An Uninterruptible Power Supply (UPS) has only one mission to protect the load when the power goes out. When a power disturbance occurs, mission critical power users, who cannot afford an interruption in power, need a method to bridge the gap between the loss of utility and Emergency Generators
“Blue Whale BWUL series is a double conversion system with sinewave output. It supplies
continuous, stable, clean power for commercial and industrial environments. When the
utility power is lost accidentally, the UPS system will use the power from battery to output
without interruption.”

“BWUL UPS is applied an advanced digital controller to control the double conversion
system, and with an isolated transformer at the output to protect the load and the UPS
itself. The UPS is also built-in user-friendly LCD interface and multiple communications
including Modbus, RS-232 and intelligent slot. With free download software, this UPS
provides complete power solution of monitoring and controlling remotely.”
