Master HE UPS with Online topology, high efficiency and reliability, provides maximum protection for sensitive consumers. Design in accordance with IEC 62040-3 and VFI SS 111 and inverter based on isolated transformer, has resulted in high quality voltage and output frequency of this UPS. The output power factor of this UPS is one; This feature makes it possible to power a variety of consumers (ohmic, inductive and capacitive loads) to a certain extent. Despite having an isolated transformer, thanks to the use of a microprocessor processor and a high-frequency three-level inverter in this UPS, the efficiency of the device is about 95.5% in Online mode, which this amount considering the losses caused by adding Isolated transformers are created in the circuit, comparable to the best Transformer-less UPS on the market.

This UPS is compatible with all types of diesel generators and synchronizes well; In addition, it protects the consumer from any kind of noise that may be caused by the use of diesel generators. The effectiveness of input power (whether mains electricity or diesel generators) in terms of power supply to consumers by UPS is zero. The fans installed in the upper part of the device practically eliminate the need for lateral or back access to the UPS and allow the UPS to be placed near the wall. Master HE takes up as little space as possible; 200kVA requires a little over half a square meter of space for installation. The feature of power expansion or increase of system reliability (Redundancy) is available by parallelizing up to 8 UPS devices (n + 1) even non-power. In Smart Active UPS mode, by monitoring the quality of voltage and input frequency, it automatically decides on the power supply of connected consumers through the inverter or bypass path, and this, the overall efficiency of the system up to 98.5% in this The working situation increases. 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 UP S is well predicted.
The high capacity of the MTBF index (average time between failures) in this UPS is about 250,000 hours, which shows the high reliability of Master HE and the long useful life of the device. 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. The LCD display with a resolution of 240 x 128 pixels and a user-friendly appearance displays the input, output, load percentage and battery charge well. The working status of the UPS and the internal elements of the device are displayed graphically.
(1) To perform the parallel operation, the Parallel kit must be provided with the relevant connections for each UPS.
(2) UPS monitoring under TCP/IP protocol requires NetMan 204 module and under Modbus/Jbus protocol requires MultiCOM 302 module.
