuous operation. The output power of
50VA is only reached with:
-
mains operation or external battery operation (with 24VDC)
-
optimum
adjustment.
During mains and battery charging operation, please observe that:
The voltage setting of the mains voltage socket must correspond to the local mains voltage!
Carry out battery test
The integrated battery (=lead-acid battery) is protected by a low discharge protection circuit
causing the TG20/50 unit to be switched off at a discharge voltage of 10.5V.
Before each mobile use and battery operation, please check the battery state of charge.
Check state of charge using control button
Charge battery

is charged by the built in charger (with an overload protection).
-
General
battery charging time
should be at least
12 to 14 hours!
The TG20/50 unit can also be used during the battery charging process. That means, the
integrated battery is also charged during each mains operation.
Do not store lead acid battery in a discharged state. Charge the battery all 14 days during the
