Product Code : SCL-EAE-12042
Resistive Load Bank 240V AC (SKU SCL-EAE-12042) is a bench-mounted, switchable real-power load of up to 3 kW for testing generators, inverters and circuits on a 240 V single-phase supply. Electrical engineering students and laboratory technicians use it to study current draw, voltage stability and power under changing load. The unit is manufactured by Science Lab Supplies in its Saha, Ambala works (Plot 448, HSIIDC Industrial Area) and offered directly to colleges, institutes, tender contractors and distributors.
Specifications
All technical details appear in the table below. In short, the bank uses heavy-duty ceramic-sheathed or wire-wound resistors in a ventilated, powder-coated steel case, switched in five steps up to 3 kW at 240 V, with a built-in axial cooling fan and an over-temperature trip.

Applications and Experiments for the Resistive Load Bank
The bank lets students apply known real-power steps to a single-phase source and record how its voltage and current respond. It suits electrical machines and power-systems practicals in diploma, B.Tech and vocational electrical courses, where unity power factor loading is the starting point for regulation and efficiency tests.
- Generator and alternator tests: loading a small educational machine step by step to plot voltage regulation, with readings on an Analog Power Measuring Meter.
- Inverter testing: checking the efficiency and thermal behaviour of single-phase backup or solar inverters.
- Power relations: confirming P = V²/R from supply readings taken with an Analog Panel Voltmeter 500V AC/DC.
It works at mains voltage and its case gets warm: keep the grilles clear and use it only under trained supervision.
Standard Scope of Supply
Each delivery contains the load bank enclosure, a heavy-duty AC mains input cord, four high-current insulated patch cords with 4 mm safety connectors and an English operating manual with sample calculations and experiment setups. Measuring meters and the source under test are separate items that can be quoted alongside.
Packing, MOQ and Lead Time
Ask for a price on one bank for a machines bench or on several for a full power lab. Each quotation from Science Lab Supplies, a science apparatus manufacturer in India, gives the packing, delivery time and price for that quantity, and panel meters can be quoted with the banks.
Science Lab Supplies holds an Importer-Exporter Code and can ship to buyers in Oman, the Philippines, Nepal, Bangladesh, Zambia and Rwanda. Write to us on the contact page, place the items in the enquiry cart, or use the lab tender page for a tender schedule.
Frequently Asked Questions
What is the maximum load of this bank?
It handles up to 3 kW (3000 W) on a 240 V, 50/60 Hz single-phase supply. Five switched steps of 200, 400, 600, 800 and 1000 W can be combined to set intermediate loads.
What happens if the bank overheats?
A thermal overload trip disconnects the resistor elements if the internal temperature passes its safe limit. The axial fan runs from the 240 V input whenever the unit is energised, so keep both grilles unobstructed.
How should the bank be shut down after a test?
Switch the load steps off first and let the cooling fan run for three to five minutes before disconnecting the main input. Avoid touching the metal case until it has cooled.
Is this load bank made by Science Lab Supplies?
It is. Science Lab Supplies, a laboratory equipment manufacturer in India, builds the bank at its own factory in Saha, Ambala, India, and colleges or contractors deal directly with the maker when they request a quotation.
