OverviewThe Fluke 393 FC CAT III 1500 V True-rms Solar Clamp Meter with iFlex is engineered for PV installers and maintenance technicians working in high-voltage DC environments such as photovoltaic arrays, wind farms, electric railways, data centers and battery banks. It measures up to 1500 V DC and 1000 V AC with test leads, and up to 999.9 A DC or AC via the clamp jaw. The supplied iFlex flexible current probe extends AC current measurement capability up to 2500 A. A thin jaw profile provides access in crowded combiner boxes; test leads are rated CAT III 1500 V DC.
Key features- Safety rating: CAT III 1500 V for measurements in high-voltage DC systems
- Thin jaw (34 mm) for access in compact combiner boxes
- IP54 ingress protection for outdoor use on PV and wind installations
- DC power measurement with display in kVA for solar inspections
- Audio polarity indicator to reduce wiring errors
- Visual continuity indication (bright green display) for noisy or dark environments
- Data logging and reporting via Fluke Connect
