Victron Energy ORI241221226 Orion IP67 24/12-100A (1200W)

Victron Energy Orion IP67 24/12-100A 1200 Watts. Weatherproof. Ready for the Real World.

Product Overview

The Victron Energy Orion IP67 24/12-100A (ORI241221226) is a high-power, non-isolated DC-DC step-down converter rated at 100 amps and 1200 watts continuous output, converting a 24V DC source to a regulated 12V DC output. Where it separates itself from the standard Orion range is its IP67 rating fully dustproof and protected against water immersion to one metre depth making it one of the few 1200-watt DC-DC converters genuinely suited to harsh outdoor, marine, and off-road environments without requiring an additional protective enclosure.

With an input voltage range of 18–35V DC, the ORI241221226 handles real-world 24V system fluctuations comfortably from partially discharged battery banks through to absorption charging voltages. Its 97% efficiency at half load and 96% at full load means less than 4% of your input power is lost as heat even at maximum output exceptional for a converter of this current rating, and critically important in Australian conditions where operating temperatures already challenge thermal margins. Non-isolated by design, input and output negatives are shared appropriate for the vast majority of automotive, marine, and off-grid applications where galvanic isolation is not a requirement.

Features & Benefits

• IP67 Weatherproof Rating — Fully dustproof (IP6x) and protected against water immersion between 15cm and 1 metre depth (IPx7). No external enclosure required for exposed outdoor, underfloor, underbonnet, or marine bulkhead installations. A significant practical advantage over IP20-rated converters that demand a protected panel install.
• 1200W Continuous Output at 100A — Serious, sustained 12V power from a 24V source. Suitable for powering entire 12V accessory circuits, auxiliary battery charging, refrigeration systems, lighting banks, communications equipment, and high-draw 12V loads on commercial vehicles, heavy trucks, marine vessels, and large off-grid systems.
• 97% Efficiency at Half Load / 96% at Full Load — At these efficiency levels, the converter generates minimal heat even under full 100A continuous load. Less heat means longer component life, lower thermal stress on adjacent wiring and equipment, and reduced need for active cooling or heat management in the installation space.
• Input Voltage Range: 18–35V DC — Accommodates the full realistic operating range of a 24V battery system — from a partially discharged 24V bank (18V minimum) through resting voltage, bulk charge, and into absorption at the top of the range (35V maximum). The converter remains stable and in regulation throughout, without nuisance drop-outs or shutdowns during charging cycles.
• Regulated 12V Output (±3% Tolerance) — Output voltage is held within ±3% of 12V across the operating range, ensuring connected loads and charging circuits receive a consistent, stable supply regardless of input voltage variations.
• Non-Isolated Design — Input and output negatives are shared (common ground). This is the correct and appropriate topology for the large majority of automotive, marine, and renewable energy DC systems where galvanic isolation between the 24V and 12V circuits is not required. Delivers higher efficiency and lower cost than an isolated equivalent at this power level.
• Compact Form Factor for 1200W Output — At 265 x 127 x 63 mm, the ORI241221226 is compact relative to its output rating. Its physical size and IP67 housing open up mounting locations — underbonnet, underfloor, bulkhead, or chassis rail — that a rack-mount or panel-only unit cannot access.
