Variable Resistance Load Bank 12 kW

Product Code : SCL-EAE-11165

The Variable Resistance Load Bank 12 kW is an electrical laboratory load apparatus used to apply controlled resistive loading for power-source testing, electrical machine experiments, current variation, and load-response studies. It is suitable for electrical engineering laboratories, polytechnics, ITI/TVET centres, engineering colleges, training institutes, distributors, and institutional procurement buyers.

Product Description

The Variable Resistance Load Bank 12 kW 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, voltage rating, phase type, resistance steps, current rating, cooling method, terminals, and duty cycle should be confirmed before publishing.

A resistive load bank provides an electrical load by dissipating electrical energy as heat through resistance elements. In laboratory use, a 12 kW variable resistance load bank is typically used to load generators, alternators, motors, power supplies, and electrical-machine trainers under controlled conditions, subject to the confirmed voltage, current, phase, and safety rating.

Key Features

• 12 kW load rating: product name indicates a 12 kW resistive loading capacity; confirm final duty rating before procurement.
• Variable resistance loading: intended for controlled load variation during electrical testing.
• Electrical machine training: suitable for generator, alternator, motor, and power-source experiments when correctly rated.
• Resistive load principle: dissipates electrical energy as heat through resistance elements.
• Measurement-based use: can be paired with voltmeters, ammeters, wattmeters, multimeters, and power analyzers.
• Electrical and Electronics category fit: aligns with resistance, rheostat, and current-control apparatus.
• Specifications pending: voltage, current, phase, resistance steps, cooling, enclosure, and terminal design must be verified.

How to Use the Variable Resistance Load Bank 12 kW

1. Place the load bank on a stable, ventilated surface with clear space around heat outlets.
2. Confirm the voltage, current, phase, load rating, duty cycle, and earthing requirement before connection.
3. Connect the load bank to the power source or machine under test according to the approved wiring diagram.
4. Connect suitable meters such as voltmeter, ammeter, wattmeter, or power analyzer as required.
5. Set the load control to the minimum or safest starting load position.
6. Energise the circuit and increase load gradually in approved steps.
7. Record voltage, current, power, temperature, speed, regulation, or efficiency readings as required.
8. Reduce the load, switch off the supply, and allow the unit to cool before disconnection or storage.

Safety note: Use the Variable Resistance Load Bank 12 kW only within its confirmed voltage, current, power, phase, and duty ratings. A 12 kW load can generate substantial heat; use proper earthing, ventilation, trained supervision, insulated leads, protective switching, and safe cooldown time after operation.

Care & Maintenance

• Keep air vents, resistive elements, terminals, and control switches clean and unobstructed.
• Inspect insulation, earthing continuity, terminal tightness, and overheating marks before use.
• Allow the unit to cool after loaded operation before handling or covering it.
• Store in a dry, dust-controlled area away from moisture, corrosive fumes, and mechanical impact.

Frequently Asked Questions

What is a Variable Resistance Load Bank 12 kW used for?

A Variable Resistance Load Bank 12 kW is used to apply a controlled resistive load for testing power sources, generators, alternators, electrical machines, and training-lab circuits.

Is the 12 kW rating confirmed?

The product name states 12 kW. The final continuous or intermittent duty rating, voltage, current, and phase must be confirmed before publishing or procurement.

How does a resistive load bank work?

A resistive load bank works by converting electrical energy into heat through resistance elements, creating a controlled electrical load for testing and measurement.

What instruments are used with this load bank?

Typical supporting instruments include voltmeters, ammeters, wattmeters, multimeters, power analyzers, tachometers, and the machine or power source under test.

Can students operate a 12 kW load bank independently?

No. A 12 kW load bank should be operated only under trained instructor or laboratory technician supervision because it involves high power, heat generation, and electrical hazard control.

What details should be confirmed before ordering?

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