48V DC Uninterrupted Power SupplyThe A48/15 rectifier individually delivers 825 W of output power to telecommunication equipment such as digital loop carriers and mobile communication systems. The A48/15 applies state-of-the-art technologies such as a full-wave bridge rectifier, pulse width modulation (PWM) and power factor compensation technology. The rectifier also guarantees reduction of energy losses, a high power factor (0.99 or above), 91% efficiency at 230 V, and an operating frequency of 50 kHz!
