One full rated output and one 4 Amp output. Charge voltage can be precisely adjusted to suit any battery system. The input for the charger is 230V at 50/60HZ. Charge voltage can be measured directly on the battery terminals in order to compensate for voltage loss due to cable resistance. An external sensor allows measuring battery temperature and compensating charge voltage accordingly.

Delivery: 3-7 days

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.

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 sensefacility so that the battery always receives the correct charge voltage.
