DC to DC Converter - 48V DC, 21.0 Amps, 1000 Watts,
4 Fuse Protected Outputs, Rack Mounting Version
Valiant’s DC to DC converter may be used to convert 90V DC ~ 373V DC Input Voltage to 48V DC output voltage. It may be also used to convert 85V AC-264V AC, 47Hz-63Hz AC Mains Input Voltage to 48V DC Output Voltage. The DC to DC converter is designed for telecom applications requiring stable DC voltage with low EMI and EMC interference. This is an external converter power supply which is available in 19 inch rack mount version, with four fuse protected outputs.
