Advance Galatrek's latest three-phase uninterruptible power system (UPS) is designed to deliver sinewave power protection up to 30kVA, and offers a wide variety of customisation and communication options.

The MasterElite MultiTec MRT UPS offers highly flexible power protection, and is ideal for use in LANs, servers, data and comms centres, Internet applications, point of sale (PoS) systems and medical environments.

The MasterElite MultiTec MRT is available in capacities up to 30kVA, and is available as a three-phase-in/three-phase-out unit, making the UPS perfect for demanding loads in mission critical environments everywhere.

MasterElite uses dynamic input and output filters to protect the load from upstream electrical pollution, and continues to provide spike and electrical noise protection even when the unit is in static bypass mode.

Innovative MultiTec technology enables MasterElite users to alter the UPS operation mode to match the sensitivity of the connected load and the characteristics of the mains power supply.

The user can instruct the UPS to operate either on-line or in economy mode, either remotely or from the main control panel on the unit.

MasterElite's online mode adopts the traditional double-conversion principle, where the inverter continuously powers the load, for a stable, break-free supply.

In economy mode, the advanced MultiTec circuitry mimics the characteristics of a digital line interactive UPS, with the load being powered through dynamic filters.

This enables the inverter to remain active but not powering the load, until the mains fluctuates or fails suddenly.

Overall efficiencies exceeding 98% are achievable, resulting in a reduction in overall wear and tear on the UPS assemblies.

This makes economy mode ideal for locations where the mains is relatively stable, or the load less critical.

MasterElite's robust circuitry offers powerful protection against surges, sags and brownouts in the mains power supply, generating a stable sinewave output over a very wide input voltage range, without the need to resort to battery power.

This allows MasterElite to deliver high quality mains power even down to 140V AC, while providing an exceptional ride through capability that allows it to handle mains power failures of up to 40ms, without switching to battery power.

In addition to being virtually silent, MasterElite MultiTec MRT makes full use of microprocessor control to provide the ultimate stability and reliability.

Front-end power factor correction (PFC) circuits achieve a true sinewave output, and give superior flexibility and economy.

An easy to use front panel keypad and LCD display give full access to unit status, while an RS232 port allows integration with existing communications networks, using the PowerShield2 management software supplied with the UPS.

The MasterElite MultiTec MRT features built-in automatic static and manual maintenance bypasses, with automatic or manual battery testing facilities.

External maintenance bypasses and dual-redundant switches can also be specified.

The unit is also compatible with extended battery packs, AC diesel and LPG generators.
