Tech OVN white-label OEM DIN rail energy meter range

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 globally — including the Middle East, Southeast Asia, Africa, Europe and Latin America. 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 9-12 months of metrology R&D and type-approval testing.

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 revenue-grade smart meters for the Indian utility market. Most Indian white-label energy meters either rebadge generic Chinese hardware or assemble around a third-party module that's accurate on day one and drifts 2-3% by year five in field conditions. Ours holds inside its accuracy band across the deployment lifetime — the difference between a branded meter range you can stand behind in tenant audits and billing disputes for a decade, and one that becomes a complaint in year four.

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 8-12 weeks. MOQ 5000.

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 5000 Units

Minimum order quantity for white-label and OEM programmes. Catalogue Titan meters have no MOQ and ship single units from stock for pilots and evaluation.

8-12 Week Lead Time

Production ships in 8-12 weeks from confirmed PO depending on customisation scope. Repeat orders against the same SKU ship faster.

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.

Standards-Compliant Out of the Box

IEC 62053-22 (Class 0.5S), IEC 62052-11 and IS 13779 (single-phase static). Skip 6-9 months of certification work.

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

8-12 week production cycle from confirmed PO. End-to-end QC and accuracy calibration at our Delhi NCR facility before dispatch.

5. Repeat Orders & Support

Reorders against the same SKU ship faster. 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

AC and DC EV charger OEMs needing a revenue-grade, type-approved metering board embedded inside the charger — Class 0.5S accuracy without sourcing two vendors.

Solar EPCs & Net-Metering Resellers

Solar EPCs and C&I net-metering resellers bundling a branded export / import DIN rail meter with rooftop installs — bidirectional and MID-track options available.

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 selling into the Middle East, Africa, Southeast Asia, Latin America and Europe under their own brand or a regional sub-brand.

Global Deployment from Delhi NCR

We ship branded DIN rail meters from our Delhi NCR facility to distributors, EMS platforms and brand owners across four continents. Country-specific certifications and protocol variants are arranged as part of the ODM engagement, so the meter you launch in each market is the meter buyers there expect.

Active export-market certifications under qualification: CE marking (Europe), UL listing (USA), UAE ECAS (Middle East). Country-specific bodies including KEMA and MID-track assessment are arranged on the ODM engagement timeline. 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 own DIN rail product line: dedicated metrology IC, calibrated CT inputs, multi-tariff TOD engine, 15-minute load survey, event logging, WiFi / Ethernet / RS485 connectivity and Modbus / MQTT 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 need harmonics, voltage sag/swell and IEEE 519 monitoring alongside the basic meter, the Titan PQ variant ships on the same metrology core with an added power-quality engine.

We ship DIN rail meters from our Delhi NCR facility across the Middle East, Southeast Asia, Africa, Europe and Latin America. Active market focus today: United Arab Emirates, Saudi Arabia, Qatar, Germany, France, Spain, United Kingdom and United States. Country-specific certifications (MID, KEMA, UL, UAE ECAS) and protocol variants are arranged as part of the ODM engagement so the meter you launch in each market is the meter buyers there expect.
The Class 0.5S metering board inside every Tech OVN DIN rail meter is designed in-house by the same engineering team that builds Tech OVN's revenue-grade smart meters for the Indian utility market. Most Indian white-label energy meters either resell rebadged Chinese hardware or assemble around a generic third-party metering module that drifts in field conditions. Tech OVN owns the metrology, the firmware and the enclosure manufacturing — so white-label, OEM and ODM customers deal with a single partner instead of stitching together a board vendor, an enclosure shop and a certification consultant. Commercial terms are also distinct: MOQ 5000, 8-12 weeks from PO, NDA-friendly, no markup on third-party modules.
