2RU HIGH-DENSITY HOT-SWAP RECTIFIERS

PRODUCE UP TO 100 AMPERES AT 48VDC OR 200 AMPERES AT 24VDC

Coral Springs, Florida- UNIPOWER Telecom's new Ranger RRP Series hot-swap rectifier modules each produce 25A at 54.4VDC (48V version) or 50A at 27.2VDC (24V version). In a three-unit, 19-inch shelf they produce 75A or 150A, respectively; in a four-unit, 23-inch shelf they produce 100A or 200A, respectively. The complete power system is only 2RU high (3.5 inches).

The rectifier modules feature a wide 85-264VAC universal input range,  input power factor correction, automatic load sharing between modules, and integral output ORing diodes for hot swapping. The output can be adjusted over a 45 to 58V or 22.5 to 29V range by means of a front-panel voltage adjustment potentiometer or by a remote DC input control signal from a controller. Other features include a Class B EMI input filter, 87% efficiency, output overvoltage and current limiting protection, and front panel LED status indicators.
