BGE 1.5 Rectifier for Motor Brake Applications
One way rectifier, with current relay for cut-off in the DC circuit and electronic switching, for use with electromagnetic brake systems for electric motors. This dependable one-way rectifier features a voltage rating 150 – 500 VAC, a holding current of 1.6 Ihmax in Amps, type BGE 1.5, and is red in colour.
The BGE brake rectifier is a half-wave rectifier with over-voltage protection elements and electronic control for reducing the brake release reaction times. The brake operation is improved by the BGE rectifier as it releases the brake initially by super-magnetisation and then holds the stationary disc securely with reduced magnetisation. Due to the exceedingly reduced brake release reaction time the brake is released before the motor can build up torque and begin to rotate.
Minimum wear with maximum service life and excellent switching ability are the primary features of the brake system. In the continuous released state, the current losses are reduced to the minimum making the thermal loading of the brake very low. BGE series rectifier units are ideally mounted in the motor terminal box but can also be used for switch cabinet installation.
The use of the BGE Brake Rectifier is ideal if short brake release reaction times are required, high starting frequencies are encountered, and a high ambient temperature is present, or the brake is in the continuous released state while the motor is at rest or operating at low speeds. When several brakes are connected in parallel to the same brake rectifier, the total of all the operating currents must not exceed the rated current of the brake control.
