High-voltage hipot tester UHV-285

portableAC

Product Introduction
The UHV-285 portable AC withstand-voltage (Hipot) tester performs on-site dielectric withstand tests by applying controlled AC high voltage to electrical equipment while monitoring leakage current to verify insulation integrity and compliance with safety requirements.

Product functions

• Precise leakage-current measurement: real-time monitoring and automatic pass/fail evaluation against programmable limits.
• Adjustable alarm threshold with high-precision sampling: user-set alarm current triggers audible/visual alarm and HV shut-off on exceedance.
• Multiple protections: built-in overcurrent, leakage-current limit and high-voltage output-abnormality protections with fast automatic response.

Product features

• High-brightness digital display with wide viewing angle for clear readout.
• Real-time display of leakage current and test voltage during operation.
• Preset timer with countdown and automatic output cut-off at timeout for safe interruption.
• 50 Hz sine-wave output with stable waveform quality.
• Critical components use imported parts to support measurement accuracy and service life.
• Compact one-piece chassis for field portability; output power 1000 VA.
