Power: 30kw.
Voltage: 400V.
Purpose: high frequency braking resistor.
The braking ability provided by the braking capacity is larger than that provided by the external braking resistor.
Can also be connected without built-in brake transistor inverter.
Three types of discharge resistors are available.
Please select according to the required braking torque.
"Power: 30kw.
Voltage: 200V.
Brake resistor, a kind of ripple resistance, is mainly used in the mechanical system of the inverter to control the speed of the motor,
Help the motor to be converted into heat energy due to the regenerative power of the motor.
Braking unit principle: the brake unit is composed of a high power transistor GTR and its driving circuit MITSUBISHI FR-BU2-H30K.
Its function is to link the discharge current braking resistor capacitor voltage or not in the range of the time consumed and the DC part "overpressure",
Need to add external braking components, in order to speed up the speed of the consumption of renewable energy
FR-BU2-H30K "MITSUBISHI inverter FR-A720 series.
