BL series rectifier deviceDetailed product description：

Use
The BL (K) series rectifier device is mainly used to match the YEJ series electromagnetic brake three-phase asynchronous motor. It rectifies AC power into DC power through the rectifier device, providing DC power for the brake. This device has input and output protection circuits, suitable for high-frequency operation of inductive devices. This device belongs to the sealed type and is suitable for the working environment specified by YEJ motor standards. It can be directly installed in the junction box of the motor. This device can also be used in DC power supply and control circuits with similar conditions. The wiring of the rectifier power input terminal is not allowed to work with a frequency converter. Otherwise, it will affect the normal engagement of the brake, and in severe cases, even burn out the brake and motor.

Classification of rectifiers
1. The BL series rectifier is a regular rectifier. When controlling the switch on the AC side of the rectifier, the magnetic field attenuation is slow because the generated voltage during motor deceleration is added to the motor terminals, resulting in a very long delay in response time. When controlling the switch on the DC side of the rectifier, the energy of the magnetic field is absorbed by the rectifier, resulting in a faster delayed response time than when switching on the AC side.
2. The BLK series rectifier is a fast braking rectifier. When controlling the switch on the AC side of the rectifier, rapid response of the brake can be achieved.

Appearance and wiring

When the BL series rectifier needs to cooperate with fast braking, connect the "yellow" and "green" wires to the normally open point of the contactor. When the brake motor allows for slower braking speed, the "yellow" and "green" wires can be directly short circuited.
