PSU17K 72Vdc to 24Vdc Converter

The DC-DC Converter provides clean 24 Vdc power suitable for 24V solenoids, relays and other electrical systems. For operation under the most harsh and demanding conditions, the IP65 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 72 Vdc is converted to a 24 Vdc output regulated to 0.5%. The unit has a high current output capability of 13 Amp nominal (18 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 315 Watts of output power, the DC-DC Converter features proprietary dual-phase topology for a high efficiency of >95%.

Applications:
