Energy control technology KUKJE ELECTRIC. MFG. CO., LTD. Digital UPS Energy-control Eco-system UPS Parallel Technology Hybrid ESS System Fire prevention ESS system Menu Digital UPS Energy-control Eco-system UPS Parallel Technology Hybrid ESS System Fire prevention ESS system Energy regeneration control technology Energy regeneration control technology with ‘energy saving load test’ function General load test method Install a resistive load, consume energy all as heat loss.It requires 110% electrical energy including losses from AC input power. 'Energy saving load test' technology (obtained patent and New Excellent Technology(NET), first commercialization in Korea) By controlling the AC circulation power, the AC output is circulated back to the input side and reused without using a resistive load.Only 10% electrical energy from AC input power is required, which is self-loss . Applicable fields UPS operation test under 100% load without additional equipment at the installed siteUPS 100% load operation test while it is in actual operation (e.g. for 100 kVA capacity under 50% load, operation test is on the remaining 50%)
