The Victron Orion-Tr 48/12-20A is a high-performance isolated DC-DC converter designed for demanding automotive, marine, and industrial applications. Delivering a stable 12 V output from a 48 V input, it ensures reliable power for sensitive electronics and auxiliary systems.
Features:
- Remote on/off terminal for low-power switching
- Short-circuit proof and parallelable
- High-temperature protection with automatic current reduction
- IP43 protection (screw terminals downwards)
- Easy-to-use screw terminals, no special tools required
- Input fuse on 12 V/24 V models (non-replaceable)
- Adjustable output voltage (not for battery charging; use Orion-Tr Smart for that)
