CTEK D250SA DC-DC battery charger



Enertec Batteries has introduced the uprated CTEK D250SA 20A DC-DC battery charger.


This unit is ideal for charging a dual-battery set-up when no AC power is available.

Whether it’s from a smart alternator or a solar panel, or (as of now) both at the same time, the D250SA’s five-step process will restore your charge on the go without compromising your vehicle’s electrical systems.

It’s even splash- and dust-proof!

The new upgraded D250SA has finally arrived and offers unique features such as smart alternator compatibility while the advanced MPPT solar regulator will even charge the vehicle starter battery when connected to a solar panel.

The unit retails for around R5600.00 vat inclusive.

With award winning Swedish technology, the dual input D250SA can draw its power from smart alternators and other DC sources, making it the ideal charger for vehicles that don’t have access to a mains power supply. Its dual input capability means it can draw power from solar and wind sources, in parallel to the alternator.

The D250SA is a fully automatic, 5 step charger that supplies up to 20A of power to charge, condition and maintain any 12V lead acid service battery from 40-300Ah, including Wet, MF, Gel, AGM. EFB and Ca/Ca.

The D250SA uses patented technology so it’s safe for you and your vehicle’s electronics. It’s also IP65 classified (splash and dust proof, and suitable for outdoor use) and comes with a 2-year warranty.
