20kVA Low Frequency Online UPS

Double-conversion online topology design makes the UPS pure sine wave output with frequency tracking, phase-locking, voltage regulator and filter out noise, interference from the power grid fluctuations, and makes the UPS provide more comprehensive and perfect protection for users.

Whale series UPS equipped with standard built- in output isolation transformers, static bypass switch and manual maintain switch makes this series UPS have strong short-circuit protection capacity for worst application; Also it has perfect protection: AC input, over-voltage, under-voltage, output over-voltage, short circuit protection over temperature and etc…

Whale series UPS include 3in/1out(8k-100k), 3in/3out(6k-200k), which can be in parallel with 8 units UPS directly, conveniently and fast. Flexible parallel technology could be applied to different loads and systems.

Function features
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, out 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 RS 232 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 u
