PZEM-014/016 is the module you want for PC only interface, PZEM-022 for display only. **Q: For 240v install/Monitoring, instead of running a hot and neutral (black and white) to the display, can I run both black legs from 240v (120v + 120v)?** A: +1 what brycen says for United States 240V split phase service that uses 2 120V circuits. I clamped the coil over one of the hot legs and wired each hot leg to the load terminals on the meter. All measurements were accurate; amps, watts, volts, hertz, total power used, and power factor. I'm using this meter to monitor power supplied to a heating element for a brew kettle, which utilizes a Blichmann power controller to power the heating element. If you're using this for a similar purpose, wire the meter into the circuit BEFORE the power controller. Initially I wired it after the controller, which resulted in inaccurate readings.. **Q: does this work without having neutral wire? in many (old) houses in Saudi Arabia we use 2 x 110V = 220V, both live** A: yes, I have one in the us on 240volts. 2 hot wires, one to the terminal marked hot and the other hot to the terminal marked neutral and it has been working for over a year so far. **Q: Can this meter be powered by 120v ac and used to read 220v ac for an air conditioning compressor?** A: As suggested, I bought two meters. Each is clamped over one leg of the power for the AC (120v+120v). I see current, volts and amps for each leg. Each meter is plugged into a standard 120v outlet. They are mounted in the garage on the wall opposite the breaker box (which is on the outside of the house.) Now I need a way to capture the information. I have an app that captures how often the AC blower fan comes on. I suppose if I get some averages of amperage used by the rest of the AC unit, under various outside temperatures, I can get a rough idea of how much power is being used. ## Frequently Bought Together - AC Current Voltage Amperage Power Energy Panel Meter LCD Digital Display Ammeter Voltmeter Multimeter with Split Core Current Transformer CT AC 80-260V 100A Multi-Function Power Monitor - Otdorpatio Junction Box IP65 Waterproof ABS Plastic Electrical Project Case Power Junction Boxes, Project Box with Fixed Ear Black 7.87 x4.72 x2.95 inch (200x120x75 mm) - AC 80-260V 100A LCD Digital Display Multi-Function Power Monitor Voltage Current Frequency Power Factor Energy Meter Ammeter Voltmeter with Split Core Current Transformer --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/551697147-ac-current-voltage-power-energy-frequency-power-factor-communication-module](https://www.desertcart.co.za/products/551697147-ac-current-voltage-power-energy-frequency-power-factor-communication-module) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-06-18*
