These six new rectifiers have a 450-550W output power range. With batteries, the rectifiers have pre-set output voltages of 13.6V, 27.2V or 54.4V. Without batteries, the rectifiers have output voltages of 12, 24, and 48V. Active power factor correction is standard with the universal input range of 85 to 264VAC. Two of them can be connected together for higher-power applications. They run in temperatures from -20 to 70C. They have control and monitoring features plus a +5V standby output. Green LEDs indicate and ac and dc power. All models meet relevant safety standards.
