In-house Resistor Manufacturing
Load elements are wound, coated and burn-in tested on our own lines, so element tolerance, temperature drift and derating behaviour are controlled rather than sourced.
About Us
Built in the Factory, Proven in the Field
3M Load Bank designs and manufactures resistive test loads for teams who have to prove that a power system holds up under real load — not on paper. We build the load elements, cabinets, cooling packages and control systems ourselves, which is why we can quote a non-standard voltage, an unusual step pattern or a space-constrained cabinet without redesigning around a catalogue.
Our equipment is used for UPS and generator acceptance testing in data centers, shipboard and shore-supply commissioning in shipyards and naval programs, inverter and energy-storage validation on new-energy sites, ground-power and avionics testing in aerospace facilities, and factory acceptance testing at generator manufacturers.
Most projects start as a specification conversation: rated power, voltage and frequency, step resolution, power factor, control protocol, ambient conditions and how the unit has to be moved on site. From there we scope a configuration, confirm cooling and exhaust requirements, and manufacture to that specification.
- Power range
- 1 – 2000 kW
- Container capacity
- up to 6000 kVA
- Voltage range
- 0 – 10.5 kV AC/DC
- Temperature drift
- ≤ 1%
How We Work
Full Power Range, 1kW to 2000kW
Air-cooled, liquid-cooled (3M8000 series), air-liquid hybrid, container-type, rack-mount and portable formats — built to the voltage, frequency and step resolution the test program needs.
Test Before Ship
Every unit is run at rated load before crating: step accuracy, power factor behaviour, exhaust temperature, noise level, control protocol and metering are recorded on a test report that ships with the equipment.
Engineer-to-Engineer Support
Enquiries reach a manufacturing engineer, not a reseller. Single-line diagrams, cable sizing, cooling loop requirements and Modbus integration are scoped directly with your commissioning team.
04 / Factory & Credentials
A Factory Behind
Every Test Report
We design, build and test resistive load banks in-house — so the engineer answering your technical questions is the same team that welds the frames and signs off the test data.
- Certified Manufacturing
- ISO 9001 quality management with CE-conformant electrical design; certificates available on request for tender documentation.
- 100% Factory Testing
- Every unit runs a full-load burn-in and metering verification before dispatch, delivered with its own test report.
- Built to Your Spec
- Custom power ranges, voltages, frequencies, cooling architecture, control protocols and enclosure ratings.
- Export-ready Delivery
- Typical 4–8 week lead time, export-grade crating, and remote commissioning support wherever the units land.
