Prolink Master II Series (1P/1P) Tower Type is a single-phase UPS system that employs a true online double-conversion technology. UPS system is designed to deliver clean and high quality electrical power to fully protect critical devices such as sensitive networks, small computer centres, servers, medical equipment, telecom applications as well as industrial applications. High input power factor correction in the system improves the eciency and reduces overall losses. UPS is equipped with 3-stage smart charging design to optimize battery performance. This feature extends the useful service life of battery and optimizes battery recharge time. Users can easily monitor and access to their UPS status from a comprehensive LCD display. The UPS systems have USB and RS-232 communication ports as standard, with a built-in intelligent slot for additional adapters, protocol converters and relay contact cards. SNMP option is also available for power management via SNMP manager and web browser. The Master II series (1P/1P) Tower p.f 0.9 Type is available in capacities ranging from 1KVA to 3KVA. Programmable power outlet feature is implemented in the system so that during power failure, this enables users to extend battery time to critical devices by shutting down the non-critical devices. In addition, Emergency Power O (EPO) function is also available for UPS models and which is used to protect the personnel and the equipment in case of fire outbreak or other types of emergency.
