ZIM-BX - Intrinsically Safe Power Supply

Intrinsically safe power supply type ZIM-BX is designed to supply electrical and electronic installations, especially the intrinsically safe control and signaling systems. Stabilized output voltage allows the use of power supply to power the microprocessor controllers. It is characterized by high stability of the output voltages at the volatile input voltage, which changes may take place in the range from 36V to 75V (for power supply in "L") with DC current or from 35V to 54V with AC current and from 80V to 250V (for power supplies as "H") when powered by AC voltage. Connecting the power supply is done by output junction chamber equipped with two conduits. Power supply type ZIM-BX can be supported by two independent outputs with different values o f current and voltage according to the customer needs. It is equipped both with an LCD display, giving the ability to monitor voltage and current values o f output and with RS-485 port for remote reading made for monitoring purposes on the surface of t he mine. Power supply type ZIMBX/ A is equipped with two signal LEDs, but does not have LCD display and RS-485 communication protocol.
