Product Description
1KVA to 10KVA online double conversion switching power supply 


Product description: 
ESD Series UPS is adopting the technology, which combined with the world's most advanced DSP digital control technology currently, and IGBT high frequency Pulse Width Modulation technique (PWM). Double-conversion online topology design makes the output frequency of UPS, which used for tracking, phase-locking, voltage regulator and filter out noise, interference from the power grid fluctuations in pure sine wave power supply, and make the UPS more comprehensive and perfectly protection for the users.




1. High charging capability
2. Cold start and mains start function
3. Standard configuration with output isolation transformer
4. Suitable for all kinds of loads (resistive, inductive and non-linear loads etc)
5. Other options(parallel kits, input isolation transformer, bypass isolation transformer and harmonic suppressor)
6. High overload capability (up to 150%)
7. DSP (Digital Signal Processors) technology
8. Bypass dual DSP control design to enhance more reliability
9. Single / single-phase models with on-line double conversion technology
10. Advanced communications RS232 and USB ports (standard), SNMP, dry contacts and RS485 (options)
11. Superior protection (surge, short-circuit, over-voltage, undervoltages, overcharge, overload, over temperature, reverse connection protection etc.)
