chargeable Battery station for I-TEL 2 +
When the mains voltage is present, the integrated mains transformer with appropriate rectifier and filter capacitor supplies the energy, at the same time the accumulator is charged via a current source. In the event of a power failure, the I-TEL is supplied by the built-in accumulator.
The battery station can bridge a mains voltage failure of 10 hours with a connected I-TEL, provided the battery is fully charged. For full charge the battery needs at least 12 hours.
It is recommended to leave the battery unit connected to the mains for a few hours before putting it into operation.
