Ideal for diverse environments including industrial, commercial, and residential, it auto-saves data on power loss and supports easy resets for multiple measurement cycles. ## Description KETOTEK Single Phase Energy Meter, DIN Rail Power Meter KWH Meter AC 80-300V 100A, Kilowatt Hour Volt Amp Watt CT Sensor: desertcart.com: Industrial & Scientific ## Features - 【One-click data switching】This KWH meter is able to display measured AC voltage, current, power factor, active power, electric energy and accumulation time. The red and green LED can help you get the digital easy. When pressing the SAM CK button, the electric meter will change to display the measurement result of power factor (cosφ), cumulative time (h) and the electricity (kwh), the correlative red LED will light up. - 【Technical indicators】Voltage: AC 80-300V, Current: AC 0.0-100A, Active power: 0.0-30000W, Electric energy: 0-99999kwh, Power factor: 1.000-0.000, Electric energy of cumulative time: 0.00-999.59h. - 【Safe and high precision】This single phase energy meter features high quality ABS flame resistant material and percision chip, making it safe to use. Accuracy is 1％±2 digits, measuring Speed is 2 times/s. - 【Data storage & reset】1.Data reset for multiple measurement needs. When the watt meter displays electrical energy, press the SAM CK button for five seconds, the meter will be reseted. 2.The value of electric energy and electric energy of cumulative time will be automatically saved when power off, and when the measurement power is reconnected,the meter will go on cumulating data. - 【Multi-field application】This ac power meter din rail is built in transformer which can meet the load maximum current 100A. It can be used in school, market, home, industry, laboratory and other fields. Attention: This energy meter can only use to measure 50/60HZ AC city electricity. It will be destroyed when used to measure square waves, output of inverter, or non-standard sine waves. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01ANVFCG2 | | Brand Name | KETOTEK | | Color | Green, Red | | Customer Reviews | 4.6 4.6 out of 5 stars (50) | | Item Dimensions | 3.15 x 2.13 x 2.52 inches | | Item Weight | 0.13 Grams | | Manufacturer | KETOTEK | | Measurement Type | Multimeter | | Part Number | D52-2047 | | Power Source | Corded Electric | | Specification Met | CE | | Style Name | AC 80-300V | | UPC | 723260100005 | ## Product Details - **Brand:** KETOTEK - **Color:** Green, Red - **Item Weight:** 0.13 Grams - **Power Source:** Corded Electric - **Style:** AC 80-300V ## Images ![KETOTEK Single Phase Energy Meter, DIN Rail Power Meter KWH Meter AC 80-300V 100A, Kilowatt Hour Volt Amp Watt CT Sensor - Image 1](https://m.media-amazon.com/images/I/71foZTc9YJL.jpg) ![KETOTEK Single Phase Energy Meter, DIN Rail Power Meter KWH Meter AC 80-300V 100A, Kilowatt Hour Volt Amp Watt CT Sensor - Image 2](https://m.media-amazon.com/images/I/51rcWmJmjaL.jpg) ![KETOTEK Single Phase Energy Meter, DIN Rail Power Meter KWH Meter AC 80-300V 100A, Kilowatt Hour Volt Amp Watt CT Sensor - Image 3](https://m.media-amazon.com/images/I/51yAdWr-U5L.jpg) ![KETOTEK Single Phase Energy Meter, DIN Rail Power Meter KWH Meter AC 80-300V 100A, Kilowatt Hour Volt Amp Watt CT Sensor - Image 4](https://m.media-amazon.com/images/I/61vfatgX+4L.jpg) ![KETOTEK Single Phase Energy Meter, DIN Rail Power Meter KWH Meter AC 80-300V 100A, Kilowatt Hour Volt Amp Watt CT Sensor - Image 5](https://m.media-amazon.com/images/I/51DDJF2ZcsL.jpg) ## Questions & Answers **Q: Am planning to use an external ct. what ct ratio should i use? any recommendations?** A: hi, The CT is designed to built inside the product. you can't use external ct. As you can see in the picture, there is a hole in the meter. The CT is built around the hole inside the meter. The wire go through the hole is equal to go through the CT. **Q: Can the KWH be reset?** A: yes， it can be reset. When powered off, the meter can save the value of electric energy and electric energy of cumulative time, and go on cumulating data when the meter is powered on again. When the meter is displaying electric energy, you can press down SAM CK button to reset the electric energy and electric energy of cumulative time to zero. **Q: Can i use this to monitor voltage, amperage from a conventional residential electrical panel to a standard 3-prong outlet?: 120v 50 amp breaker 60hz?** A: Yes as long a it's single phase. The unit has two small screw terminals for power to the unit and voltage sampling. And a 3/8" hole through it top to bottom with an inductive ampmeter coil. You just pass your hot wire through the hole and it samples the amperage. It will easily fit a #6 wire. **Q: What would be the connections for a US 240 V without neutral?** A: You still have to run a neutral to it or a ground. --- ## 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.gr/products/25853621-ketotek-single-phase-energy-meter-din-rail-power-meter-kwh](https://www.desertcart.gr/products/25853621-ketotek-single-phase-energy-meter-din-rail-power-meter-kwh) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-06-18*
