Description


Dual input 20A charger with selectable charge voltages


The D250SA is a fully automatic, 5 step charger that supplies up to 20A of power to any 12V lead acid service battery from 40-300Ah, including Wet, EFB, MF, Ca/Ca, AGM and Gel. It has selectable charge voltages for AGM batteries and can use power through its dual input from alternator, solar panel and wind power. When the service battery is fully charged, the D250SA will automatically redirect maintenance charge power to the starter battery. The D250SA can maintain a stable output up to 20A to vehicles fitted with smart ECU controlled alternators and also has a temperature sensor for optimised charging, regardless of weather conditions.

Features

Charging category
DC charging
Back current drain*
Corresponding to less than 1 Ah/month
Back Current Drain TEXT
*) Back current drain is the current that drains the battery if the charger is not connected to the mains. CTEK chargers have a very low back current.
Battery voltage
12 V
Battery chemistry
Lead acid (AGM, GEL, EFB, MF, CaCa)
Ambient operating temperature
-20 ˚C to +50 ˚C (- 4 °F to +122 °F)
Input
11.5–23 V, 25 A
Output
14.4/14.7 V, 20 A
Ripple**
Less than 4 %
Ripple TEXT
**) The quality of the charging voltage and charging current is very important. A high current ripple heats up the battery which has an aging effect on the positive electrode. High voltage ripple could harm other equipment that is connected to the battery. CTEK battery chargers produce very clean voltage and current with low ripple.
