PZEM-022 CT 100A AC Digital Display Power Monitor Meter Open CT

6-in-1 Comprehensive Power Diagnostics: Simultaneously measures and displays AC voltage (80V - 260V), current (0 - 100A), active power (0 - 22,000W), energy consumption (0 - 9999kWh), frequency (45 - 65Hz), and power factor (0.00 - 1.00PF).

Split-Core (Open-Type) Current Transformer: Features a clip-on open CT sensor allowing quick, non-destructive installation over existing live wiring without disconnecting cables or interrupting circuit operation.

Large High-Definition LCD Display: Displays all six electrical parameters concurrently on a clear, wide-angle LCD screen with full backlight control for easy monitoring in low-light electrical panels.

Overload Power Alarm & Preset Threshold: Built-in power overload alarm allows setting custom wattage limits; triggers display backlight and power numbers to flash when thresholds are exceeded.

Non-Volatile Energy Data Storage: Automatically saves cumulative energy (kWh) readings during unexpected power outages or routine system shutdowns.

Front Panel One-Touch Control Button: Integrated push-button provides instant control over display backlighting and easy manual reset of cumulative energy usage data.

Housing & Core Hardware: Flame-retardant ABS plastic casing designed for clean flush panel mounting, equipped with a durable split-core open CT clamp.

Electrical Specifications & Ratings:

Voltage Range: 80V - 260V AC (50/60Hz).

Current Range: 0A - 100A AC (via included open split-core CT).

Rated Power Capacity: Up to 22kW (22,000W).

Installation Advice: Clamp the split-core CT over only ONE live load conductor wire. Clamping over both Live and Neutral cables simultaneously will cancel out magnetic fields and result in zero current readings.

Maintenance & Cleaning: Keep LCD face and terminal connections clean and free of ambient bench dust using a soft, dry microfiber cloth. Avoid solvent-based liquid cleaners.

Versatile Retrofit Power Monitor: Position as the ultimate non-intrusive monitoring solution for existing electrical panels, sub-metering retrofits, solar inverter output tracking, and generator monitoring where disconnecting main lines is impractical.

Highlight Open CT Convenience: Emphasize the split-core clamp CT design as a major installation time-saver over closed CT meters, avoiding system downtime during setup.
