Frequency Conversion Series Resonance Test Device
l Input voltage: Three-phase 380V±5% or single-phase 220V±5% 45～65Hz. When the power supply is 380V, rated load test can be performed; when the power supply is 220V, only 1/2 load test can be performed.
l Output voltage: 0～400V adjustable
l Output voltage frequency: 20～300Hz
l Frequency adjustment: 0.1Hz step adjustable
l Frequency instability: ≤0.02%
l Output current: 0～30A
Performance features: l Placement method: The variable frequency power supply can be placed vertically and horizontally, especially suitable for on-site operation and observation.
l Shockproof protection: Internal and external special shock-absorbing rubber support feet and protective aluminum box effectively reduce vibration during transportation and impact during lifting. This ensures long-term stability and reliability of the variable frequency power supply.
l Parameter display: Touch screen or external mouse large-screen LCD interface display system.
It can display resonant voltage (i.e., target voltage set before test), test frequency, measured frequency, low-voltage voltage, low-voltage current, withstand voltage time, overvoltage protection, overcurrent protection, flashover protection, staged voltage boost and timing, operation mode switching, capacitance, inductance, frequency interchange calculation, parameter query, etc. It can also display frequency curves, voltage curves, etc., to intuitively judge the accuracy and stability of the resonant frequency of the current test.
l Parameter setting: Large-screen touch LCD color screen and external mouse directly complete various parameter settings. Parameters such as start frequency, end frequency, start voltage, staged voltage boost and timing, voltage divider ratio, excitation transformer ratio, overvoltage protection, overcurrent protection, flashover protection, test mode, capacitance-inductance frequency interchange calculation, parameter setting prompts, and help can be set or selected.
l Test mode: Touch screen and external mouse operation, with three running states: fully automatic, semi-automatic, and manual. It has functions such as voltage boost, tuning (including manual and automatic), staged voltage application and timing, running status, mode switching, fault indication, capacitance-inductance frequency interchange calculation, etc.
l Protection functions and information prompts: Equipped with multiple protection functions such as high-voltage overvoltage protection, low-voltage overcurrent, overcurrent protection, detuning protection, zero position, flashover protection, emergency stop, undervoltage protection, etc.
l Data storage function: Test result saving, printing, uploading, and recall.
a. Test results: After manual or automatic test completion, series resonance withstand voltage equipment can display detailed parameters of the test in the test result interface. When the test is interrupted, the interruption status can be indicated. The parameters can be saved in the memory, which is non-volatile and can save 50 test records.
