Low power three-phase motor, Energy consumption brake special bridge rectifier,
[Origin China] [Brand TORQ] [brand new]
Rectifier mode: bridge rectifier
1)Recommended input voltage(Rectifier input voltage): 100Vac/110Vac/200Vac/220Vac/230Vac/240Vac/380Vac/440Vac
Apply to 440Vac and below power supply.
Maximum allowable input voltage: 470Vac.
The reason for the use of low voltage is suggested:
You can choose low-power current limiting resistor,Can reduce costs and save energy.
2)For 380V, 400V, 415V, 440V three-phase motors:
It can be used for energy consumption braking of 15KW (20HP) motors.It can also be used for 18.5KW (25HP) braking,The time interval for more than 30 minutes.
For 200V, 220V, 230V, 240V three-phase motors:
It can be used for energy consumption braking of 3.7KW (5HP) motors,The time interval for more than 30 minutes.
For 100V, 110V, 120V three-phase motors:
It can be used for energy consumption braking of 2.2KW (3HP) motors,The time interval for more than 30 minutes.
3)The input of this device can use a transformer to reduce the voltage,Or a proper resistance is connected in series(or series resistors on the output side).
The output of the device needs to be connected to the motor terminal by a set of contactor contacts.
A protection circuit is arranged inside the device, which can withstand large current shock and sudden change of voltage without damage, but the short-circuit output terminal is not allowed during operation.
4）Ambient temperature: 0-45 degrees C
Maximum allowable input voltage: AC470V
Allows long term output current: IO=DC160A(The heat sink is fully cooled and the temperature of the heat sink is not higher than 60 degrees C)
Output characteristic (current time): I2t =40000A2seconds (t=1 sec)
Ambient humidity: no limit
5)Current limiting resistor, we can send the goods together, the price is calculated separately.
We are manufacturer,We accept large orders, too.
