Portable Resistive Load Bank
Portable Resistive Load Bank (Product Code: SLE/EPS/10) is a three-phase resistive load used to draw controlled real power from generators, transformers and supply circuits during power systems practicals. Each of its three resistor banks is electrically separate and carries its own thermal circuit-breaker, so students can build balanced or unbalanced star or delta loads. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM, at its own factory in Ambala, India, within its engineering educational equipment in India range.

What Is the Resistive Load Bank Used For?
A resistive load takes current in phase with the voltage, so it absorbs real power at unity power factor and turns it into heat. That makes this unit the reference load in most power practicals: students add load resistor by resistor and record how a source’s terminal voltage, current and output change as demand rises.
Switch the three banks to different settings to create unbalanced conditions, or connect them in star or delta to compare line and phase quantities. When a non-unity power factor is needed, the resistive banks are combined with other similar load banks. Allow pauses between heavy load steps — the resistors run warm, and each bank’s thermal circuit-breaker is there to protect them.
What to Specify When Ordering
- Your supply voltage and the power you expect to dissipate, so suitability can be checked (ratings are not listed on this page).
- Any companion loads you need, such as the inductive or power factor load bank.
- Number of units for your benches.
OEM Manufacturer
Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM (original equipment manufacturer) of the Portable Resistive Load Bank. Rather than reselling a trader’s stock, the company makes and assembles each unit at its own licensed factory at Saha, Ambala, Haryana, India, and supplies it factory-direct to institutions, dealers and importers.
Quotations come straight from the manufacturer, and spare parts can be requested directly — just ask us. Company information is on the ScienceLab profile page.

Frequently Asked Questions
What does the Portable Resistive Load Bank contain?
The Portable Resistive Load Bank (SLE/EPS/10) is a robust steel enclosure with three banks of switchable resistive loads. Each bank has a set of switches to bring each resistor into circuit, and safety sockets on the front panel connect it to experiment circuits.
Can the Portable Resistive Load Bank create unbalanced loads?
Yes. Because each bank of the Portable Resistive Load Bank is electrically separate and switched independently, students can create balanced or unbalanced resistive loads, connected as a star or a delta load for three-phase circuits.
How is the Portable Resistive Load Bank protected?
Each bank of resistors in the Portable Resistive Load Bank includes its own thermally operated circuit-breaker to protect the loads, and all connections to experiment circuits are made through safety sockets on the enclosure front panel.
Can it be used for power factor experiments?
Yes. The Portable Resistive Load Bank can be used with other similar load banks, for example the inductive load bank, to provide variable power and power factor loads. On its own it presents a purely resistive, unity power factor load.
Who manufactures the Portable Resistive Load Bank?
Jain Scientific Equipments Pvt Ltd (ScienceLab) manufactures the Portable Resistive Load Bank as the OEM at its own licensed factory in Saha, Ambala, Haryana, India, and supplies institutions and dealers across India and international markets directly.
What are the resistance values and power rating?
Resistance values and the power rating of the Portable Resistive Load Bank are not published on this page. Tell ScienceLab your supply voltage and required load through the contact page, and we will confirm suitability before quoting.
