FUNCTIONALITY
The D250TS has three operating modes:
1. 4-step charging of a Starter battery.
2. When Starter battery is fully charged: Equalization of a Service battery on the Input side. This
function provides the possibility to connect 12 V consumers to the 1st battery in the Service
battery string.
3. Monitoring. The D250TS now monitors if the Starter battery needs charging (priority) or the
Service battery needs equalization.
