India's Power Electronics R&D House
We engineer mission-critical power conversion and control systems — 50 KVA modular UPS, railway locomotive VCUs, precision SMPS, and EV chargers — from concept to production.
About Us
Power Electronics, Concept to Production
Joule Labs is a power electronics design and R&D house based in Delhi. We engineer high-voltage products — modular UPS systems, vehicle control units for railway locomotives, switched-mode power supplies, and EV chargers — handling everything from topology selection and magnetics to control firmware and compliance.
To be India's most trusted power electronics R&D company — the engineering partner the nation turns to as it electrifies rail, road, and industry.
To meet India's growing demand for power electronics with world-class, indigenous engineering — taking mission-critical systems from first concept to production reality, without compromise.
Our Process
From Concept to Production
A disciplined R&D approach that takes high-voltage products from specification to production-ready reality.
Specify & Architect
We translate requirements into a rigorous specification — standards mapping, topology selection, and system simulation before a single board is designed.
Design & Prototype
Schematics, magnetics, PCB layout, and control firmware come together in-house, with rapid lab bring-up and iteration on real hardware.
Validate & Deliver
Thermal, EMI/EMC, and endurance testing harden the design, followed by compliance support and a clean handover to production.
Hardware
What We Build
Software
Software Products
Monitoring, control, and safety software for energy, water, and rail — built by the same team that designs the hardware it runs on.
NILM
Appliance-level energy intelligence from a single metering point.
CCMS
City-scale streetlight control, metering, and fault management.
ILM
Per-luminaire monitoring and control, down to the last light.
Energy Meter Management Software
Head-end acquisition, analytics, and billing for smart meter fleets.
PAS
Clear, reliable announcements for metro and railway operations.
DIU
The driver's window into the train — status, faults, and diagnostics.
Water Meter Management
From meter reads to leak alerts — water accounting that adds up.
FogPASS
Landmark alerts for loco pilots when visibility fails.
Why Choose Us
The Joule Labs Difference
Deep power electronics expertise, disciplined engineering, and a commitment to building world-class products in India.
High-Voltage Expertise
From mains input to traction-grade systems, we engineer power conversion that stays reliable at high voltage and high power.
Standards-Driven Design
Designs aligned with EN 50155, IEC 62040, and IEC 61851 from day one, so certification is a milestone, not a surprise.
Hardware + Firmware In-House
Topology, magnetics, PCB layout, and real-time control firmware under one roof — no hand-offs, no gaps.
Built for Production
Every design is engineered with manufacturing, testing, and long-term serviceability in mind.
