Description
The Victron Skylla-TG 48/50 is a high-performance charger designed for 48V battery systems, providing 50A charging current. Ideal for marine, off-grid, and industrial applications, it ensures safe and efficient battery charging with precise voltage control.
The charger features two outputs, one for the main battery bank and a second, lower-output (4A) for topping up a starter battery. This makes it perfect for systems with dual battery banks. In addition, the Skylla-TG charger allows the voltage to be precisely adjusted to suit the specific battery requirements, ensuring safe charging for both sealed and unsealed batteries.
The charger uses a microprocessor-controlled three-step charging process (IUoUo), ensuring rapid charging while safeguarding battery life. Additionally, temperature compensation helps extend battery life by automatically adjusting the charging voltage based on the battery temperature. This feature is particularly beneficial for sealed batteries, which can suffer from overcharging and damage if the temperature rises.
The charger is also capable of being used as a power supply in systems where batteries or large capacitors are not available, delivering stable and regulated output voltage.
Key Features
Features
Perfect chargers for any type of battery
Charge voltage can be precisely adjusted to suit any sealed or unsealed battery system. In particular, sealed maintenance free batteries must be charged correctly in order to ensure a long service life. Overvoltage will result in excessive gassing and venting of a sealed battery. The battery will dry out and fail.
Suitable for AC and DC supply (AC-DC and DC-DC operation)
Except for the 3-phase input models, the chargers also accept a DC supply.
Controlled charging
Every TG Charger has a microprocessor, which accurately controls the charging in three steps. The charging process takes place in accordance with the IUoUo characteristic and charges more rapidly than other processes.
Use of TG Chargers as a power supply
As a result of the perfectly stabilized output voltage, a TG Charger can be used as a power supply if batteries or large buffer capacitors are not available.
Two outputs to charge 2 battery banks (24V models only)
The TG Chargers feature 2 isolated outputs. The second output, limited to approximately 4A and with a slightly lower output voltage, is intended to top up a starter battery.
To increase battery life: temperature compensation
Every Skylla TG Charger comes with a battery temperature sensor. When connected, charge voltage will automatically decrease with increasing battery temperature. This feature is especially recommended for sealed batteries which otherwise might be overcharged and dry out due to venting.
Battery voltage sense
In order to compensate for voltage loss due to cable resistance, TG Chargers are provided with a voltage sense facility so that the battery always receives the correct charge voltage.
