4QHF 2D HIGH FREQUENCY ELECTRONIC CONTROL UNIT WITH ENERGY
RECOVERY
The bidirectional high frequency
electronic control unit with energy
recovery and aided by microprocessor
type 4QHF 2D has been added to the
newest range of products manu-
factured by ELEKTROSISTEM.
Conceived for permanent magnete
motors and realized in compliance with
the most recent security provisions for
the application on EC-vehicles, it is
produced in a wide power range (from
45 A up to 140 A). The acceleration
adjusting device allows the vehicle to
gradually and regularly reach the
maximum speed.
The current limiter enables the operator
to adjust the max. current supplied to
the motor.
This control unit is provided with a
variable regenerative braking that can
be adjusted by the operator according to
his needs and acts during the vehicle’s
deceleration, reverse and by pedal release.
MAIN TECHNICAL FEATURES
– Control unit aided by microprocessor.
– Operation parameters adjustable through a
programming display or by PC.
– Slow starting through adjustable acceleration slope.
– Settable limiter of the max. current supplied to the
motor.
– Proportional action thermal limiter.
– Recovery braking system activated during
deceleration, by pedal release and in reverse.
– Settable limiter of the max. braking current.
– Control system by a 5K potentiometer connected to
3 wires.
– Control system by a potentiometer connected to 2
wires with adjusting angle on request.
– Total protection against battery polarity inversion
thanks to an internal line relay.
– Intervention of the safety block in case of short
circuit of the Mos units.
– Intervention of the safety block in case of
potentiometer breakdown.
– Intervention of the safety block when, turning the
key, the potentiometer is not on 0 and disabling by
resetting the potentiometer to 0.
