Chroma 19070 Series Sentry Hipot Tester
No stress rentals! We help you to choose the equipment that you need, we expedite shipment, and follow up.
Application
- The Sentry 19070 Hipot Tester series provides 2 models to choose from. The Sentry 19071 for AC Hipot testing; and the Sentry 19073, which combines both AC and DC Hipot with insulation resistance (IR) measurements into a single compact unit.
Key features
- Hipot Tests: 0.05 ∼ 5 kV AC @ 0.1 ∼ 20 mA
- IR measurement: 1 MΩ ∼ 50 GΩ (19073)
- IGFI Shutdown when imbalance current > 0.5 mA
- Programmable ramp, fall, and test time
- Remote control and interface support
