Overexcitation rectifiers with integral motor current detection

These overexcitation rectifiers with built-in current sensor are ideal for installation in the junction boxes of motors, brakes and solenoids.
As switching operations are determined by the motor current, these rectifiers provide braking times that would normally only be possible with additional DC side switching.
Dynamic requirements in terms of quick motor stopping can be satisfied by using this type of brake rectifier without necessitating additional lines and external contacts for DC side brake switching. The rectifier and current sensor combination provides electronic DC side switching directly within the rectifier.
Owing to the integral overexcitation, these rectifiers also ensure rapid brake release times and thus minimal wear during motor start-up as well as reduced motor starting current and energy consumption of the brake. The housings are designed for installation in the motor junction box. They are compatible with Kendrion rectifiers 32 0732x.., 32 1732x.., 32 4730x.., 32 6730x.. and 32 7730x.
