Overview
The LS-RVT Series Residual Voltage Tester (Peak Power Cutoff Device) detects residual voltage in electrical equipment by disconnecting the tested equipment from mains voltage at the voltage peak, maintaining high insulation resistance after disconnection to simulate a plug being pulled out. The instrument measures residual voltage after power failure, supports multiple cyclic tests, automatically records and calculates statistics, and triggers sound/light alarms with voltage cutoff when readings exceed set limits.
Three power tiers are available: LS-RVT-2000W (2000W/10A single-phase), LS-RVT-4000W (4000W/16A single-phase) and LS-RVT-5000W-3P (5000W/7.5A three-phase, up to 380V).
Key Specifications
Output voltage: AC 0-242V (single-phase models), AC 0-380V (3-phase model) | Residual voltage range: 5-300.0V, accuracy ±(reading*1%+1V) | Testing time: 1-99s | Testing impedance: ≥100MΩ | Communication: RS-485 (optional)
Features
- Disconnects EUT from mains at voltage peak to simulate plug removal
