HFR RANGE
One-way, high frequency and energy recovery electronic control HFR 1D
Nominal operating voltage: 12-24-36V
Allowed operating range: 85-125%
Operating frequency: 18Khz
Acceleration and speed are under control!
The unidirectional high frequency electronic contol unit with energy recovery type HFR1D has been added to the newest range. Conceived for permanent magnete motors, this equipment complies with the newest security provisions for the application on EC-vehicles and is produced in a wide power range (from 60 A up to 150 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 whose max. value is fixed by the recovery braking adjusting device.
