APB Series

APB devices are single-half-wave rectifiers with an input supply of 100-500 Vac; they can therefore replace several rectifiers with limited input dynamics. The devices are equipped with a circuit to ensure a decisive excitation (opening of the brake), as when switched on it supplies the brake with two half-waves for a few hundred milliseconds. After this excitation time (inrush), the brake is energised with one half-wave, reducing current consumption. Input and output are protected against overvoltage peaks.
The housing is completely new, small in size and the input and output are with terminal block.
A switch can be inserted between terminals 3 and 4 to de-energize the brake, improving de-energizing times. The circuit is housed in the enclosure and resined for better protection.

The value of the protection fuse (F), must be understood as a device that the customer provides in the rectifier power supply circuit, as it is not present inside the rectifier itself.
