ON-LINE DIGITAL UPS SYSTEMS

Tetra Controls offers On-Line Digital UPS Systems. It is digitally controlled. Features: Digital sine wave generation, on-line diagnostics, synchronised static by-pass switch, digitally controlled business logic, active EMI cancellation technique, alpha numeric back light LCD, RS 232 to connect with host computer, IGBT short circuit protection by software and over temperature shut down. It operates reliably and in normal mode in a wide input voltage range of 165 V to 260 V supplying a steady output voltage. The overall efficiency of the UPS system is more than 87% thereby saving a lot on the running cost of the UPS system. The output voltage is a steady (230V ± 1%), high quality sinusoidal voltage with very low harmonic distortion 230 V AC single phase, modular design; IGBT based double conversion; and EMI line filters.
