Let’s Solve Your DC Shunt Requirements — Together
Work directly with an experienced DC shunt specialist who understands both engineering requirements and procurement realities.
From custom DC shunt specifications to urgent samples and production schedules, we support engineers and procurement teams with clear answers, fast response, and practical solutions.
Whether you are selecting a standard model, adapting a shunt for a specific application, or validating performance for your system, you’ll be speaking with real people who know DC current measurement — not a generic sales desk.
Manufacturing You Can Rely On
From prototyping to mass production, every DC shunt is manufactured in-house under controlled ISO processes — ensuring consistent quality, stable lead times, and full traceability.
Critical steps such as resistance welding, manganin element assembly, calibration, and final inspection are all completed internally. This allows us to maintain tight tolerances, reliable performance, and repeatable results across batches.
For engineering teams, this means predictable electrical characteristics.
For procurement teams, it means dependable delivery and fewer surprises — even during peak production periods.

What Buyers Ask Before Ordering
Absolutely.
We specialize in custom DC current shunts, supporting adjustments in:
Rated current & voltage drop (40mV / 50mV / 60mV / 75mV / 100mV)
Accuracy class (down to 0.1%)
Terminal type, size, hole position, and mounting layout
Material selection (manganin, copper alloys, brass)
Labeling, marking, and packaging requirements
You can send us a drawing, datasheet, or even a reference sample.
Our engineers will either match it directly or suggest a technically safer alternative.
Yes — and this is where most long-term projects start.
We regularly work directly with R&D, electrical engineers, and system designers during:
New product development
Prototype validation
Performance optimization under thermal or overload conditions
Our team provides drawing confirmation, tolerance review, and application advice, so issues are solved before mass production, not after.
Quality control is fully in-house.
Every DC shunt goes through:
Incoming material inspection
Resistance & voltage drop verification
Thermal rise and overload performance checks
Final inspection before shipment
We follow ISO-based production processes, and test reports can be provided upon request — especially for EV, energy storage, and industrial power applications.
Samples: usually 3–5 working days
Small batch orders: 7–15 days
Mass production: confirmed based on quantity and customization level
For urgent projects, we can prioritize production — just let us know your deadline in advance.
We don’t disappear after shipment.
If there’s any issue related to spec mismatch, performance deviation, or damage, we will:
Analyze the root cause with our engineers
Propose a corrective solution
Replace or remake parts when responsibility is on our side
You’ll always have a real person handling the case, not an automated reply.
Yes.
We support low MOQ and trial orders, even from 1 piece, especially for:
Prototyping
Testing new designs
Supplier qualification
Many of our long-term customers started with a small trial before scaling up.
We ship worldwide using DHL, FedEx, UPS, or customer-appointed forwarders.
Export packaging is standard, and all shipments include:
Commercial invoice
Packing list
Compliance documents if required (RoHS / REACH / Prop 65)
We regularly ship to USA, Europe, India, Japan, Korea, and the Middle East.
Our DC shunts are widely used in:
EV & BMS systems
Energy storage & inverters
Welding machines
UPS & industrial power supplies
Test & calibration equipment
If you share your system type or measurement method, we’ll confirm compatibility or recommend the most suitable model.
Most clients come to us for one of three reasons:
Faster response & clearer communication
Better support for customization
More stable quality across batches
We may not always be the cheapest — but we focus on being reliable, responsive, and technically accountable.
