SD Series
EPC SD Series rectifiers provide pure and regulated DC power for load, charging of Lead-Acid and Nicel-Cadmium batteries. SD series rectifers are used for very wide range of DC power applications such as power plants, telecommunication, power generation and distribution, traction, emergency lighting, automation systems and petrochemical plants.
SD Series Rectifiers are equipped with thyristors, which are used in
Semiconductor Controller Rectifier technology. Phase control and regulation are made by microprocessor controled eletronic boards. SD series has also output voltage regulation features with automatic current limiting.
SD Series rectifiers are flexible for different applications. Optional N+1 paralleling redundancy can be obtained by paralleling diodes. By adding
optional load circuit and current limiting unit, SD Series rectifier can be used as DC UPS, which provides DC power to load from battery, when the AC input is not available. When the AC input is recovered, rectifier will feed your DC load and charge your batteries. A load circuit for this purpose can be build by diode drop blocks or by a DC/DC converter, depending on requirements of the customer.
