The Protect 8 thyristor-controlled rectifier is designed to provide a highly reliable power supply and battery charging capability as a standalone device or as part of the Protect 8 industrial UPS series. The Protect 8 rectifier is built from independent Protect 8 building blocks, suitable for charging nickel-cadmium or lead acid batteries while supplying DC loads or the inverter of the UPS. It can also be used without batteries as a direct power supply. The UL version of the Protect 8 rectifier is compliant with UL 1012/ UL 1778 and with relevant IEEE/ANSI/NEMA standards. The Protect 8 UL is designed in Germany; engineered and assembled in the United-States.
