Victron Energy ORI241220260 | Orion IP67 24/12-20A (240W)

Victron Energy Orion IP67 24/12-20A Fully Encapsulated. Pre-Cabled. Built for Where Others Won't Go.

Product Overview

The Victron Energy Orion IP67 24/12-20A (ORI241220260) is a compact, fully encapsulated DC-DC step-down converter rated at 20 amps and 240 watts continuous, converting a 24V DC source to a regulated 12V DC output. Unlike conventional converter units housed in open-frame or vented enclosures, the ORI241220260 is constructed from cast aluminium with electronics moulded in resin completely sealed against water, oil, dirt, shock, and ignition hazards with no external enclosure required.

What makes this unit stand out in practical installations is the combination of its IP67 encapsulation, extra-long 1.8-metre input and output cables, and a wide 15–40V input range. The pre-fitted cables eliminate the need for intermediate connections in the majority of installs an important reliability advantage in demanding environments where every additional junction is a potential failure point. The wide input range handles voltage fluctuations from a partially discharged 24V bank through surge conditions from other loads on the same circuit, maintaining stable 12V output throughout. Built-in overheating protection means the unit can be installed in confined, high-temperature locations machine rooms, engine bays, and underbonnet spaces without thermal cutout concerns under normal operating conditions.

Features & Benefits

• Completely Encapsulated Construction — Cast aluminium housing with resin-moulded internal electronics. Water, oil, and dirt cannot penetrate the unit. Shockproof and ignition-protected as standard — no separate enclosure, no IP-rated cabinet, no additional cost or complexity. This is the converter you specify when the environment is genuinely hostile.
• IP67 Weatherproof Rating — Fully dustproof (IP6x) and protected against water immersion between 15cm and 1 metre depth (IPx7). Suitable for direct mounting in bilges, underbonnet compartments, underfloor chassis locations, marine bulkheads, and outdoor plant equipment — locations where a standard IP20 converter would fail or require a protective housing.
• Ignition Protected — Safe for installation in environments where flammable vapours may be present — petrol engine bays, fuel storage areas, and marine bilges with petrol engines. A critical compliance and safety specification often overlooked in converter selection.
• 1.8-Metre Pre-Fitted Input and Output Cables — Factory-fitted cables of 1.8 metres eliminate intermediate connections in most installations. Every additional junction in a high-current DC circuit is a potential source of resistance, heat, and failure — particularly in environments subject to vibration, moisture, and temperature cycling. Fewer junctions means better reliability, lower voltage drop, and less installation labour.
• Wide Input Voltage Range: 15–40V DC — Broader than the standard 18–35V range found on many 24V converters, the 15–40V window handles aggressive voltage sags during heavy engine starting or high load events, and accommodates higher absorption/equalisation voltages from some charger and alternator types without triggering an over-voltage shutdown.
• Stable Output Through Input Fluctuations — The wide input range ensures the 12V output remains stable and regulated when other high-draw equipment on the same 24V bus causes voltage sags or surges — important in shared electrical systems on trucks, vessels, and plant equipment.
• Overheating Protection — Built-in thermal protection allows the unit to operate safely in hot environments including machine rooms, enclosed engine bays, and confined equipment spaces. The converter manages its own thermal limits without requiring external thermal management or ventilation clearance.
• Compact 240W Output — At 20A / 240W, the ORI241220260 is the right-sized solution for dedicated 12V accessory circuits, auxiliary loads, communications equipment, lighting circuits, and small battery top-up applications running off a 24V primary source — without the overspecification and cost of a 70A or 100A unit.
• Non-Isolated Design — Input and output negatives are shared, which is the appropriate and efficient topology for the majority of automotive, marine, and off-grid 24V-to-12V conversion applications where galvanic isolation is not required.
