AX081801K 48Vdc/24Vdc Step Down Converter

The DC-DC Converter provides regulated 26 Vdc/24Vdc power suitable for solenoids, relays and other electrical systems. For operation under the most harsh and demanding conditions, the IP67 rated unit protects against moisture, shock and vibration. Power from a battery or other source of 48 Vdc is converted to a 24-26 Vdc output. The unit has a high current output capability of 13 Amps. The device manages heat dissipation and requires no forced cooling systems. Short-circuit and reverse polarity protections 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 330 Watts of output power, the DC-DC Converter provides proprietary dual-phase topology for a high efficiency of >95%.

Applications:

Designed to interface between 48V batteries and 26V/24V electrical systems such as solenoids, relays and other electrical systems found on mobile equipment, lift trucks and buses.
