Foshan Baykee New Energy Technology Incorporated Company

This UPS from the CHP3000 series adopts the world's most advanced DSP digital control technology. The capacity, the reliability and the performance are all of the fist-class level among the world. The single-machine capacity is ranging from 10KVA and 800KVA, widely used in the telecom, bank, bond, traffic, utility, manufacture, etc.   Pure sine wave output, true on-line dual conversion design.   Adopt 4 layer PCB, and SMD technology.   High efficiency IGBT (Insulated Gate Bipolar Transistor) inverter technology.   Touch screen display, with the simple operation and Intuitive data, optional display language and logo.   Super-speed microprocessor, CPLD, the 6th generation low loss superpower IGPT and static switch together deduced a legend of digital times.   Set the work mode on the display directly, UPS mode, ECO mode, EPS mode.   Intelligent detecting function.   Excellent load feature: it is completely capable to load from 0-100% while no need to change to bypass, which make sure the output reliable.   Three phase separately control, realizes the control of instantaneous over~loading balance, so as to reach 100% unbalanced load.   Cold start: when mains failure, can directly use the battery to start the ups until the battery discharge to low voltage, when mains recover, can self start UPS.   Generator compatible: according to the real electric circumstances, UPS can be compatible to the generator, highly improve the generator input efficiency, save the energy.   Intelligent communication: with RS232 and RS485 standard collocation, optional SNMP and dry contact   Perfect protection: input/output over/low voltage protection, input surge protection, phase sequence protection, battery over charge/discharge protection, short circuit protection, over-temperature protection and so on, as well as alarm function.   Selectable battery inspection module: can test the single parameter and display on the LCD, battery failure will immediately alarm and inform the administrator.   High-powered dynamic feature: adopt kinds of feedback control such as instantaneous control mode and virtual value, not only reach the high dynamic adjustment, but also reduce the output voltage distortion.   Optional input harmonic filter or 12 pulse rectifier: effectively restrain the input THD, raise UPS input power factor, reduce the input THD current.   The CHP3000 series UPS has entirely surmounted the technical bottleneck in analog circuitry age, ingeniously applied the digital control technology and high-accuracy SMD technology which assured ultra-high system stability and is able to fully acclimate various grid environment.
