White-Label DIN Rail Energy Meters — OEM & ODM Manufacturer in India
Launch your own branded DIN rail energy meter range without designing metrology from scratch. Class 0.5S accuracy, Modbus / MQTT / BACnet, white-label from 1000 units at 4 weeks from PO — built on the CE-marked Titan series, designed to IEC 62053-22.
One Metering Partner. Three Ways to Engage.
Tech OVN is a DIN rail energy meter manufacturer and OEM / ODM partner supplying branded metering hardware to EMS platforms, sub-metering brands, EV charger OEMs, solar EPCs, panel builders and distributors in India and for export. We run metrology, firmware, enclosure manufacturing and protocol stacks in-house at our Delhi NCR facility, so white-label, OEM and ODM customers deal with a single hardware partner instead of stitching together a board vendor, an enclosure shop and a certification consultant.
Whether you're an EMS SaaS launching branded hardware, a sub-metering brand scaling a tenant-billing portfolio, an EV charger OEM that needs revenue-grade metering inside the unit, a solar EPC bundling an export-import DIN rail meter, a panel builder shipping branded metering inside LT panels, or an exporter launching a regional sub-brand — pick the engagement model that fits, and ship branded meters without building your own metrology from scratch.
Why the metering core matters
The Class 0.5S metering board inside every Tech OVN DIN rail meter is designed by our in-house metrology team — the same engineers who build Tech OVN's utility smart meters for the Indian market. Because we own the metrology, firmware and enclosure, your branded range is backed by one partner who can answer for accuracy, register maps and field support — rather than a reseller relaying questions to a module vendor.
White-Label vs OEM vs ODM
Three engagement models — pick the one that matches how much you want to design vs how fast you want to ship.
White-Label
Our reference SKU, your branding. Fastest path to market — pick a model from our DIN rail meter range, send your logo and faceplate spec, ship in 4 weeks. MOQ 1000 units.
OEM
Our DIN rail metering hardware, integrated into your panel, sub-metering product, EV charger or BMS gateway. Board-level or module-level supply available with NDA.
ODM
We design and manufacture to your specification — custom DIN rail enclosure, custom protocol mix (Modbus / MQTT / proprietary), custom firmware. Engineering partnership with NDA from day one.
The White-Label Energy Meter Programme
Everything you get when you engage Tech OVN as your white-label or OEM DIN rail energy meter manufacturing partner.
Your Brand, Your Faceplate
Faceplate logo, packaging, cloud-app branding and Modbus device ID — every customer-facing touchpoint carries your brand, not ours.
Custom DIN Rail Enclosures
Standard DIN rail enclosures ship from stock. We also produce custom DIN rail enclosures to your industrial-design or material spec for differentiated SKUs.
MOQ 1000 Units
A white-label run — your logo, faceplate and packaging on a catalogue SKU — starts at 1000 units. The full OEM / ODM programme (custom enclosure, bespoke Modbus register map or custom firmware) also starts at 1000 units. Catalogue Titan meters have no MOQ: single units ship from stock for pilots and evaluation.
4-Week Lead Time
White-label runs ship 4 weeks from confirmed PO. Custom enclosure, bespoke register map or custom firmware (ODM) adds engineering and pilot-batch time on the first run, agreed at quotation; repeat orders against the same SKU ship in the standard 4 weeks.
Class 0.5S Metering Core
The same Class 0.5S, IEC 62053-22 metering board that powers Tech OVN's own DIN rail deployments — designed in-house, not a third-party module.
CE-Marked Titan Platform
Built on the CE-marked Titan series, designed to IEC 62053-22 (Class 0.5S) and IEC 62052-11. Your launch starts from a finished, documented product rather than a blank metrology project.
Customisation Matrix

Building energy software? Start here.
If you have built an energy product — a monitoring dashboard, an analytics platform, an ESCO service — and need metering hardware behind it, the integration is usually the risk. Most metering vendors want your data in their cloud, and want you to reach it through their platform.
Titan runs standalone. Modbus RTU and Modbus TCP need no internet connection at all. MQTT publishes to your broker. HTTP/HTTPS and TCP/IP push post to your endpoint. The complete register map, command reference and payload examples are published, so your engineers can build and test the integration before you commit to a purchase order.
Evaluate on catalogue Titan meters — no MOQ, single units from stock. Move to a white-label or OEM programme at 1000 units once your product is proven in the field.
From RFQ to Production in 5 Steps
A predictable, NDA-friendly process designed for brands that need to plan launches and inventory in advance.
1. RFQ & Discovery
Share your volumes, target market, branding, accuracy class and protocol needs, plus any custom enclosure or firmware requirements. NDA on request.
2. Quote & Sample
We confirm SKU, customisation scope, and per-unit pricing. Sample units shipped for evaluation against your application and existing systems.
3. Firmware & Pilot Batch
For custom protocol behaviour or enclosure work, we run firmware iteration and a pilot batch. White-label SKUs skip this step and go straight to production.
4. Production
4-week production cycle from confirmed PO for white-label runs; where a custom enclosure, register map or firmware is involved, first-run timing is agreed at quotation. End-to-end QC and accuracy calibration at our Delhi NCR facility before dispatch.
5. Repeat Orders & Support
Reorders against the same SKU ship in the standard 4 weeks. Firmware updates, protocol patches and field-support escalation included.
Who White-Labels with Tech OVN
The buyers we typically engage with on white-label, OEM and ODM DIN rail metering programmes.
EMS & IoT Platform Companies
Energy-management SaaS and IoT platforms that need branded DIN rail hardware to ship under their own SKU — instead of asking customers to source meters separately and integrate after the fact.
Sub-Metering & Tenant Billing
Sub-metering brands serving malls, hotels, IT parks and commercial real estate — branded DIN rail meters for tenant billing, with the metrology and Modbus stack already done.
EV Charger Manufacturers
EV charger OEMs needing a metering board embedded inside the charger — Class 0.5S metering core without sourcing two vendors.
Solar EPCs & Net-Metering Resellers
Solar EPCs and C&I net-metering resellers bundling a branded bidirectional (import / export) DIN rail monitoring meter with rooftop installs, alongside the DISCOM net meter.
Panel Builders & MEP Contractors
Switchgear panel builders and MEP contractors that ship branded DIN rail metering inside their LT panels, ATS panels and energy-monitoring builds.
Exporters & Distributors
Importers and distributors who want to sell metering under their own brand or a regional sub-brand.
Export Markets from Delhi NCR
We sell and ship branded DIN rail meters from our Delhi NCR facility to distributors, EMS platforms and brand owners. Our exports so far have been to Spain; the market pages below cover what we offer buyers in each region.
The Titan series is CE marked. Any further country-specific approval is scoped with you as a separate project. Need a market we haven't listed? Talk to our export team about sub-brand launches and country-specific scope — the distributor and supplier programme covers terms for regional sub-brand operators.
The Metering Hardware Behind Your Brand
Every white-label, OEM and ODM unit ships on the same Class 0.5S metering core that powers Tech OVN's Titan DIN rail product line: dedicated metrology IC, inputs for external Class 0.5S -/5 A CTs, multi-tariff TOD engine, 15-minute load survey, event logging, WiFi / Ethernet / RS485 connectivity and Modbus / MQTT / BACnet protocol support. The metering core is also available as a standalone OEM module for partners that want to build their own enclosure or embed metering into an EV charger, sub-metering gateway or BMS device. For partners that will need harmonics and voltage sag/swell monitoring, the Titan PQ variant (coming soon) is being built on the same metrology core with an added power-quality engine.
