Load box products, identify the Guangluda brand, 5000 ㎡ production workshop, complete qualification certificates, strong strength, long-term safe and stable operation of the products, low noise, we Guangluda to provide 10 years of after-sales service, so that you can buy at ease.

Load box function introduction:

1. Can measure the generator steady-state three-phase voltage, current, frequency, running time and other basic functions.

2. With harmonic analysis function, can simultaneously analyze the voltage, current 2~50 harmonic content and total harmonic content; power accumulation function.

3. With powerful voltage recording function, and equipped with photoelectric isolation RS485/RS232 serial communication function, serial port function is powerful.

4. Not only can all steady-state parameters be called and measured, but also sudden addition, sudden unloading, voltage, current and frequency curves, voltage and current harmonic curves and harmonic content can be called and measured.

5. Load control function, can complete the load sudden, sudden unloading function.

6. Optimize the segmented power input mode and easy to set up.

7. Can realize manual control loading and unloading on the remote panel.

Load box application areas:

load detection of generator set, high-power power supply and power station.

Load box test function

1. Steady-state measurement: three-phase voltage, three-phase current, active power, reactive power, apparent power, power factor, frequency, power running time, voltage imbalance

2. Band load function: it can realize automatic loading and unloading functions from 0%, 25%, 50%, 75%, 100, 110 and other power segments

3. Sudden and sudden unloading test: can capture transient voltage, maximum frequency, minimum current and recovery time

4. Setting test: can capture the voltage, frequency setting maximum value, minimum value, can calculate the relative voltage, frequency setting rise, fall range and adjustment rate

5. Volatility test: can capture the maximum and minimum values of voltage and frequency fluctuations, and can calculate the steady-state frequency band, steady-state voltage deviation, voltage modulation, fluctuation rate and frequency.

6. Harmonic analysis: 2-50 harmonics, and its total harmonics; recording 5 modes to record the voltage real-time waveform, recording time 5 seconds to 5 minutes
