Victron Skylla-TG 24/100 Battery Charger - 3-Phase
Pickup available at Mercury Yacht Harbour
Usually ready in 2-4 days
Description
The Skylla-TG 24/100 3-Phase is a 24 V, 100 A marine battery charger powered from a 3 x 400 V three-phase mains (320-450 VAC), making it well suited to larger vessels and commercial installations where three-phase shore or generator power is available. The three-phase supply is taken through an integral magnetic circuit breaker.
Charging follows the IUoUo three-step characteristic and is refined by the supplied battery temperature sensor and a voltage sense connection that compensates for cable losses. A separate 4 A second output keeps a starter battery topped up, while the unit can remain connected to the batteries throughout periods of storage.
The charger is housed in a sea-water-resistant aluminium enclosure, is force-cooled and rated IP21. Unlike the single-phase Skylla-TG models, the 3-phase version does not accept a DC supply.
