GENERATOR
ANTI-CONDENSATION
HEATER AH1H
Appropriate when the generator set is to be sited in
a low ambient and/or high humidity environment,
the heater maintains the AC generator at a suitable
temperature to prevent winding corrosion due
to condensation.
The heater itself is powered by a 110/120 volt
(VAC 120) or 208/240 volt (VAC 240) AC auxiliary
supply protected by a fuse inside the main control
panel. When the generator set is not running the
heater is automatically connected to the AC supply
through a power relay mounted in the control
panel. Upon receiving a start signal the AC supply
is automatically disconnected by the power relay
and automatically reconnected when the start
signal is removed and the engine has stopped.
