AUTENS

AUTENS AC Digital Meter 80-260V 100A measurement tool

SKU CH-4TME-QYZMS

Measures voltage, current, active power, energy, frequency and power factor on single-phase AC circuits from 80 to 260 volts with a split-core CT up to 100 amps

  • Measures voltage, current, power, energy, frequency and power factor in one panel meter
  • Overload alarm flashes backlight and power reading when active power exceeds your preset threshold
  • Stores the last reading automatically when power is lost so data is not lost
  • Large 51 x 30 mm LCD shows six parameters simultaneously for quick monitoring
  • Split-core CT enables 0-100 A measurement without breaking the conductor

Single-phase AC meter with split-core CT

The AUTENS AC digital meter measures voltage, current, active power, energy, frequency and power factor on single-phase circuits. It operates from 80 to 260 VAC and handles up to 100 A or 22000 W. A split-core current transformer clamps around one hot conductor without breaking the circuit. The large LCD shows six parameters simultaneously.

Panel-mount install; pure sine wave only

The meter fits a standard cut-out measuring 90 by 49.6 mm and sits 25 mm deep. Wiring uses the supplied CT on the live wire and direct voltage taps on the same phase. Backlight and preset overload alarm are configured with the front button. The device only works with pure sine wave sources; modified or square-wave inverters can damage it.

Electricians and energy auditors.

Suited for technicians monitoring mains-fed loads such as panels, heaters or motor circuits where a single hot and neutral are present. The 1 % accuracy class supports cost-allocation and overload protection. Builders measuring three-phase supplies, DC circuits or inverter outputs without confirmed pure sine wave output should choose a different instrument.

Questions about this item

How can I confirm the meter is measuring correctly once installed?

The LCD will display voltage between 80 and 260 VAC, current up to 100 A, active power up to 22000 W, energy up to 999 kWh, frequency between 45 and 65 Hz and power factor from 0 to 1 PF all at once; if the backlight and power reading flash together, the overload alarm has triggered.

What comes in the box and what must I supply?

The package includes the meter and a split-core current transformer; you must provide the single-phase AC supply (one hot and one neutral) within 80–260 VAC and ensure the waveform is pure sine wave.

Which capacity should I select for a load near the meter’s limit?

The meter is rated for 100 A and 22000 W, so choose it only when your circuit stays at or below those values; higher loads need a different instrument.
