Function & Advantage
Clear, Intuitive, Convenient, Humanized
Adopting a new generation of human-machine control interface, paired with a full touch panel design, a simple Ul operation interface, combined with a rotary knob design to easily complete parameter settings and professional programming functions, supporting USB data loading and unloading on the front panel. The entire series of products support the front panel flipping function, makingit easy to operate anduse.
Global Input Voltage to Meet Different Test Environments
This series of power supply is configured with multiple input phase options, which can meet the single-phase:100~132VLN/187~ 300VLN, three-phase:187~300VLL/340~460VLL and other electrical environments, some models support single/three-phase input at the same time, can be used in any electrical system range.
Industry technology frontier, Fiber High-Speed Parallel
When there is a higher power demand, the master-slave parallel function can be used to improve the output current and powercapacity, and up to 64 single units can be realized in parallel up to 768kVA. The parallel machine adopts optical fiber high-speedcommunication capability to achieve near-zero transmission delay, which ensures the synchronization of the parallel machineand ensures the synchronous flow sharing output of multiple modules. It supports synchronization of all functions withoutperformance degradation, and perfectly presents the operating experience as a stand-alone test.
*650W Units is not support this function.
Multi Channel Test Function
This series can meet the testing requirements of up to three channels without additional configuration. Parameters can be set independently and output can be controlled. At the same time, synchronous/delay output can be set according to testing requirements. If you purchase an MST420VAC6000W, it is equivalent to obtaining three additional single-phase 2000W models. One machine for multiple uses, with extremely high cost performance.
* MS series do not support this function.
Seamless Voltage Transition, Current Multiplication Output
Seamless transition of voltage gears reduce the impact on output when switching voltage gears. Up to 2 times current output on the basis of traditional rated current. When the voltage is reduced from the rated value to 50%, the technology linearl yincreases the output current to twice the current corresponding to the rated voltage, while ensuring full power output over the widest voltage range. This eliminates the need for users to purchase overpowered power supplies to meet high current demands.
Diversified Output Modes for Easy One Click Switching
The three coupling modes of AC, DC, and AC+DC can not only achieve stable AC/DC output, but also cover experiments such as AC signal superimposed DC bias and ripple injection through the AC+DC output mode.
Support single-phase, three-phase, reverse phase, multi-channel output mode. Support Y-type/Delta type wiring mode in three-phase mode, can simulate three-phase unbalance, three-phase harmonic unbalance, phase missing, phase sequence reverse connection and other tests. The reverse phase mode can provide up to twice the output voltage, and the multi-channel mode meets the independent testing of up to three single phase objects simultaneously.
Power Line Disturbance Function(PLD)
This series of power supply provides multiple waveform editing modes to simulate various power grid interference conditions and regulatory certification projects, such as periodic power outages, dips, instantaneous spikes, or more complex waveform outputs. It is widely used in research and development laboratories, universities, and certification laboratories.
Voltage and Frequency Output Variable Rate is Adjustable
The output voltage can reach 820V, and the output frequency range is 10~5000Hz. The soft start of voltage and frequency can be achieved by slope setting, effectively reducing the surge current generated when the motor or compressor is started.
*Professional Version/Advanced Version:10~2500Hz; Professional-HF Version:10~5000Hz
Built-in High Precision Power Meter
It can measure 24 electrical parameters, accurately and quickly view the real-time data of each data value, open custom display sorting, easy to grasp the condition of the object to be measured, no need to connect complex lines and additional power meters, saving test time and equipment costs.
Harmonic/Inter-harmonic Generation Simulation and Measurement Function
Support waveform synthesis editing, harmonic components up to 50 orders, base frequency of 50Hz or 60Hz. It supports the synthesis and editing of interharmonics, and superposes another voltage component with variable frequency on the original basic voltage output, which is suitable for anti-interference simulation test. Supports the measurement of total harmonic distortion (THD) at 50Hz or 60Hz base frequency, DC current, output current and output voltage base frequency. It can measure the amplitude of 2 to 50 harmonics or the percentage based on the fundamental frequency voltage, and can graphically preview the distribution of harmonic components.
Programmable Output Impedance Function
The low output impedance and low voltage harmonics of this series of power supply makes it conform to lEC61000-3-2 standard, and provide programmable output impedance function, the output voltage is controlled by the load current feedback circuit, which can be suitable for IEC61000-3-3 standard test. Users can set output resistance and inductance parameters according to test requirements to simulate specific test conditions.
DDS Arbitrary Function Generator
This series of power supply has built-in triangular wave, rectangular wave, trapezoidal wave, DIN40839 and ISO-16750-2 and other typical waveform setting interface, which is convenient for customers to edit and call. In addition to the above standard functions, you can also edit the output of any complex functions that can be used for research and development and production tests.
