PSU18K DC-DC Converter

The DC-DC Converter provides clean power suitable for 12VDC electrical systems used in telecommunications and mobile equipment/vehicle applications. For operation under the most harsh and demanding conditions, the IP67 rated unit is fully sealed and potted in an enclosure to protect against moisture, shock and vibration. Power from a battery or other source of 72VDC is converted to a 12 VDC output regulated to 0.5%. The unit has a high current output capability of 15 Amp nominal (20 Amp peak). The device manages heat dissipation and requires no forced cooling systems. Short circuit and reverse polarity protection are provided.

The compact unit is designed with extremely rugged surge and transient suppression in addition to sustained over/under voltage protection. With a nameplate rating of 180 Watts of output power, the DC-DC Converter features proprietary dualphase topology for a high efficiency of >93%.


Designed to interface between 72V batteries and 12V electrical systems such as 12V solenoids, relays and other electrical systems.
