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 12V 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.
