Darui Electric recommends for you
Frequency-modulated 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: 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, ensuring 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 resonance 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, step-up and step 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 resonance 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, step-up 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 modes: Touch screen and external mouse operation, with three running states: fully automatic, semi-automatic, and manual. It has functions such as voltage boosting, tuning (including manual and automatic), step-up and timing, running status, mode switching, fault indication, capacitance-inductance frequency interchange calculation, etc.
l Protection functions and information prompts: It has 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 results can be saved, printed, uploaded, and reviewed.
a. Test results: After manual or automatic test, the detailed parameters during the test can be displayed on the test result interface. When the test is interrupted, the interruption status can be prompted. The parameters can be saved in the memory, which is non-volatile and can store 50 test records.
b. Data query: Saved test result data can be displayed on the screen. It also has a USB interface for data output and printing, or printing via the printer carried by the device.
l Automatic voltage stabilization function: The system automatically tracks and maintains a stable test voltage based on the set test voltage or manual voltage boosting results, with voltage stability up to 1.5%.
l Frequency adjustment range and frequency resolution can be set: The frequency adjustment range can be set to 20～300Hz, 45～65Hz, 50Hz, or as needed, to speed up the tuning process; the frequency resolution can be preset to 0.1Hz, 0.2Hz, 1.0Hz, or 2.0Hz as needed, achieving an optimal balance between tuning efficiency and tuning accuracy.
Frequency adjustment is divided into coarse and fine adjustment, and can automatically find the test resonance point to ensure that the resonance frequency does not drift during the entire test.
