PSU18K: 72VDC to 12VDC 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 IP65 rated unit is fully encapsulated 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 VA of output power, the DC-DC Converter features proprietary dual-phase topology for a high efficiency of >93%.
