D250TS
The D250TS has one 24 V input and two alternating outputs. One output charge a 24 V
battery and the other provides 50 % of the input voltage to the midpoint of a 24 V system. This
enables connection of 12 V consumers to the battery string and also equalizing this battery
string, for longer battery life.
D250TS
FEATURES:
• Multi-step10 A temperature compensated battery charging and battery maintenance.
• Battery separation of Starter and Service batteries.
• Equalization of Service batteries
• Makes connection of 12 V consumers directly to 24 V Service battery possible.
• When the charger is correctly connected the charger will output 24 V on the status signal wire.
