Industrial online UPS 20kva power supply
Power supply brief introductions:
L series 3/3 low frequency on-line intelligent digital UPS congregates the essence of POCASA technology and entirely breaks the bottleneck technology in traditional simulation circuit era. It adopts the digital control technology, of which the core is high-speed MCU and CPLD. It takes the 6th generation low-exhaust and big-power IGBT and static switch as power devices. Guided by these most advanced technologies in the world, it is really the first-class product.
L series 3/3 low frequency online UPS also adopts 4 layer PCB. The capacity can be from 10KVA~400KVA, be widely applied to the telecommunication, bank, stock exchange centre, transportation, electricity, industry etc.
Power supply key features:
a).Pure sine wave output, true on-line dual conversion design
b).Adopt 4 layers PCB, and SMD technology
c).High efficiency IGBT (insulated gate bipolar transistor) inverter technology
d).Touch screen display, with the simple operation and Intuitive data, optional display language and logo
e).Set the work mode on the display directly, UPS mode, ECO mode, EPS mode
f).Intelligent detecting function
g).Excellent load feature
h).Three phase separately control, realizes the control of instantaneous over-loading balance, so as to reach 100% unbalanced load
i).Cold start
j).Generator compatible
k).Intelligent communication
l).Perfect protection
m).Selectable battery inspection module
n).High-powered dynamic feature
