POWER SOURCE 3ZZI-5/x
Batteries 3ZZI-5/x are the power source for intrinsically safe devices in underground mining plants.
The 3ZZI-5/3 power source is used to power devices that draw a small current in the idle state, e.g. loudspeaker alarms, and is also used to power devices that draw a higher current, e.g. limit alarms.
The source elements are mounted in a plastic housing and hermeticized with a chemically hardened filler, creating a non-detachable functional block. The housing is equipped with two special connectors that prevent improper connections of the source with the powered system. The electronic system is assembled on a printed circuit.
