UPS Power Supply
Product Overview:
LCX Power-HUPSG industrial frequency impact-resistant uninterruptible power supply adopts true online double-conversion topology with built-in power frequency isolation transformer and full digital DSP control.
Benefiting from the electromagnetic inertia of the isolation transformer, the unit features excellent inrush current withstand capability, specially designed for industrial inductive loads such as motors, pumps and fans.
It continuously delivers purified pure sine-wave AC to critical loads.
Once mains power fails or voltage abnormality occurs, zero-time switching to battery power supply is realized to avoid power interruption.
The built-in isolation transformer provides galvanic isolation, suppresses grid surge, spike, harmonic interference and back electromotive force generated by motor loads.
It supports N+1 parallel redundancy, compatible with lead-acid and lithium iron phosphate batteries, ideal for harsh industrial power environments with heavy impact loads.
Typical Applications:
· Industrial pump, fan, compressor and other motor-type critical equipment power protection
· Chemical plant, oil refinery, mining, metallurgy workshop key control system backup power
· Water treatment station, pumping station, HVAC large motor control cabinet uninterrupted power supply
· Tunnel, underground pipe gallery, power substation industrial automation PLC & instrument power guarantee
· Manufacturing production line, CNC heavy machine tool, testing equipment power protection
· Large building fire control system, emergency motor equipment uninterrupted power supply
