BENNING World Class Power Solutions THYROTRONIC rectifier range for stationary back up power supply General The protection of electrical load against power failure is often carried out by battery backed up DC power supplies, providing electrical energy to important loads during mains supply, as well as during mains failure. Battery backed up DC power supplies have, over several decades proved extremely reliable and very economical power supplies. The reliability of a battery backed up DC power supply is defined by the quality of the battery used, as well as the reliable operation of the rectifier....

BENNING World Class Power Solutions THYROTRONIC rectifier range for multi-purpose use Operation Lead-acid and nickel-cadmium batteries achieve optimum service life when remaining on float, in a charged condition. The charger floats the battery in a charged state and also supplies the load with power. In the event of mains power failure the battery will then supply the load its required power. This is called "parallel operation" (see fig. 2). With substantially discharged batteries, the rectifier unit at first operates in the I-branch of the IU-characteristic line, whereby the charging current...

BENNING World Class Power Solutions safe, reliable, powerful Rectifier series Thyrotronic The Thyrotronic series consists mainly of a thyristor-controlled power unit and a microprocessor-controlled monitoring and control unit. The following main components are included: • mains input with contactor • mains transformer with separate windings • fully controlled 6 pulse three phase bridge with semi conductor protection fuse (working primarily as battery inverse polarity protection) • smoothing chokes and capacitor bank to reduce ripple • control unit with digital setpoint setting • digital monitoring...

BENNING World Class Power Solutions THYROTRONIC comprehensive alarm and monitoring concept Functions of the signalling and monitoring unit: In the rectifiers of the Thyrotronic range a very large monitoring concept with the following functions is included as standard: Mains monitoring In case of a mains failure, an electronic regulator block is initiated and the LED and the "mains failure relay" will be activated. If the mains voltage returns the unit is automatically switched on after a set time. Charger output monitoring The charger output monitoring is a current-dependent low voltage monitoring...
