Description
The Skylla-TG 24/50 is a robust, microprocessor-controlled 24 V marine battery charger that delivers up to 50 A from a 230 VAC supply. It can also be used as a stabilised DC power supply where a regulated 24 V output is required.
Charging follows the IUoUo three-step characteristic, with a supplied battery temperature sensor and battery voltage sense ensuring an accurate charge in all conditions. A second 4 A output is provided to keep a starter battery topped up alongside the main house bank.
Built into a sea-water-resistant aluminium enclosure with forced-air cooling and an IP21 rating, the charger is designed for the marine environment and can stay connected to the batteries during storage.

How many batteries can the Skylla-TG 24/50 charge at once?
The Skylla-TG 24/50 has two isolated outputs, so it can charge two battery banks at the same time. The main output delivers the full charge current to the house bank, while a separate output provides up to 4 A to top up a starter battery.
What charge profile does the Skylla-TG 24/50 use?
It uses the IUoUo three-step charge characteristic, charging in bulk, absorption and float stages with an absorption voltage of 28.5 V and a float voltage of 26.5 V. The absorption time can be set to 4, 8 or 12 hours to suit your batteries.
Can the charger stay connected to the batteries permanently?
Yes. The charger can remain connected to the batteries at all times, making it well suited to keeping a vessel topped up during storage. The float stage maintains the batteries without overcharging them.
How does the charger compensate for temperature and cable losses?
A battery temperature sensor is supplied as standard, allowing the charge voltage to be adjusted for battery temperature. Battery voltage sense further compensates for voltage loss in the cabling of up to 2 V, so the batteries receive the correct charge voltage.
Can the Skylla-TG 24/50 be used as a DC power supply?
Yes. As well as charging batteries, the Skylla-TG 24/50 can be used as a stabilised DC power supply, providing a regulated 24 V output for connected equipment.
