Intrinsically safe power unit ZIM
Intrinsically safe power unit ZIM is designed for operation in sub-surface mine workings in rooms classified a, b and c category of methane explosion hazard. It supplies power to intrinsically safe electrical circuits.
Power unit ZIM is an impulse power unit. It is defined by high output voltage stability with unstable input voltage, which allows variations within the range from 20 to 100 V (for power units of version “L”) or from 100 V to 300 V (for power units of version “H”) if supplied by direct or alternate current.
Depending on customer’s needs power units ZIM can be provided with four individual outlets with various current and voltage values.
Power units are equipped with the system visualizing capacity by means of light-emitting diode.
