currenttemperaturevoltage

Product Introduction:
The UHV-316C motor comprehensive test bench is designed for factory inspection of single‑phase and three‑phase small and medium asynchronous motors. The bench includes an integrated variable‑frequency test power supply and supports the following main tests:

• DC resistance test
• Insulation resistance test
• Surge (inter‑turn) test
• Electrical parameter measurement (voltage, current, frequency)
• Power‑frequency withstand voltage test

Product Characteristics:

• Real‑time result display with on‑board data storage and print recording for traceability
• Standard parameter storage enabling automatic pass/fail comparison against saved motor profiles
• Multi‑motor simultaneous testing to increase throughput in production environments
• Accurate and fast measurements with robust anti‑interference design and intuitive operation
• Windows‑based automatic judgment and modular hardware architecture to simplify maintenance and calibration

Product Parameters:

• Temperature: -40 to 150 °C, accuracy ±1 °C (ambient temperature measurement)
• DC resistance: 0.01–2000 Ω, Class 0.2; 6 measuring ranges with automatic temperature compensation
• Insulation resistance: DC 500 V, 1–500 MΩ, Class 5.0; automatic background deduction
• Inter‑turn (surge) test: 400–3000 Vp, Class 5.0; wavefront time 0.2 μs; adjacency detection to 1/200 turns
• Power‑frequency withstand voltage: AC 400–3000 V, Class 2.0; test duration selectable 1–60 s; leakage current 1–100 mA with automatic background deduction and breakdown protection
• Electrical parameter test: Current ranges 0.1–50 A and 50–200 A (Class 0.5); Voltage 30–750 V (Class 0.5); Frequency 50/60 Hz (asynchronous)
