Comprehensive alarm system - provides complete status on charger and battery. Heavy-gauge aluminum housing - gives modern appearance and corrosion protection. Standard input and output breakers - reduces the need for spare fuses. Proven SENS quality - means years of trouble-free service. Charger/Rectifier Product Highlights SENS DC/Telecom chargers/rectifiers supply reliable DC power to telecommunications, process control and other equipment that requires a well filtered source. The DC/Telecom ensures the highest possible reliability of a battery-backed DC power system. The DC/Telecom automatically eliminates the No. 1 cause of premature failure in maintenance-free batteries -- improper charging. The filtered output and SENS' temperature-compensated control circuitry extends battery life, eliminates over- and undercharging and reduces risk of thermal runaway. SENS DC/Telecom chargers are designed for service anywhere in the world. Standard units operate on either 50 or 60 Hz; input voltage is field-selectable for either 115 or 230 volts.
