PSU4K: 24V to 48V DC Converter

The DC-DC Converter provides clean 48VDC power suitable for instrumentation and control networks or process equipment. For operation under the most harsh and demanding conditions, the unit is sealed and enclosed to protect against moisture, shock and vibration. Power from a battery or other source in the range of 20-30Vdc is converted to a 48Vdc output regulated to 1% and 3 Amps continuous current. Input and output isolation is provided. The unit is designed with extremely rugged surge and transient suppression in addition to sustained over/under voltage protection. With a nameplate rating of 144 Watts of output power, the DC-DC Converter has an efficiency rated at >90%.
