Description

Fluke 393 FC CAT III 1500V True RMS AC/DC Clamp Meter for Solar PV Applications

The Fluke 393 FC CAT III 1500V True RMS AC/DC Clamp Meter is Fluke’s flagship clamp meter specifically engineered for solar photovoltaic (PV) systems, renewable energy installations, battery energy storage systems (BESS), and high-voltage DC applications. Designed for solar installers, PV commissioning engineers, renewable energy technicians, industrial maintenance professionals, utility engineers, electrical contractors, EPC companies, facility managers, and field service technicians, the Fluke 393 FC combines CAT III 1500V safety, True RMS accuracy, Fluke Connect® wireless technology, and advanced measurement capabilities into one rugged professional instrument.

As solar energy systems continue to evolve toward 1500V DC architectures, technicians require test equipment capable of safely measuring higher DC voltages while maintaining the highest levels of accuracy and operator protection. Traditional clamp meters designed for lower-voltage industrial applications often cannot meet the safety requirements of modern photovoltaic installations. The Fluke 393 FC has been purpose-built to address these challenges, making it one of the industry’s most capable clamp meters for utility-scale and commercial solar applications.

One of the most significant advantages of the Fluke 393 FC is its CAT III 1500V safety rating, allowing technicians to safely perform measurements on high-voltage DC solar arrays, combiner boxes, inverters, battery storage systems, DC disconnects, and photovoltaic distribution equipment. This industry-leading safety category provides confidence when working on next-generation solar installations where system voltages continue to increase to improve efficiency and reduce installation costs.

The Fluke 393 FC measures AC and DC current up to 999.9 Amps using its integrated clamp jaw, enabling non-contact current measurement without disconnecting energized conductors. This improves technician safety while minimizing downtime during inspections, commissioning, maintenance, and troubleshooting. For applications requiring higher current measurements, the clamp meter is compatible with the Fluke iFlex® Flexible Current Probe, extending AC current measurement capability up to 2000 Amps AC while allowing convenient access around large conductors, bundled cables, and confined installations.

The instrument utilizes True RMS technology, providing highly accurate measurements on both sinusoidal and distorted electrical waveforms. Modern renewable energy systems often incorporate advanced inverter technology, variable frequency drives, battery management systems, and sophisticated power electronics that generate harmonics and non-linear waveforms. True RMS capability ensures dependable measurement accuracy under these operating conditions.

Wireless communication through the Fluke Connect® platform enables technicians to monitor measurements remotely, automatically log inspection data, generate reports, analyze historical trends, and share results with maintenance teams. This wireless functionality enhances preventive maintenance programs, improves documentation accuracy, and allows technicians to remain outside hazardous electrical boundaries during live testing whenever practical.

Beyond current measurement, the Fluke 393 FC functions as a professional digital multimeter capable of measuring DC voltage up to 1500V, AC voltage up to 1000V, resistance, continuity, capacitance, frequency, and DC millivolts. These measurement capabilities allow technicians to perform complete commissioning, diagnostics, preventive maintenance, and troubleshooting using a single handheld instrument.

The clamp meter is particularly valuable for testing solar strings, combiner boxes, PV arrays, inverters, battery banks, charge controllers, electric vehicle charging infrastructure, DC distribution systems, renewable energy substations, industrial control panels, and commercial electrical installations.

Its thin clamp jaw design improves accessibility within crowded combiner boxes, inverter cabinets, battery enclosures, and electrical distribution panels where conventional clamp meters may be difficult to position. The lightweight ergonomic construction reduces operator fatigue during extended inspection and maintenance activities.

The Fluke 393 FC includes visual continuity testing, allowing technicians to verify electrical connections in noisy environments where audible continuity indicators may be difficult to hear. Additional productivity features include Data Hold, Min/Max recording, Automatic Power-Off, Auto Ranging, and a large backlit LCD display with clear digital readouts suitable for outdoor solar installations, electrical substations, industrial plants, and low-light maintenance environments.

Built for harsh outdoor conditions, the Fluke 393 FC features IP54-rated protection against dust ingress and water splashes, making it well suited for rooftop solar installations, utility-scale photovoltaic farms, renewable energy facilities, industrial plants, construction sites, and demanding field environments. The rugged impact-resistant housing ensures dependable long-term operation despite exposure to challenging weather and industrial conditions.

Safety remains at the core of Fluke’s engineering philosophy. In addition to its CAT III 1500V rating, the Fluke 393 FC is designed to comply with internationally recognized electrical safety standards, helping technicians safely diagnose energized PV systems, industrial electrical equipment, renewable energy infrastructure, and commercial power distribution networks.
