Low frequency True sine wave online ups 50kva

Low frequency online ups backup power supply for industry, telecom 30KVA 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. After Prostar R&D center elaborative designed for more than 10 yeas, Prostar has designed a modular structure, whose overall operation is 5 times more reliable and stable performance than regular UPS, MTBF is over 300,000 hours.

Low frequency online ups backup power supply for industry, telecom 30KVA equipped with standard built-output isolation transformers, static bypass switch and manual maintain switch, making this series UPS has a very high capacity to engage in short-circuit. It could be used for the worst environment. Also it has perfect protect function.Moreover, it has the AC input, over-voltage, under-voltage, output over-voltage, short circuit protection, inverter, rectifier over-temperature protection, voltage under-voltage warning, battery over charging protection and other protections in one, to ensure system operation stably and reliably.

1) DSP digital control technology

Core system uses the world's most advanced all-digital DSP control technology, which can effectively guarantee the UPS' core system accurate, and fast running.

2) Advanced IGBT inverter technology

Combined high-reliable and high-efficiency IGBT inverter technology with high-frequency Pulse Width Modulation technology (PWM).     
It could reduce noise and power loss, to ensure users can load in a variety of working situations and obtain high-quality voltage output and maximum cost-effectiveness, but also make input efficiency more than 95%.
 
3) Pure-online double conversion technology
Reliable and stable, after filtered and regulated, the output sine wave from pure-online double conversion technology, not only has the atmospheric disturbance suppression filter, but also with the standard output isolation transformers, static bypass, maintenance bypass, make this product with higher ability to engage in short circuit current. And it can be applied to the worst working environment.
 
4) Perfect protection
Perfectly system protection functions: It has AC over-voltage, under-voltage, output over-voltage, under-voltage, output overload, short circuit protection, inverter, rectifier over-temperature protection, voltage under-voltage warning, battery over charging protection and other protections in one to ensure the system to operate stably and reliably.

5) Powerful Redundant Parallel Connection Function
Durable and reliable design of industrial-type modular structure, combined with full digital DSP control technology core system, make this product not only can be used for N +1 / N + X redundancy and the ability of enlarge the capacity, but also permit different power and different times of the UPS could be in parallel. It greatly reduced the user's pre-and post-purchasing costs, and increased capacity costs, but also expanded upper spaces of increasing capacity.
 
6) Powerful communication system
The standard equipped with RS232 interface, do contact relays, emergency switching device EPO input interface.
 
7) Low-power dissipation but high-efficiency
To achieve more than 98% of ultra-high efficiency under ECO economic model, which can effectively bring down the amount of electricity, and effective in accordance with the requirements of energy-saving target of the country.

 
8) Prediction warning system
LCD panel automatic detection function and timely warning in advance, with the boot self-diagnosis function. It could avoid the hidden danger in time due to UPS' failure, which caused risks. Also it could automatically alarm by setting the battery discharge to standby time is less than a set value.
 
9) Humanized panel display
Humanized panel settings, the users can set system parameters, date, output voltage, battery capacity, alarm function, light-load shutdown, system boot time, MODEM settings, such as orders, also it can be up to 120 abnormal failure information for users to query.
 
10) Super-strong environment adaptability
This product has superior environmental adaptability, wide AC input range, greatly reduces the frequency of battery using, and effectively extends the battery life.

11) Powerful Overload Ability
Using the pure-online double conversion technology, with the output isolation transformers, static bypass, and maintenance bypass.
Inverter Overload Ability reached 110% / 125% / 150% overloading time can last for 300min/10min/1min.
Bypass Overload Ability reached 150% / 170% / 250% overloading time can last for 60min/10min/1min.
