DESCRIPTION
The DKG-190 is a high-tech product designed to
decrease operating engine hours of gensets used
in telecommunication systems.
The unit brings considerable economies to genset
run-hours, fuel consumption and service cost.
In simple telecom systems, gensets run during
mains failure periods. Thus the genset run hour is
equal to the sum of mains failure hours.
The DKG-190 feeds the existing genset control
unit with the AC voltage that it generates
internally and prevents the engine from running
when not necessary. It can be adapted to any
brand and model of genset control unit.
When the mains is off, the DKG-190 continues to
feed the genset controller with AC voltage and
monitors the battery voltage. When the battery
voltage falls below the preprogrammed level, then
it cuts the AC voltage and causes the genset to
run.
The genset runtime is adjusted on the DKG-190.
When this timer is expired, the unit sends again
the AC voltage to the genset controller causing
the genset to stop. The genset stays in rest until
batteries are discharged again.
When the mains is restored, the genset stops
regardless of the battery charge status.
The unit measures and displays precisely battery,
genset and mains voltages.
The AC voltage generated by the unit is a pure
sinus with adjustable voltage and frequency.
These features are obtained thanks to the high
voltage PWM control and PID loop.
The unit can be virtually adapted to any genset
controller thanks to its adjustable parameters.
