Victron Orion 24/12-70A DC-DC Converter w/Binding Posts - IP20

The Victron Orion 24/12-70A DC-DC Converter with Binding Posts (IP20) is an industrial-grade power regulation system engineered for dual-voltage auxiliary charging and multi-bank electrical architectures. Whether you're building a custom auxiliary power system for overlanding rigs, mobile workshops, auxiliary battery banks, or professional service vehicles, this converter steps down 24V primary systems to stable 12V output with serious current capacity. It's designed for users who demand reliable voltage conversion without the complexity or failure modes of older buck-converter designs—think marine electrics, RV builds, heavy equipment auxiliary systems, and commercial fleet applications where redundancy matters.

This converter delivers continuous 70-amp output at 12V from a 24V input, making it capable of supporting simultaneous aux loads—winches, compressors, lighting, inverters, and charge controllers—without voltage sag or thermal throttling under sustained draw. The binding post terminals eliminate the need for proprietary connectors, allowing field-friendly wire termination and replacement without special crimpers. Remote on-off capability via low-power switch or engine control signal means you integrate seamlessly into existing kill-switch logic, ignition systems, or battery isolation relays. The IP20 rating protects against accidental finger contact and light dust ingress, though you should still house it in a weatherproof enclosure for underhood or saltwater environments. Victron Energy's multi-stage MOSFET topology and thermal management ensure minimal voltage ripple and longevity even in harsh duty cycles.

This unit is ideal for mechanics and fabricators upgrading fleet vehicles, restoring vintage truck electrical systems, or installing auxiliary power in expedition builds where 12V auxiliary loads must remain isolated from the main 24V charging circuit. Installation is straightforward: mount it near the primary battery (within 2 meters for signal integrity), run 24V input directly from the primary battery through an appropriate fuse, and connect the 12V output to your auxiliary bank or load distribution block. The compact 5 x 4 x 9-inch footprint fits neatly under seats, in battery boxes, or against firewall-mounted enclosures, and at 2.5 lbs it adds minimal weight penalty to your electrical architecture. Verify your 24V source can sustain 70A continuous draw; undersized alternators or weak batteries will limit real-world output but the converter will protect itself through thermal shutdown.
