BT – INDUSTRIAL UNINTERRUPTIBLE POWER SUPPLY (UPS) UNITS ON-LINE DOUBLE CONVERSION

The new BT three-phase range joins the current lineups with specific INDUSTRIAL characteristics. Power range in stand-alone systems from 200kVA to 1000kVA. Parallel capability up to 8 units. The main features that distinguish it are technical and structural robustness and latest-generation 3-level technology. This range is recommended for those who have power supply problems with micro-interruptions, mains failures, and grid instability, with a correction of ±20%. In high-power installations, where the main production grid or high-power electrical lines are supplied, from 200kVA to 1MW, equipment failures and production downtime can be avoided, resulting in significant savings that can be classified as Industry 4.0.

Main features:

• Cos-phi 1.0
• Input harmonic distortion ≤ 3%
• System efficiency up to 96%
• Dual power input
• Parallel up to 8 units
• Charging capacity from 80 A to 340 A
• Ability to power inductive and capacitive loads with 100% imbalance
• Standard interfaces: RS232 and 485 Modbus
• Backfeed present
