Features:

      HIGHLIGHTS

• 3-Level Rectifier and Inverter adopts IGBT Topology
• Ultra High Energy Efficiency >96.6%
• Full Rated Power Factor kVA=kW
• Parallel expansion to reach upto 8 MW
• N+N, N+1 redundancy mode configurable
• Automatic input phase reversal protection
• High input voltage range saves battery power
• Compatible for 100% regenerative loads with bidirectional power converters

   Innovative 3-Level Topology

• GTC-MW Series with Innovative 3-Level Topology is a true on-line double conversion, three-phase UPS system that provides one of the highest level energy efficiencies in the industry.
• 3-level inverter & rectifier design GTC-MW Series brings the newest power conversion technology and delivers efficiency up to 96.6% at 40-70% load operation which is the most common operating range.

  High Efficiency & Low Total Cost of Ownership

• Less energy consumption to supply the loads, thanks to high efficiency up to 96.6%.
• Reduced energy losses.
• Reduced electricity usage and air conditioning requirements.
• Reduction in operating cost of UPS.
• IGBT based power factor correction technology provides input power factor close to 1 (≥ 0.99). The high input power leads to reduced electricity pay-out, minimizes cable, switchboard, fuse and generator requirements, thus reducing investment cost.
• Low input current total harmonic distortion (THDi) less than 3% helps to avoid the disturbance and expensive harmonic filters.
• Small footprint and easy maintenance.

   High Output Power Factor 1

• Output power factor of 1 (kVA=kW) rate provides up to 25% more active power than a traditional UPS.
• Suitable for modern power supply application with unit or capacitive power factor (e.g. new servers generation).

   Reverse Energy Tolerance for Regenerative Load

• GTC - MW can be used with regenerative loads such as synchronous motors. The regenerative loads pump the energy back to mains, traditional UPS system burn this feedback energy and this causes lower efficiency. GTC - MW UPS with IGBT rectifier are able to absorb intermittent load generated power. Additionally, this reverse power tolerance permits execution of important system operations like closed transfers of the UPS load directly to an engine generator source.

Overview:

Flexibility

• Temperature sensor for external battery cabinets for extended runtimes.
• External battery cabinets for different sizes of batteries to provide extended runtimes.
• Frequency converter mode.
• Compatible version with EN 50171 for supplying power to emergency lighting systems

   Perfect Generator Compatibility

• GTC - MW is Perfectly compatible with diverse sources, especially with generators. When generator power is used, thanks to its robust IGBT rectifier, it ensures clean, uninterrupted power to protected equipment. With high input power factor performance of GTC - MW it is enough to chose generator with power only 20% higher rated then the UPS. GTC - MW has the ability to adjust power walk in from 5 to 60 seconds, along with reduced input current distortion.

   Maximum Availability

• Parallel configuration up to 8 units per redundancy (N+1) and power increase, upto 8MW
• Loop connection helps the UPS system to continue the operation when the connection cable is inturrupted.
