They fit on the DIN rail but will require the live conductor lugs cutting off. The units have cable connections in and out. They are rated to 45amps, I’m using them in supplies rated to 40amps. Review: Easy to install - Spot on works as described by seller ## Features - ENERGY MONITORING – Track the energy consumption of your home or office in real time! This advanced energy monitor measures active energy (kWh) of low-load circuits (45 A rated) with a pulse output. - EASY-TO-READ DISPLAY – The non-resettable meter is equipped with a 6-digit LCD display (without backlight), showing values in 4 integrals + 1 decimal place. The maximum reading is 99,999.9 kWh. When the reading exceeds 10,000 kWh, the meter displays 5 integrals + 1 decimal place. - PULSE CONNECTION – Our power meter uses a pulse output isolated from the internal circuit to generate pulses proportional to the measured energy. This requires an external voltage supply of 5–27 V DC with a maximum input current of 27 mA DC. - ENERGY-SAVING POTENTIAL – The meter features an LED light with a constant of 1000 imp/kWh, which flashes when power is consumed. The more power used, the faster it blinks. This makes it easy to monitor your consumption and save valuable kWh. - SUB-METERING – This energy monitoring tool provides a detailed breakdown of the energy consumption of a single circuit. Ideal for monitoring individual circuits and for accurate sub-billing through precise measurement and tracking of energy usage. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08X8SD1FD | | Batteries Required? | No | | Batteries included? | No | | Best Sellers Rank | 33,904 in DIY & Tools ( See Top 100 in DIY & Tools ) 13 in Power Monitors | | Colour | White | | Customer Reviews | 4.5 4.5 out of 5 stars (108) | | Date First Available | 23 Feb. 2021 | | Included Components | no components | | Item Weight | 90 g | | Item model number | SDM120-MODBUS-MID | | Manufacturer | Eastron | | Part Number | SDM120-MODBUS-MID | | Product Dimensions | 10 x 7 x 8 cm; 90 g | | Style | SDM120-MODBUS-MID | ## Images ![SDM120 Modbus - Image 1](https://m.media-amazon.com/images/I/71oRbM+zrFL.jpg) ![SDM120 Modbus - Image 2](https://m.media-amazon.com/images/I/61Z-Bs9dohL.jpg) ![SDM120 Modbus - Image 3](https://m.media-amazon.com/images/I/717tfTPQBfL.jpg) ![SDM120 Modbus - Image 4](https://m.media-amazon.com/images/I/71BNHn-hRJL.jpg) ![SDM120 Modbus - Image 5](https://m.media-amazon.com/images/I/71PLl8tHniL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: Can you use a ct clamp with this** A: This is a direct connected version, we have a CT version available to supply direct.

In my case that's in the consumer unit in an outbuilding that I wanted to know the specific electricity usage for. Fitting was OK, but per the photo I did need to bend the consumer unit's bus bar a little as the screw terminal locations in this meter were staggered relative to the standard MCBs to be fed from it. The screw terminals are of course also eccentric across the meter as there are two side by side in the 1U width meter, and they're also thinner than the bus bar was. Not insurmountable in this case, but perhaps a differing standard somehow. As far as the meter in use, it works perfectly (as far as I can tell for accuracy anyway) and has been very handy. ## Frequently Bought Together - Modbus Single Phase, Electric Energy Meter - Electricity Meter to Measure Low-amp Circuits - Pulse Output 1 1000imp/kWh - RS485 Modbus - SDM120-MODBUS-MID - Teltonika RUT200 4G LTE Mobile Router - WiFi 4, 4G LTE Cat 4 Router with Embedded SIM Slot & External Antennas - Upgrade with Additional Data SIM --- ## 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.ma/products/294802383-sdm120-modbus](https://www.desertcart.ma/products/294802383-sdm120-modbus) --- *Product available on Desertcart Morocco* *Store origin: MA* *Last updated: 2026-06-04*
