Product Description
Test function
1. Steady state measurement: three-phase voltage, three-phase current, active power, reactive power, apparent power, power factor, frequency, electric energy operation time, voltage unbalance
2. Band load function: it can realize automatic loading and unloading functions from 0%, 25%, 50%, 75%, 100%, 110% and other power bands
3. Sudden loading and unloading test: can capture transient voltage, maximum frequency, minimum current and recovery time
4. Setting test: can capture the maximum and minimum values of voltage and frequency setting, and can calculate the relative voltage and frequency setting rise and fall range and adjustment rate
5. Fluctuation 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 their total harmonics; Record voltage real-time waveform in five modes, with recording time of 5 seconds to 5 minutes
control mode
MODE1, touch screen manual and automatic control
MODE2, computer software control (using WENSHIN load intelligent test software control)
MODE3, RS485 communication (provide MODBUS RTU communication protocol to meet automatic integration test) (default is local touch screen control, users can choose MDE2 or MODE3)
Loading method
Steady state load: preset a test value and test time, and carry out load test according to the set value
Transient load: preset a test value to complete sudden load and sudden load unloading test
Band loading: preset multiple test values and test time, and automatically carry out load test according to the set process
Automatic power compensation
The system automatically tracks the online test power and realizes high-precision load test through program automatic compensation
Automatic start and stop of fan
After the test, the fan will keep running, and the fan will shut down automatically after the equipment is preheated.
Automatic speed regulation of fan
The test power value of fan fan automatically adjusts the air volume to make the low power test more silent
Protection function
Overvoltage, fan fault, overtemperature protection, short circuit protection, phase sequence protection
Data storage function
The system can record online test voltage, current, power and other parameters, and the test data can be stored in EXCEL table, which can be exported through USB flash disk for in-depth analysis.
Expansion interface
MODBUS RTU RS485, RS232, Ethernet port, CAN (default 485, optional according to requirements)
