POWER SUPPLY ZIS-x/10/y, ZIS-x/10/y/T, ZIS-x/10/y/L, ZIS-x/10/y/TL
The intrinsically safe mains power supply is designed to power intrinsically safe devices in underground mining facilities.
The ZIS-x/10/y type power supply is designed to power intrinsically safe devices in underground mining plants, with the "ib" output protection degree, M2.
The power supply is housed in a durable metal housing covered with an anti-corrosion galvanic coating and powder coating, which has three chambers: the upper one – for connecting the mains power supply (pass-through), the middle one – for housing the power supply electronics assembly, and the lower one – for connecting the output circuits.
The power supply is available in 4 main versions:
ZIS-x/10/y – basic version with relay contact to confirm output voltage. Supply voltage range 42-230Vac.
ZIS-x/10/y/ T – version with added RS485/Modbus communication module. Communication allows remote reading of power supply parameters and the ability to remotely turn off the output voltage.
ZIS-x/10/y/L and ZIS-x/10/y/TL – versions with similar functionality adapted to low-voltage power supply in the range of 24-42Vac, 24-60Vdc.
Each power supply has an LED to indicate the operating status of the power supply.
Each power supply comes in any combination of output current and voltage, as shown in the table below.
