Specialized Solar Energy Diagnostics: MESTEK CM86C High-Voltage Photovoltaic (PV) Digital Clamp Meter in Malaysia

As solar energy installations, utility-scale photovoltaic (PV) farms, and high-voltage commercial battery energy storage systems (BESS) expand rapidly across Malaysia, solar engineers and EPC contractors require specialized instruments designed to safely handle ultra-high DC and AC voltages. MTM Precision is proud to present the flagship MESTEK CM86C Photovoltaic Digital Clamp Meter—a purpose-built, high-capacity measurement solution engineered specifically for modern high-voltage solar infrastructure.

Capable of measuring up to 2500V Photovoltaic DC Voltage, 1500V Photovoltaic AC Voltage, and 2500 KVA Power capacity, the MESTEK CM86C far exceeds the limits of standard industrial clamp meters. Certified to EN61010-2-032safety compliance under CAT III 1000V protection, it combines 1000A AC/DC clamp testing (expandable to 3000A AC via an optional iFlex coil), True-RMS signal analysis, VFD variable frequency filtering, 1000A motor/inverter Inrush current capture, and thermocouple temperature diagnostics in a rugged 42mm jaw enclosure.

🌟 Key Features & Solar PV Specialized Capabilities

Ultra-High Solar PV Voltage Ratings: Engineered for modern utility-scale solar arrays with direct measurement capability up to 2500V DC (Photovoltaic DC Voltage) and 1500V AC (Photovoltaic AC Voltage), allowing safe commissioning and troubleshooting of high-voltage PV string combiners and central inverters.
High Power Calculation Capacity: Supports apparent power estimations up to 2500 KVA, enabling field engineers to audit system-level solar inverter outputs and transformer performance.
1000A AC/DC Measurement & Optional 3000A iFlex Coil: Measure up to 1000A AC/DC directly using the 42mm solid clamp jaw. Expand current testing up to 3000A AC using an optional iFlex flexible current clamparound large busbars or dense solar cabling.
1000A Inrush Current Capture: Accurately measures high transient startup surge currents when solar grid-tie transformers, central inverters, or motor-driven solar tracking arrays power on.
VFD (Variable Frequency Drive) Mode: Filters out high-frequency pulse-width modulation (PWM) noise and harmonic interference, delivering clean, true voltage and current readings on inverter-driven equipment and solar trackers.
Large 42mm Jaw Opening & Heavy-Duty Build: Generous jaw capacity readily clamps around thick DC main cables, heavy AC output lines, and solar combiner busbars.
K-Type Thermocouple Temperature Testing: Integrated temperature channel supporting -20°C to 1000°C (-4°F to 1832°F) for rapid thermal checking of solar fuse block connections, DC disconnect switches, and inverter heat sinks.
