Uncontrollable three-phase rectifiers of the V-TPED series

Rectifiers of the V-TPED series are intended for food of power and operational chains of a direct current, and also for food of chains of dynamic braking of asynchronous electric motors.

Rectifiers have the following types of protection:

· at short circuits at the weekend conclusions;

· at breakdown of power diodes;

· at the overload exceeding specified in technical documentation;

· at emergence of retension at shutdowns of a nenagruzhennogovypryamitel.

Rectifiers have the following types of the alarm system:

· about presence of the feeding tension on an entrance;

· about the included and disconnected condition of switching devices;

· about control of isolation of both poles of a power chain.

Rectifiers on currents 1600 A, 2000 A, 3200 A, 4000 A have a microprocessor control system with non-volatile memory.

The microprocessor control system provides control of a condition of diodes: break, breakdown, deterioration in parameters, normal state.

Protection against a transformer overheat is provided.
