Frequency Tuning 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 hoisting. This ensures long-term stability and reliability of the variable frequency power supply.
l Parameter display: Touch 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, 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 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, staged voltage boost and timing, measurement 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.
