    High Precision Energy Meter Calibration Equipment For Distribution Network Terminal Test

    1. Function Description

    1) High-precision programmable voltage and current output, amplitude, phase and frequency are arbitrarily adjustable
    2) Support state sequence output mode, state switching delay is less than 100uS
    3) Support the trigger signal, start the output when the trigger pulse arrives, and the trigger delay is less than or equal to 100us
    4) Support multiple devices to synchronize output synchronously under the synchronization signal, and use GPS second pulse signal to achieve long-distance synchronization
    5) Support recording playback function
    6) The multi-phase currents are isolated from each other and can be output in parallel. The total output current is the vector sum of the multi-phase outputs. The total current can be obtained by setting the phase to the same phase.
    7) Note: Multi-phase voltages are not isolated and cannot be used in series or in parallel. In severe cases, the equipment will be burnt.

    2. Application field

    Distribution network terminal test, transformer test, electric energy meter test, etc. where large output power and output current are required

    3. Main features of the product

    1) It is possible to output a pure sinusoidal power signal with a distortion of 0.05% (typical).
    2) The frequency output can be adjusted from 40Hz to 100Hz, the resolution is 0.001Hz, and the accuracy is 0.002Hz.
    3) Each phase frequency is individually adjustable, so it can be phase-separated.
    4) The phase 0~360 degrees can be adjusted arbitrarily, which can easily simulate various power supply situations and even reverse power transmission.
    5) Strong load capacity, full load capacity, inductive, resistive load or composite type load, and the load regulation rate is better than 0.05% RG.
    6) Excellent temperature stability, the core device is a military grade product with a temperature coefficient as small as 1PPM, which can guarantee the output precision in the outdoor temperature environment.
    7) It is powerful and flexible with 32-bit MCU+DSP processor.
    8) The waveform of the power frequency is up to 50,000 points per week, and the internal signal output is smoothed without filters. It ensures the accurate output of the waveform, making the output of higher harmonics possible, and the system has excellent harmonic distortion. Degree indicator.
    9) It has RJ45 network port and RS232 port for convenient connection with PC or secondary development.
    10) Improve the protection function.
    11) Hardware PID, response time is less than 100us.
    12) Typical load regulation is less than one in ten thousand.
    13) The main control module + expansion module combination structure can be easily combined into a 1~4 phase test system.
    14) Multiphase currents can be connected in parallel to obtain a large current output.
    15) Provide multi-platform protocol library interface to facilitate secondary development of users. The specific development platform is welcome to call us.
