Typical Applications:Residential energy monitoringSmall business power trackingElectrical sub-meteringLoad management systems Compliance Information: This DIN-rail Kilowatt Hour kwh Meter is designed for AC circuits only.It is recommended that the kilowatt meter be installed in the electric meter box.For optimal performance and safety, we recommend installation by a qualified electrician professional installation. Review: This is a reasonably priced and accurate meter - good for electric car charging outlets - I was hesitant to buy this at first because the picture showed a 50 Hz model and I wasn't sure from the markings whether it would handle 20 amps or 100 amps - I wanted something for 50 amps of 240 volts for charging my Tesla. After a few questions and getting prompt answers from the vendor, I felt assured and purchased it. Connections are pretty straight forward, but you are dealing with very high power and voltage so it is better left to an electrician if you are unsure. This needs to be mounted inside a box so that connections are all protected. I fit it in a standard Jbox, just barely, with a customized cover plate, but I saw some ready made boxes are available and those seem like a good choice. This has been working well for me for several months. A little red dot flashes to indicate energy being delivered. This cross checks well to the Tesla's built-in measurement of kWh and provides a nice running total to help you make decisions such as what electrical rate plan to choose. It also can help you see the "phantom power" used by leaving the car plugged in after a full charge. Review: it works and easy to install , does not reset - I installed 1 on my Dryer and 1 on my Central AC , i am righting down the usage numbers each month so i know what these appliances are using just by themselves , do not cut your wires to install this, be sure all covers are on before turning power back on, I have duel single phase electric, I installed mine beside my main electric panel, do not try this on your own if you do not know how electric works and you if you have not worked with electric before, you can NOT reset the numbers after reading ,same as your main electric meter, ## Features - Accurate Single-Phase Energy Meter – Class 1.0 accuracy kWh meter designed for precise power consumption measurement in 220V split-phase systems, Ideal for residential and light commercial use - Wide Compatibility & High Capacity – Supports 20(100)A current range (max 100A) and operates at 60Hz ±10%.

My apartment has a separate feed to the water heater, bypassing the indoor fuse-box where I have a whole-house energy monitor. So to get total energy consumed, I add this reading to the other monitor and both combined usually match the KwH meter on side of building. But it's much easier to just check my indoor meters rather than trek outside. ## Frequently Bought Together - Baomain Single Phase Energy Meter 2 Wire 220V DIN-Rail Type Kilowatt Hour kwh Meter 60Hz 20 (100) A - LMioEtool ABS Plastic Dustproof Waterproof IP65 Junction Box Hinged Shell Universal Electrical Project Enclosure Gray, with PC Transparent Clear Cover 8.7 x 6.7 x 4.3inch(220 x170 x110mm) - 1 Piece DIN Rail Slotted Aluminum RoHS 12" Inches Long 35mm Wide 7.5mm High --- ## 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.us/products/16259687-baomain-dds238-4-din-rail-single-phase-kilowatt-hour-kwh](https://www.desertcart.us/products/16259687-baomain-dds238-4-din-rail-single-phase-kilowatt-hour-kwh) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-21*
