GK75A Power Supply is a high voltage generating source for active ionization devices. Its set-up and operation is simple and doesn't need any extra care. Operation of more than one static bars is possible. There is a protection card for the system security in case of a short-circuit. This protection card cut down current and disables circuit in case of a short-circuit in the connected the high voltage cable of ionization devices or ionizer. In this case, the transformator included in power supply operates longer and more secure.
