single-phasethree-phaselead-acid

SPH IND series represents the last transformer double conversion (VFI) power protection technology designed to protect a wide area of critical applications including server rooms, networks, telecommunication system, industrial processes and medical equipment. Unmatched reliability, excellent electrical performance, exceptionally compact size and outstanding cost-efficiency housed in an attractive enclosure are only some features of this new UPS solution. Monitoring and control data are shown on an easy to understand front panel display featuring pushbutton controls, LCD read out for event logs and diagnostics and a mimic diagram for system status. The power protection system can be remotely monitored via RS232, RS485, dry contact or SNMP interface. The SPH IND series is available from 10kVA to 100kVA models. PRINCIPLES OF WORKING The backup series is composed by: Rectifier, Inverter with transformer, Static Switch, manual by-pass and Battery. The Rectifier-Inverter line normally feeds the users, and the Battery is kept charged by the Rectifier. If a black out occurs, the Battery supplies power energy to users always through the Inverter. When the blackout is over, the Rectifier provides for Battery charge. If a short circuit or an overload occurs to the users, the Static By-pass switches the load over the emergency line. When the fault is over, the Inverter feeds users. FEATURES Backfeed protection to prevent voltage backfeed on the input line due to internal fault. Input power factor with full load 0.9. Output power factor 0.9. Zero transfer time. Parallelable features till 8 units as option. Filtered, stabilized and regulated sinewave supply.
