Design and manufacture of HF inverters, DC-DC converters, magnetics, and bespoke power electronics for industrial, defence and rail customers. ISO 9001-aligned production with full traceability.
From the first concept sketch to the heat-run bench, every unit we ship is engineered, built and tested under one roof. Our customers come back because we treat their projects as our own — drawing-controlled BOMs, full material traceability, zero shortcuts on quality.
Schematic + PCB + magnetic design done in-house. Customer drawings honoured to the dimension.
Bobbin winding, varnishing, core prep, SMT, assembly, packaging — all on the floor.
Every component carries a PointeR part number; every cut from every roll logged; every stage signed off.
Heat run + electrical test + dimensional + in-house QI + agency inspection on demand.
Catalogue + custom designs for industrial, rail and defence applications.
Push-pull HF topology · 24V DC input · isolated AC output · 95% efficiency at full load · field-proven in rolling stock.
Wide-input DC-DC · regulated output · short-circuit and over-temp protection · DIN-rail or panel-mount.
High-current rail · designed for battery-charging and traction auxiliary loads.
Industrial sensor interface · galvanic isolation · loop-powered options · field-replaceable.
A floor that takes a drawing and delivers a tested unit.
Bobbin winding, wrapping, varnishing, inductance + insulation testing — bespoke transformers and inductors.
SMT + through-hole · bare → assembled → tested PCBs · variant tracking under one drawing reference.
Copper / aluminium / MS sheet cut, formed and finished · offcut tracking for material yield.
Burn-in chamber + electrical bench · parameter logged per unit · pass/fail recorded with the unit's QR.
MOSFET / IGBT power stages with gate drivers and heatsinking.
Input, output and EMI inductors wound to specification.
Door modules, lock-and-fit hardware, cooling fans and panel accessories.
Documented packing list, IRN, e-way bill — ready for any consignee.
ISO 9001-aligned processes, full SOP for purchase and production, every component traceable to its source.
Per-category templates · 13 parameters · quantity / material-cert / test-cert verification per SOP §11.
Standard 6-reason rejection codes (Component / Duplicate / Transit / Spec / Dimension / Documentation) · Return-to-Vendor tracking.
Duration or Pass-Fail or both · temperature / voltage / current readings logged across the run.
BIS · NABL · CPRI · ERTL · customer's own engineer — paper certificate captured against each Work Order.
Long-running partnerships with rail, defence, industrial automation and renewable-energy customers.
Power supplies and converters for rolling-stock electronics — designed to RDSO + customer specs.
Ruggedised supplies + magnetics with full inspection chain and conformance documentation.
Signal converters, regulated supplies and bespoke driver electronics for control panels.
Inverter sub-systems and battery-side electronics for solar and storage applications.
From a one-off prototype to a multi-thousand-unit production run, we'd love to put a proposal together.
