Battery Charger


GCBF-04 is a unit supplying continuous voltage of which the main application is as battery charger, being able to be used in other applications as continuous voltage source.
As a charging unit, it is used to charge batteries, as well as to maintain their voltage.
It is possible to supply several consumers simultaneously (parallel load operation).
GCBF is short circuit proof, and so it is not necessary to disconnect the charging unit during an operation which could cause a small short circuit (for example the start of a diesel engine). Single-phase input 110/220Vac and voltage output 12V or 24Vdc.
Output current 6A when the voltage is 12Vdc or 3A when the voltage is 24Vdc.
