The 24 VDC to 48 VDC, 60 W Isolated Converters provide regulated 48 VDC power suitable for instrumentation and controls operating in a battery powered system. Power from a battery or other source at 24 VDC nominal (9 to 60 VDC) is converted to a 48 VDC output regulated to 3% and 1.3 Amp continuous current. Input and output isolation is provided. The isolated converters are designed with extremely rugged surge and transient suppression in addition to sustained over/under voltage protection as well as inrush current control. For operation under the most harsh and demanding conditions, the units are fully sealed and enclosed to protect against moisture, shock, and vibration. With 60 Watts of output power, the DC-DC converters have an efficiency rated at 89%.
