Single Phase Kwh/Energy Meter Test Bench 48 Postion 0.05% Accurancy¹

Product Description IntroductionKP-S1000 single phase energy auto-calibration system is a newgeneration, high precision energy meter calibration equipment. It uses the advanced technology and electronic components available in 90 decade . The test bench can be operated from embedded keyboard or operated from PC software. Feature and function1) Equipped with electronic phantom load power source, assuring high stability,security and large output capacity.2)Automatic adjustment of current measurement range. Fault self-detection in voltage amplifier and current amplifier.3) Equipped with RS-232C interface, can be operated from software.4) Test results be saved to database, can be inquired from database and can be printed out. Technical SpecificationsPower supply: 220V+10%, 50Hz/60HzMaximum power consumption: 1000VA (for 24 positions) Power source Technical specification:Voltage output: 1x 30V (AC) - 1 x 300V (AC);Resolving power: 0.01% of current rangeCurrent output: 0.001A (AC) - 100A (AC)Resolving power: 0.01% of current range (min 0.0001A)Phase shift range: 0-360°Resolving power: 0.1°Frequency output: 45Hz - 65HzResolving power: 0.01HzWaveform distortion (sine wave output):voltage < 0.5%current < 0.5%Stability of power source (sine wave output):< 0.1% (180s)Load can be resistance / inductor or capacitance(<4uF)Output waveform: sine waveformOutput capacity:Voltage source: 300VA-1500VA(dependent on meter positions)Current source: 300VA-2500VA(dependent on meter positions) Reference meter Technical specificationType: KP-1100 reference meter (compatible HY5101or HDS122-02 )Power supply: 220V +10%, 50Hz/60HzMaximum power consumption: 20VAMeasurement range:Voltage: 60V (AC) - 280V (AC)Current: 0A (AC) - 100.0 (AC)Accuracy: 0.1Warming up: 1 minsWorking environment:Temperature: + 5oC~ + 40oCRelative humidity<85%Dimensions: 480mm X 420mm X 140mmWeight: 2.0kg Error Calculator Technical specificationImpulse of tested meter could be: TTL / OC / Optical headMax. frequency of impulse could be: 200HzError display range: 0.001%-99.99%Introduction:1.Signal generatorThe "YELLOW COLOR" marked frame is included in signal generator box. Signalgenerator is equipped with DDS waveform technology (digital frequencymodulation, amplitude modulation and phase modulation). Embedded MCU isthe brain of signal generator, also it is the brain of testbench, signal generatorgenerate high stability sine waveform which is send to voltage amplifier andcurrent amplifier.2. Power amplifierPower amplifier features stability and reliability with the PWM amplifytechnology and well-designed protection when output voltage shortcut andoutput current circuit open.3.MeasurementError of tested meter is achieved by comparison with the reference meter.
