Portable Resistive Load Bank
Product Code : LSK-EPS-10535
Portable Resistive Load Bank (SKU LSK-EPS-10535) is a robust steel enclosure holding three banks of switchable resistors, so students can build balanced or unbalanced resistive loads for single-phase and three-phase experiments. Electrical engineering colleges, polytechnics and technical institutes use it on machines and power systems benches. Science Lab Supplies supplies the unit from its base in Ambala, India to institutions, tender contractors and distributors.
Specifications
Each of the three electrically separate banks has its own switches to bring individual resistors into circuit and its own thermally operated circuit-breaker. Loads connect to experiment circuits through safety sockets on the front panel, and the ventilated enclosure has carrying handles.

Applications and Experiments for the Portable Resistive Load Bank
Students switch resistors in and out to set a known resistive load, then measure how a source or transformer behaves as the load changes. Setting the three banks differently creates an unbalanced three-phase load, a condition that is hard to show safely without a purpose-built unit.
- B.E./B.Tech electrical machines: load tests on transformers and generators.
- Star and delta load connection with line and phase measurements.
- Unbalanced three-phase loading and neutral current studies.
- Diploma and technical training: resistive loads for power and energy measurement.
The resistors carry mains-level power and warm up in use; wire with the supply off, keep the vents clear and supervise tests.
Standard Scope of Supply
The load bank arrives as one portable steel unit with its three resistor banks, switches, circuit-breakers and front-panel safety sockets fitted. Connecting leads, meters and the supply are not part of the listing, so they appear as separate lines on the quotation if you need them.
Packing, MOQ and Lead Time
Price one load bank or enough for every bench in the laboratory. The quotation you receive gives packing, delivery time and price for that quantity, and a power factor load bank or other engineering lab equipment in India can be quoted with it for a complete loads section.
Science Lab Supplies, a registered exporter with an Importer-Exporter Code, is able to ship to buyers in Peru, Egypt, Iraq, Nigeria, Kenya and Ghana. Post your enquiry through the contact page, collect items in the enquiry cart, or check the lab tender page for tender purchases.
Frequently Asked Questions
Can it be combined with reactive loads?
Yes. It is designed to work alongside similar capacitive and inductive load banks, giving variable power and power factor loads. Ask about these when you enquire.
How is the load protected against overheating?
Each bank of resistors has a thermally operated circuit-breaker, and the enclosure is ventilated to let heat escape during tests.
Who supplies the Portable Resistive Load Bank?
Science Lab Supplies supplies it from Ambala, India to schools of engineering, polytechnics and contractors, and can add it to a wider power systems order.
Is it easy to move?
Yes. The steel enclosure has carrying handles, so it can be taken from bench to bench rather than fixed in one place.
Related Load and Transformer Equipment
A resistive load is most useful with a source to test and other loads to compare. The power factor load bank adds inductive and capacitive banks, the two mobile transformers give sources for load tests, and the distribution trainer applies loads in a feeder context.
- Power Factor Load Bank — free-standing R, L and C banks on wheels.
- Three Phase Mobile Transformer — three-limb, three-phase transformer with tappings.
- Single Phase Mobile Transformer — three single-phase units with tertiary windings.
- Distribution Trainer — radial and ring main feeder circuits.
