High-voltage hipot tester UHV-316N

DCACelectrical conformity

Product Introduction
The UHV-316N Intelligent Power-Frequency Withstand Voltage Tester is designed for power-frequency dielectric strength testing of single-phase and three-phase AC/DC motors, transformers and electrical coils. The instrument meets applicable national and industry technical requirements. It offers comprehensive functions, straightforward operation and built-in safety protections. Output voltage and capacity can be customized for special requirements.

Product Features

• User interface: Color LCD touch screen with guided prompts and self-diagnosis for intuitive operation.
• Parameter storage: Multiple storage groups to save distinct test parameter sets and results.
• Real-time monitoring: Live display of measured values and real-time curves for voltage and leakage current.
• Voltage regulation & protection: Electronic voltage regulation with comprehensive overvoltage protection.
• Preset & stable output: Preset output voltage and an approaching-regulation algorithm that maintains stable voltage during timing.
• Overcurrent protection: Audible/visual alarm, automatic high-voltage cutoff and regulator reset if leakage current exceeds the set threshold.
• Grounding detection: Real-time grounding protection that prohibits or terminates tests when grounding is unreliable.
• Integrated printer: Built-in micro printer for immediate printing of stored test data and results.
