New UPS for medium-sized data and voice
networks
Advance-Galatrek has developed a brand new range of single phase and three phase Uninterruptible Power Systems designed to deliver sinewave power protection up to 20kVA
Advance-Galatrek has developed a brand new range of single phase and three phase Uninterruptible Power Systems (UPS), ideal for use in medium-sized professional data and voice processing environments The units are designed to deliver sinewave power protection up to 20kVA, and offer a wide variety of customisation and communication options, to provide a highly flexible power protection installation
MasterElite MultiTec offers users the option of specifying either single phase in - single phase out; three phase in - single phase out or three phase in and out models, each with capacities ranging between 10kVA and 20kVA.
Every MasterElite MultiTec version uses dynamic input and output filters to protect the load from upstream electrical pollution.
These state of the art filters even continue to provide spike and electrical noise protection when the unit is in static bypass mode.
The robust circuitry built into MasterElite provides powerful protection against surges, sags and brownouts in the mains power supply.
Every model can generate 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 140 volts AC.
Every model boosts an exceptional ride through capability that allows MasterElite units to handle mains power failures of up to 40ms, without switching to battery power.
The brand new MultiTec technology enables every MasterElite UPS to alter its operation mode to match the sensitivity of the connected load, and to adjust to the characteristics of the mains power supply.
Either from the main control panel situated on the front of the unit, or even remotely, the user can instruct the UPS to operate either on-line or economy modes.
MasterElite's on-line 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 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.
In addition to being virtually silent, MasterElite models make use of full microprocessor control to provide each unit with 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 PowerShield management software supplied with the UPS.
All MasterElite models have been designed with safety, ease of access and maintenance in mind.
Each model features built-in automatic static and manual maintenance bypasses, with automatic or manual battery testing facilities.
External maintenance bypasses and dual-redundant switches can be specified for each model.
All versions allow the addition of extended battery packs and AC diesel and LPG generators, to supplement existing batteries.
