Smart Energy Meter Manufacturer for Wholesale and OEM Supply

Jiangsu Saving Electronics Co., Ltd. is a smart energy meter manufacturer based in China. We build single phase and three phase meters, power data gateways, and cloud-based energy management software. Moreover, we supply utilities, distributors, contractors, and brand owners around the world. Our factory runs the full chain, from hardware design and molding to final testing and shipping. As a result, buyers can order in bulk, add their own brand, and get technical help from one team. This page explains who we are, what we make, and how we work with business partners.

Who We Are: A Factory, Not a Trading Company

Saving Meter is a one-stop energy metering and management service provider. Our core is the smart electricity meter, yet our work goes far beyond that. In addition, we design data terminals, build cloud software, and manage system integration and daily operation.

Because we own the production line, we control cost, quality, and lead time. Therefore, you talk to engineers and planners instead of middlemen. We also hold long-term supply deals for key parts, which keeps output steady even when the market is tight.

What We Make: A Full Range of Metering Products

Our product line covers most business metering needs. For example:

• Single phase smart meters — the G-type DDZY1218-Z, DDSU1218, and DDZY1218-GJ models for homes, shops, and small sites.

• Three phase meters — DTS1218, DTSU1218, and DT/SZY1218-D units for plants, malls, and large buildings.

• Fee-control and prepaid meters — built-in load control and prepayment for landlords, campuses, and industrial parks.

• DIN rail meters — compact units that fit standard panels and save cabinet space.

• Power data gateway terminal — the RTU1218 with 4G uplink and LoRa downlink for wireless reading.

• Cloud platform and software — remote reading, alarms, reports, and energy analysis.

Each meter works with RS485, Modbus, DL/T 645, 4G, or LoRa communication. Meanwhile, our meters meet GB/T 17215.321-2021, GB/T 17215.322-2022, and IEC 62053-21/-22 accuracy rules. The International Electrotechnical Commission (IEC) writes these accuracy classes, so a class 1 meter reads and bills with a tight tolerance (IEC).

Built for B2B Buyers: What Business Partners Get

Wholesale buyers need more than a product. They need a supplier who ships on time and answers fast. However, many sellers stop at a low price and leave the rest to you. We take the opposite path, and we build our service around real trade needs:

• Bulk pricing that scales with your order size

• OEM and ODM support for your own brand

• Sample units for testing before mass production

• Firm lead times backed by production planning

• Technical files, drawings, and test reports for bids

• After-sales help, spare parts, and firmware updates

Besides that, our team speaks the language of tenders and projects. So we can join your bid early and help you shape the specs.

OEM and ODM Service: Your Brand, Our Factory

Many partners want to sell under their own name. We support that in two ways.

OEM means we build to your design. You send the specs, and we produce and test them. ODM means you pick from our ready platforms, and we adjust the housing, logo, labels, and packaging.

In both cases, we guard your data and your mold. For instance, custom panels, colors, and nameplates are common requests. As a result, your products reach the market faster, and you avoid the cost of building a new factory.

Quality Control and Certifications

Quality is not a promise on paper. It is a process. Firstly, we source chips and parts from approved suppliers. Secondly, every meter passes function tests, accuracy checks, and aging runs. Finally, we pack and inspect before shipping.

Our meters carry the marks that buyers ask for, such as CE, RoHS, and IEC-based test reports. Likewise, we can arrange third-party inspection at your request.

Manufacturing Capacity and Supply Chain

Our plant uses modern SMT lines and automatic calibration. Therefore, we can hold steady output for repeat orders and ramp up fast for large tenders.

In addition, our supply chain is mature. We keep key parts in stock, and we have backup vendors for critical items. That way, one supplier delay does not stop your order.

Applications and Industries We Serve

Our meters and systems fit many markets:

• Power utilities and grid projects

• Commercial buildings, data centers, and factories

• Solar and storage projects that need bidirectional metering

• Agricultural irrigation and prepaid power sales

• Industrial parks, campuses, and rental housing

• Municipal and pollution control facilities

You can see how these work in our real cases, such as the data center infrastructure monitoring system and the agricultural irrigation power solution.

Let Us Quote Your Project

In short, Saving Meter is a maker, not a reseller. We build meters, write software, and stand behind both. Whether you need a container of DIN rail meters or a whole energy management system, our team can help.

The International Energy Agency (IEA) calls energy efficiency the "first fuel," the cheapest way to meet rising power demand (IEA). Better metering is where that saving starts. So send us your list today, and we will reply with models, prices, and a clear plan.
