The Resistive Load Bank Unit is an electrical testing apparatus used to apply a controlled resistive load to a compatible power source. It is intended for engineering laboratories, polytechnics, technical institutes and supervised workshops that need to study source regulation, voltage drop, current delivery, power output and load-dependent performance.
Product Description
The STEMAids Resistive Load Bank Unit contains resistance elements arranged to absorb electrical power from a connected source. The absorbed energy is dissipated primarily as heat, allowing students and technicians to observe how batteries, generators, power supplies or other compatible sources perform as the load changes.
Depending on the supplied configuration, load may be selected through switches, terminals or stepped resistance sections. The unit can support voltage, current and power measurements under controlled conditions. Its voltage class, power capacity, load steps, duty cycle and cooling requirements must be confirmed before operation.
Key Features
- Controlled resistive loading: Applies a defined electrical demand once the load values are verified.
- Source-performance testing: Supports observation of voltage regulation and current delivery under load.
- Selectable load operation: May provide stepped or switchable load sections according to the supplied model.
- Quantitative experiments: Enables voltage, current, resistance and power calculations.
- Reusable laboratory equipment: Supports repeated technical exercises within confirmed thermal and electrical ratings.
- Practical fault analysis: Helps users identify excessive voltage drop, weak sources and unstable output.
- Training-focused design: Suitable for electrical machines, power electronics and battery-testing instruction.

How to Use the Resistive Load Bank Unit
- Confirm the source voltage, load-bank rating, duty cycle and cooling requirements.
- Place the unit on a stable surface with ventilation openings unobstructed.
- Set every load switch to the off or minimum-load position.
- Connect the source using correctly rated leads and verified polarity.
- Start the cooling system where the unit uses forced ventilation.
- Energise the source and apply load in approved increments.
- Monitor voltage, current, temperature and operating time continuously.
- Remove the load, switch off the source and allow the unit to cool.
Safety note: A load bank can become extremely hot and may draw high current. Use trained supervision, suitable protective devices and correctly rated cables. Never exceed the confirmed voltage, power, current or duty-cycle limits.
Care & Maintenance
- Allow the unit to cool fully before handling, cleaning or storage.
- Keep ventilation paths, fans and resistance elements free from dust and obstruction.
- Inspect terminals, switches and cables for overheating or mechanical damage.
- Verify load-step resistance and protective functions periodically using suitable test equipment.

Frequently Asked Questions
What is a Resistive Load Bank Unit used for?
It is used to apply a controlled load to a power source and evaluate its voltage, current, power and regulation under operating conditions.
What equipment can be tested with the load bank?
Compatible batteries, generators and power supplies may be tested. Suitability depends on matching the source with the confirmed voltage, current and power ratings.
Does the load bank support AC and DC testing?
AC and DC compatibility is not confirmed. Use the unit only with the supply type stated on its approved specification and electrical label.
What is the load capacity?
The total wattage and individual load steps are not confirmed. These values must be verified before connecting a source.
Why does a resistive load bank become hot?
The resistance elements convert absorbed electrical energy into heat. Adequate cooling and clearance are therefore essential during and after operation.
Can the unit be operated continuously?
Continuous operation is permitted only if the verified duty rating allows it. An intermittently rated unit must be operated within its specified load and cooling cycle.
