Orion 24/12-70A DC-DC Converter IP20
Professional DC-DC converter. 24V to 12V step-down. 70A continuous output. 92% efficiency. Adjustable output voltage. Non-isolated.
Step Down High Power
Converts 24V DC to a stable 12V DC output, allowing you to power 12V appliances, lights, and accessories from a 24V battery bank. Perfect for trucks, commercial vehicles, marine systems, and off-grid setups where a 24V system is used but 12V equipment needs to be powered.
Adjustable Output Voltage
The output voltage can be adjusted between 10V and 15V via an internal potentiometer, with a default setting of 13.2V. This flexibility allows the unit to also function as a battery charger — for example, to charge a 12V starter or accessory battery in an otherwise 24V system.
Remote On-Off
The remote on-off connector eliminates the need for a high-current switch in the input wiring. Operate the converter with a low-power switch or connect directly to the engine run/stop switch for automatic control.
Parallel Operation
All models with adjustable output can be paralleled to increase output current. Up to five units can be connected in parallel, allowing you to scale your power conversion capacity as your system grows.
Temperature-Controlled Fan
Features a temperature-controlled fan for quiet, efficient cooling. The fan only activates when needed, keeping noise to a minimum during normal operation.
