TBS Omnicharge OCD 12/24-30 DC-DC Battery Charger

TBS Omnicharge OCD 12/24-30 DC-DC Battery Charger

The Omnicharge OCD is a programmable DC-DC battery charger built to charge an auxiliary or service battery from a vehicle's starter battery, even where the input voltage sits above, below, or equal to the output — a job a basic battery isolator or VSR can't do properly. The OCD 12/24-30 takes a 12V input and steps it up to a regulated 24V output at up to 30A continuous.

An intelligent IUoUo 3-stage, temperature-compensated charge profile suits flooded, GEL, AGM and LiFePO4 batteries, with programmable input voltage thresholds and an output status signal for automation or monitoring.
