General details:
KWX-STS series
Static Transfer Switch (STS) of KWX series is a high-performance and cost-effective
third-generation fast load switching device designed by German debos technology in
combination with Europe's A-class load requirements. The device adopts the latest
DSP digital technology and the imported SCR module components, and adopts the
time-delay topological connection architecture to fully realize the precision of
switching time and perfect load transfer. KWX series static switch has high
performance protection, which improves the security and reliability of system
operation. Its harmonious LCD series interface design enables zero distance
communication between man and machine, and communication between PC and
RS232 port enables users to easily understand the operating conditions of STS. In line
with the concept of operation safety above all else, KWX series static switch is
undoubtedly the best choice for high-end customers in Europe.
KWX series static switch to alternative power automatic switch device, is to achieve
fast switching between two separate power supply non-contact electronic switch
device for digital equipment, control equipment or other high power equipment to
power supply continuity requirement to provide 100% of the power supply security of
highly reliable utilization, when all the power overrun or blackout, quickly switch to
another power supply, ensure the data security and equipment operation. It is a
powerful tool for implementing so-called "distributed power supply" schemes, which
can greatly improve the reliability of power supply systems.
KWX series static switch is mainly composed of intelligent control board, high speed
SCR, circuit breaker, the Break before make sense (Break before Conduct) switching
mode, its standard switch time for 4 ms or less, load power, won't cause IT to load
and reliable power supply, at the same time can guarantee the security of DPS in
different phase when switching to a single power supply load with double bus power
supply scheme selection,such as:
■N +1 redundancy in non-parallel UPS systems
■N +1 redundancy of UPS systems with different capacities
■N +1 redundancy in different types of UPS systems.
■Redundancy of different utilities
■Power supply and redundancy of UPS
■Redundancy of generator and UPS

General Range Details.
Main functions:
- Automatic switching function
■Intelligent switching: at any time, when the power in one line is cut off (including
manual switching), the device will automatically switch to the other line, avoiding the
danger of manual switching or power cutting.
■Switching between high and low voltage protection: when ac low voltage or
overvoltage is input in one line, the device will automatically switch to the power
supply in the other line.
■Intelligent timing switch (optional module) : it can set the power supply time of one
circuit and automatically switch to the other circuit to ensure the aging degree of
power supply of two circuits and extend the service life.
☆Manual switching function:
■When the two power sources are normal, the load can be transferred to the other
power supply through the panel control button.
■Power supply priority: can be set by the user, the system default I power supply
priority.
■STS machine failure, manual repair bypass.
☆Protection function:
■Overload protection: when the load exceeds 100%-125% of the load of the
equipment for 30 minutes continuously, 125%-150% for 20 seconds continuously,
150%-300% for 2 seconds continuously, the equipment will automatically shut off the
output and alarm, and automatically open again after 10 seconds.
■When the power is cut off or exceeds the limit, the device will automatically lock
and switch manually and automatically.
-Intelligent alarm function:
■When the power is cut off, the device will start the alarm automatically, and the
sound will be silenced automatically after 90 seconds.
■When the power exceeds the limit, the equipment automatically starts the alarm,90
seconds after the automatic noise.
■Self-check function, the machine fails, the equipment starts the alarm
automatically,90 seconds after the automatic muffling.
☆Monitoring function:
■LED display: working status (one or two working, one abnormal or two abnormal
and output fault).
■LCD display: a large-screen LCD display is used to display the operating status of
STS: input voltage parameters, output voltage parameters, output current parameters,
working status (working in one or two ways, abnormal in one way or abnormal in two
ways, and output fault), so as to realize zero-distance communication between man
and machine.
■RS232/RS485 remote communication interface: it is used for the communication
between STS and PC, so that users can understand the operation condition of STS
remotely and directly operate STS on PC.
Technical advantages:
■Adopting the high-speed intelligent sampling module and synchronous control
technology, the unique precise calculation of the four-level Fourier function and the
industrial level hardware circuit board three-prevention process design, the perfect
load transfer is realized.
■The time-delay topology architecture is adopted to ensure reliable access through
intermittent switching. The standard switching time is ≤4ms and the minimum
switching time is 0ms(equipotential), which truly achieves the accuracy of switching.
■Super power adaptability: can simultaneously input the same phase and different
phase of the power situation.
■High quality components: international brand SCR and DSP module, with strong
overload and impact resistance.
■Ultrawide range of municipal power input (voltage and frequency), the solution of
the severe changes in municipal power caused by the trouble.
■Single-phase 1U series adopts the standard IEC320 output interface, which is
convenient to connect the PDU insert row.
■Single-phase series 1U/2U/3U international standard frame structure design,
convenient for user transformation, maintenance without power.
■TPT series can work normally under the condition of 100% three-phase unbalanced
load.
■Mean fail-free time（MTBF）：200000h。
■Digital circulation control technology, multiple connections can be combined into
n+1=1 output, simple capacity expansion of STS, enhance the reliability of power
supply.
■Power consumption: no more than 2%;
■Heat dissipation: air cooling.
