Industrial Uninterruptible Power 250kva Three-Phase Online UPS With IGBT

Product Specification

Industrial ups 250kva ups power generator 250kva Three-phase Online UPS with IGBT, Output Transformer

Basic Features :

With dual conversion true online design and digital technology, this kind of UPS has perfect protection and high reliability.

1. Inverter adopts DSP, MCU and DDC digital vector control technology to commend each specification and control them completely.

2. Integrating advanced IGBT and PWM to decrease the system noise and wastage of the electric power and to make sure customers can obtain high-quality output voltage and the upmost benefit under various loads.

3. Due to dual conversion and pure online sine wave output, the UPS can provide low distortion and pure sine wave power supply and the optimal power guarantee for the users' load devices both on main mode and battery mode.

4. It is with output isolation transformer to ensure the load and public electricity to be isolated completely. There is no DC in the load for the UPS with isolation transformer, which can effectively protect computer, network, and communication devices from damaging of DC. Besides, for the nonlinear load, it can improve the load capability of the machine and with good compatibility.

5. Automatic frequency /corresponding synchronous function avoid skipping frequency to influence the devices.

6. With perfect protections: AC input low and over voltage protections, output low and over voltage protections, output overload and short circuit protections, low battery protection, and over temperature inner of machine protection to ensure the stability and reliability of the system running.

7. Using the big power IGBT makes the inverter with the strong ability of overload and resistant impact, and enhances the adaptation to the electric environment.

Flexible parallel technology is fit for various loads, 1+1 parallel, N+1 parallel running;

Each UPS in parallel is working alone and synchronous track will be adjusted to optimality ( phasic difference less than 0.50 ). The UPS can Share the load precisely and when the inverter break down, the failure UPS will shut off automatically from the parallel system to ensure that the parallel system can provide high quality AC power supply to the load. The circumfluence of the parallel system is almost zero and current imbalance is less than 2%.

Multi-UPS parallel system: It allows the users to parallel 8 pieces of UPS at the most. Advanced monitor and DSP digital control technology makes the parallel system as easy as unit UPS and all the UPS are equal, no primary and secondary relation and it's the true equality. If you have bought one similar unit of UPS, when you need to increase the capacity or enhance the reliability, you can extend it to '1+1' parallel system easily and can continue to extend it to N+X multi-UPS system.

System is through strict tests of short circuit and 2KVA high voltage isolation.

Full digital control technology makes the whole unit more precise, prompt, reliable and stable.

Strong intelligent monitor function can provide RS232, dry contact and parallel interface.

UPS power supply environment monitor system, with the international advanced technology, develops intelligent unit and monitor management software and provides users with professional, complete, practical and reliable power monitor project, which enable the intelligent network to manage the UPS system promptly and reliably. UPS convergent monitor managing software can control the UPS everywhere in the world and inform a huge UPS power network monitor managing system.

Monitor software features:

1. Face single user real-time monitoring;

2. Face large-scale WAN centralized management real-time monitoring.

Choosing 12 impulses to correct input power factor effectively and restrain the pollution caused by UPS.
