Manufacturer description

The MORNING GROUP AC 80-260V 100A Digital Power Monitor gives you six live electrical readings from a single 1.1-inch-tall panel: voltage, current, active power, energy, frequency, and power factor, all displayed at once on a large LCD. This 2-pack ships with split-core current transformers, so you clamp each CT around an existing conductor instead of cutting and re-terminating your service wiring — the practical difference between a ten-minute install and an afternoon of rework on a retro bench, breaker subpanel, or vintage AT power supply you want to profile. A configurable overload alarm…

SpecPicks Verdict

SpecPicks scored MORNING GROUP AC 80-260V 100A Digital Power Monitor using a rating × review-volume × price-fit model applied to published specs and reviews across the tools & maintenance category. MORNING GROUP's tools & maintenance lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for tools & maintenance: PC towers accumulate significant dust in 3–6 months, so cleaning frequency drives cordless vs. canned-air tradeoff decisions. Match the device's RPM or CFM rating to your case size, and confirm battery runtime covers a full tower cleaning before ordering. Prices and stock are set by the retailer and may have moved since this page was last updated.

Frequently Asked Questions

Do I have to cut my wiring to install this?

No. It ships with a split-core current transformer that opens and clamps around the existing conductor, so the current path stays intact. The meter still needs an AC connection in the 80-260V range to sense voltage.

What does it actually measure?

Voltage, current, active power, cumulative energy, frequency, and power factor, all shown simultaneously on the LCD rather than cycled through separate screens.

Will I lose my energy total during a power outage?

No. The automatic data storage function writes the last test data to memory when the supply is abruptly lost, so the accumulated reading is preserved.

Can I set a wattage limit and get warned?

Yes. You preset the power limit yourself with the button, and when consumption exceeds it the backlight and power reading flash together as an overload alarm.

Why is my screen dark after wiring it up?

If you have the PZEM-022 version, the display requires an external power supply to illuminate. The blue backlight is also manually switchable on and off, so confirm it has not simply been toggled off.
