UPS Master Industrial provides maximum protection for systems and equipment in industrial plants, manufacturing, petrochemical industries, power distribution and power plants. Master Industrial is an online topology UPS compliant with IEC EN 62040-3 and VFI-SS-111 and equipped with isolated transformers at the input and output. This UPS is an ideal option for working in harsh and unfavorable environmental conditions; The normal operation of the UPS under conditions of vibration, mechanical stress, dust and harsh environmental conditions is largely guaranteed. Thanks to the high capacity of short circuit current, loads with high instantaneous currents such as motors, compressors, etc. are fed without damaging the output voltage of the UPS.

The feature of power expansion or increase of system reliability (Redundancy) is available by parallelizing up to 8 UPS devices. (3) User-friendly LCD display displays the values of different device parameters well. With RS-232 serial port, remote emergency terminal (EPO) and two slots for communication equipment such as NetMan 204 module, parallel card slot, Multi I/O card slot and relay contacts, any possible connection to this UPS is well predicted. The Maintenance Bypass switch is located in this UPS to transfer the power supply of consumers from the inverter to the main input power without any interruption. This UPS comes with IP20 protection by default; It is possible to increase the permeability coefficient to IP31 and IP42 if ordered.
(1) It is possible to order a battery box compatible with the body of the device.
(2) UPS monitoring under TCP/IP protocol requires NetMan 204 module and under Modbus/Jbus protocol requires MultiCOM 302 module.
(3) In order to perform the Parallel operation, a parallel card with the corresponding connections must be provided for each UPS.
Master Industrial UPS is suitable for use in data centers, computer networks, laboratory medical equipment, transportation and navigation equipment, industrial plants and safety and security systems. The selling price of this UPS varies depending on the model and power requested. Please contact the sales department of Zener Engineering Company to find out the inventory, receive the price list and purchase the various capabilities of this UPS.
