Product Description

These DC to DC Converter power supplies are ideally suited for use with mobile 12/13.8 VDC equipment. Both Isolated and Non-Isolated models are available. The design technology emphasizes high efficiency, tight regulation and low ripple/noise. To meet individual peak power requirements, models support peak currents up to 25% above nominal. All models have built-in protection features including output current limiting, overvoltage protection, internal fuse protection, and over temperature shutdown. Isolated models include a crowbar on the output to prevent damage. These units integrate seamlessly with standard 12/13.8 VDC equipment. Screw-type terminal connections are used which are easily accessible and ensure a safe and reliable installation.

This DC to DC Converter (EDMO# A4812-24) has 30-56 VDC input voltage, 13.8 VDC output voltage, 18 A continuous current, and 24 A peak current.

Features

  • Input voltage range: 22 to 72Vdc, depending upon model
  • Handles up to an extra 25% peak current during peak power events
  • Built-in protections: Overvoltage, overcurrent and short-circuit protections with crowbar on Non-Isolated models
