Victron Skylla-TG 48/25 (1) 230V Battery Charger 25A 48V

Victron Skylla-TG Battery Charger for 48V Batteries

One output with full rated power and a secondary charging output with 4 A are available. The charging voltage can be precisely adjusted to any battery system.
The input for the charger is 230 V at 50/60 HZ. The charging voltage can be measured directly at the battery terminals to compensate for voltage loss due to cable resistance. An external sensor allows measuring the battery temperature and compensating the charging voltage accordingly.

Pure Power, Compact Format

TG generation battery chargers are light and compact due to the use of high-frequency technology. The charging voltage can be adjusted to any open and sealed battery type. A stable charging voltage is particularly important for sealed, maintenance-free batteries. Overvoltage leads to excessive gas evolution and drying out

Controlled Charging

Each TG charger has a microprocessor that precisely controls the charging process in three stages. The charging process follows the IUoUo characteristic and is faster than other charging processes.

Usable as Power Supply

Thanks to its perfectly stabilized output voltage, a TG charger can be used as a power supply in the absence of batteries or large buffer capacitors.

Two Outputs for Charging Two Batteries

TG chargers have two isolated outputs. The second output is intended for charging a starter battery. It has a slightly lower output voltage and is limited to 4 A.

Higher Battery Life through Temperature Compensation

A temperature sensor is included with every TG charger. The temperature sensor ensures a decreasing charging voltage as battery temperature increases. This is particularly important for maintenance-free batteries, which could otherwise dry out due to overcharging.

Voltage Sense: Measuring the Charging Voltage at the Battery or DC Distributor

To compensate for voltage losses due to cable resistance, TG chargers have a "Voltage Sense" function. It ensures that the battery always receives the correct charging voltage.
