Hm Series 10-210kVA Modular UPS

HM series modular 3-phase digital information, networking online intelligent pure sine wave uninterruptible power supply is based on reliable, advanced, high efficiency digital analogy hybrid technology UPS system that provides the user with clean computer grade power for continuous operation of his critical load, regardless of any disturbance on the upstream AC power. The system offers many innovative features to give the user maximum reliability and flexibility at the lowest operating cost.IGBT RectifierEmploying the latest rectifier technology, modular IGBT rectifier offers an input power factor of greater than 0.99, and input current distortion of less than 3%. Therefore it does not pollute the input utility supply or other devices sharing the same utility source.IGBT InverterHigh speed IGBT inverter gives low output distortion and clean sinusoidal waveform for excellent performance and high reliability. Both IGBT rectifier and inverter share common parts which mean the UPS is easier to maintain.Digital Signal ProcessingThe modular uses the most advanced DSP technology. Using high sampling rate possible only with DSP, output and system parameters are tightly controlled and maintained throughout the various modes of operation.100% Unbalance load capability3-phase independent modulation, full bridge inverter designed, it can be 100% unbalance load in 3-phaseParalleling CapabilityThe modular can be paralleled up to a maximum of four single modules for added capacity or redundancy. The units can also be installed in a Hot-Standby configuration for added reliability and flexibility.Wide Input Voltage RangeThe modular features a wide input voltage range of +15%, -20% at full load under normal conditions. This is extremely useful in very poor input power supply situations as the battery energy is not utilized and can be preserved for more prolonged outages.Complete protectionsWith various system protections, as over voltage, low voltage over current, over load, short circuit, etc can be detected and supply reliable protections.High Efficiency ECO ModeIn situation where the utility supply is relatively stable the modular can be set to energy saving ECO mode. An efficiency of greater than 97% can be achieved. The load is never in danger as the switching is done by high speed solid state devices.Intelligent Battery ManagementProper testing, charging, discharging and management of the battery system is a very important aspect of the UPS control system. In the modular UPS, the batteries are constantly monitored by an intelligent battery management algorithm. Any fault detected in the batteries is immediately reported to the user.User Friendly Display and CommunicationDual-color LED indicates the status of major modules. The neatly displayed push-buttons give functions such as menu selection, inverter startup and shutdown, emergency shutdown and alarm. The large LCD graphical display provides an array of performance parameters, fault information and historical event log that are useful for troubleshooting.The system provides voltage-free relay contact of common alarms, RS232 & RS485 signals for remote monitoring, and SNMP (optional) for web-based monitoring. With self-diagnosis and self-protection, audio and visual alarm indications are available and these alarm notifications can be sent by e-mail or paging to the service personnel.ApplicationFinance,Insurance,Taxation,Telecom,Traffic,Military,Security,Energy,Education,Government,Industry
