Specifications
Product Description
The Victron Skylla-TG 48V 25A (1+1) Charger is a professional high-frequency charger designed for 48 V systems that require precision, reliability, and continuous availability. Its microprocessor control applies a 3-stage IUoUo curve that adapts the absorption time to the actual condition of the battery, preventing overcharging and shortening recharge times. It features a main 25 A output for the service bank and an isolated auxiliary output (~4 A) with slightly lower voltage to maintain the starter battery. With a universal input of 185–264 VAC (45–65 Hz) and also 180–400 VDC, the Skylla-TG offers great flexibility both on-grid and with generators or DC bus. It includes a temperature sensor and voltage probe to compensate for cable losses, achieving precise charging voltages and extending battery life.
Main Features
- Main output 25 A and auxiliary ~4 A (1+1) at 48 V; the auxiliary maintains the starter battery.
- 3-stage IUoUo curve (bulk, absorption, and float) with adjustable absorption and “Intelligent Startup”.
- Input 185–264 VAC PF=1 or 180–400 VDC; stable with grid, generators, or DC bus.
- Automatic thermal compensation and voltage probe for precise terminal charging.
- Stabilized power supply function: can operate without a battery connected.
- Forced ventilation and comprehensive protections: overtemperature, short circuit, reverse polarity, and overvoltage.
Advantages or Benefits
- Longer battery life (AGM, GEL, open lead-acid, and LiFePO₄ with BMS) thanks to precise voltages and temperature compensation.
- The auxiliary output avoids installing splitters or relays to maintain the starter accumulator.
- Power supply versatility (AC/DC) for professional environments and vessels with generators.
- 24/7 operation with minimal maintenance and proven reliability in marine and industrial applications.
Purpose or Applications
Ideal for yachts and sailboats with a 48 V bank, intervention vehicles, mobile platforms, and stationary panels (telecom, security, backup) that require precise, fast, and safe charging with starter battery maintenance.
