Precision 3.5 kW Resistive Load Bank

Product Code : SCL-EAE-11175

The Precision 3.5 kW Resistive Load Bank is an electrical laboratory load apparatus used to apply controlled resistive loading for current variation, voltage-current study, power-source testing, and electrical machine training. It is suitable for engineering colleges, polytechnics, ITI/TVET centres, electrical laboratories, distributors, and institutional procurement buyers.

Product Description

The Precision 3.5 kW Resistive Load Bank from Lab Equipments Ambala is best positioned under Physics Lab / Electrical and Electronics / Resistance and Current Control Apparatus. A dedicated product page with final product code, resistance range, voltage rating, current rating, phase type, load steps, cooling method, enclosure, protection, and duty cycle should be confirmed before publishing.

A resistive load bank applies electrical load by dissipating electrical energy as heat through resistance elements. In laboratory use, a 3.5 kW resistive load bank can support controlled testing of power supplies, generators, alternators, electrical machine trainers, and circuit panels when operated within the confirmed voltage, current, thermal, and duty ratings.

Key Features

• 3.5 kW load rating: product name indicates 3.5 kW resistive loading capacity; final continuous or intermittent duty rating should be confirmed.
• Controlled resistive loading: supports current variation and practical load-response testing.
• Precision training use: suitable for repeatable electrical measurements when the final resistance steps are confirmed.
• Electrical machine application: useful for loading generators, alternators, power sources, and training panels where the confirmed rating permits.
• Measurement-compatible setup: can be paired with voltmeters, ammeters, wattmeters, multimeters, and power analyzers.
• Resistance apparatus category fit: aligns with rheostats, resistance boxes, meter bridges, and current-electricity laboratory equipment.
• Specifications pending: resistance range, voltage, current, phase, cooling, protection, enclosure, and duty cycle must be verified.

How to Use the Precision 3.5 kW Resistive Load Bank

1. Place the resistive load bank on a dry, stable, ventilated surface with clear space around heat outlets.
2. Confirm the voltage rating, current rating, phase type, 3.5 kW load rating, resistance steps, duty cycle, and earthing requirement before connection.
3. Connect the unit to the power source, generator, alternator, trainer, or machine under test according to the approved wiring diagram.
4. Connect suitable instruments such as a voltmeter, ammeter, wattmeter, multimeter, or power analyzer.
5. Set the load control to the minimum or safest starting position before energising the circuit.
6. Switch on the supply and increase the resistive load gradually using approved switches, taps, or controls.
7. Record voltage, current, power, load step, resistance setting, temperature rise, regulation, or efficiency observations.
8. Reduce the load, switch off the supply, isolate the circuit, and allow the unit to cool before handling or storage.

Safety note: Use the Precision 3.5 kW Resistive Load Bank only within its confirmed voltage, current, phase, wattage, resistance, and duty-cycle ratings. A 3.5 kW resistive load can generate significant heat; use trained supervision, secure earthing, insulated leads, protective switching, ventilation, and cooldown time.

Care & Maintenance

• Keep resistance elements, terminals, switches, vents, controls, and enclosure surfaces clean and dry.
• Inspect insulation, earthing continuity, terminal tightness, overheating marks, and switch movement before operation.
• Do not exceed the confirmed wattage, voltage, current, phase, resistance-step, or duty-cycle rating.
• Store the load bank in a dry, dust-controlled area away from moisture, corrosive fumes, and mechanical impact.

Frequently Asked Questions

What is a Precision 3.5 kW Resistive Load Bank used for?

A Precision 3.5 kW Resistive Load Bank is used to apply controlled resistive load for power-source testing, current variation, voltage-current-power study, and electrical machine training.

Is the 3.5 kW rating confirmed?

The product name states 3.5 kW. The final voltage rating, current rating, phase type, resistance range, duty cycle, and continuous or intermittent load rating should be confirmed before publishing.

Is this the same as a loading rheostat?

It may perform a related function, but a resistive load bank is usually specified by load capacity and resistance sections. Confirm whether the final product uses rheostat-style sliding control, switched steps, or fixed load sections.

What instruments are normally used with this load bank?

Common supporting instruments include voltmeters, ammeters, wattmeters, multimeters, power analyzers, DC or AC power sources, and the electrical machine or trainer under test.

Can students operate a 3.5 kW resistive load bank independently?

No. A 3.5 kW load bank should be operated only under trained instructor or laboratory technician supervision because it can generate high heat and may involve hazardous electrical currents.

What should be confirmed before ordering?

Confirm product code, resistance range or steps, voltage rating, current rating, phase type, wattage, duty cycle, cooling method, terminal type, protection, dimensions, weight, and documentation.
