EK-M Series Multiformat Modular UPS
Introduction: EK-M Series combines a modular, hot-swappable, multi-standard,
distributed logic, parallel, touch-screen operation, etc. the
industry"s most advanced technology, first used in the inverter
structure of the "multi-level inverter" concept, ingenious The
adoption of the four half-bridge driver circuit topology, the use
of digital signal processor (DSP) control algorithm with the
original completed the three-phase sine wave inverter function. Compared with the conventional inverter power devices of its loss
can be reduced at the end of twice the output voltage of high-order
harmonic reduction nearly doubled, thereby reducing the size,
increases the power density. Products in the UPS industry, the first use of a 32-bit digital
signal processor as the core processing chip, the chip is currently
the international market, the most advanced and most powerful
32-bit DSP processor. Running at speeds up to 150MPS, both with a
strong numerical computing power, but also has extensive event
management capabilities. Particularly suitable for dealing with complex, high-precision,
high-speed, real-time requirement is very control system. It used
to make the product in terms of electrical performance,
reliability, functionality and other areas have the greatest degree
of increase. Features: Work with a variety of formats The product has a variety of formats to choose from, and users do
not need the machine to perform complicated operation, just toggle
switch on the side of the body motivated to complete the standard
choice. Concrete can be realized: three-phase input three-phase
output, single-phase input single phase output, three-phase input
single phase output, single-phase input three-phase output, input
frequency can be set for 50Hz output frequency 60Hz, the output
voltage can be set to 220V , 230V, 240V. Ruozai configuration input, output transformer can meet the global
scope of all countries and regions, demand for electricity supply. Small size, power density, The product is high efficiency, power density, is its greatest
feature. A power module size: 482.6mm (W)88.1mm (high)470mm (D) (ie
the standard 19-inch 2U height) can provide 10KVA (8000W) power
output. Input power factor high on the grid harmonic pollution produced by
a small Adopted the three-phase power factor corrected technology that
enables a small 5% input harmonic current, input power factor of
0.99 or above. Reduce line losses, improve power efficiency. machine, high efficiency, with energy-saving, energy-saving and so
on In the UPS industry has given priority to the three-level inverter,
the inverter efficiency is above 98%, thus increasing machine
efficiency, reduces wear and tear, saving power. Modular structure design, easy installation, maintenance,
replacement, upgrades The models by the various modules, and the size of each module in
accordance with standard 19-inch structural design, so that machine
in line shape with the standard rack and beautify the machine
appearance, and the module can be common with the standard rack. Touch-screen mode of operation UPS showed that some use of touch screen mode of operation, has
shown an intuitive, simple operation, easy to use and so on. Distributed Parallel Logic Control Parallel control between the various modules using distributed
logic control method, there is no master and slave of the points
allocated to any one module or insert other modules will not affect
the normal operation so as to enhance the reliability of the
machine work, also simplifies the user maintenance more difficult. Module supports hot-swapping of work UPS module, display control module can achieve the hot-swapping
function, convenient for users to replace the module, and each
module rack can be completely separated, user-friendly future
expansion or volume reduction, use very convenient. Change can be
realized online, on-line maintenance, reducing maintenance
difficulty, reducing maintenance time. Intelligent charging In the external battery when the UPS can be automatically or
manually through the touch to set the maximum charge current, the
first single modules to provide maximum charge current of 10A, the
configuration time-lapse machine without an external charger. Full Digital Control The three most of the machine are used in DSP digital processing
chip to achieve digital control of the product, thus ensuring the
stability of the whole system, and dependability. Main technical parameters: |
