Custom Resistive Load Banks
Custom Resistive Load Banks, Built Around Your Test Requirement
A resistive load bank converts electrical energy directly into heat through resistive elements, creating a purely resistive load at unity power factor. That makes it the most accurate way to prove out real-power (kW) performance of a generator, UPS, inverter, transformer, or battery system the way it will actually behave once it's in service, not just on the nameplate.
At HTR, no two load banks are the same. Every unit is engineered to the customer's voltage, power rating, step configuration, cooling method, and form factor.

The control architecture — manual selector, multifunction metering, or PLC/HMI-based automatic step control — is chosen to match how you actually run the test, not the other way around.
Applications Across Every Power Testing Environment
Our custom resistive load banks are deployed across power generation, energy storage, industrial systems, transportation, and data-centre infrastructure. Typical use cases include:
Generator & Genset Commissioning
Verify rated capacity, voltage stability, frequency response, and fuel consumption under real load, not a bank of light bulbs or a shorted output.
UPS, Inverter, SMPS & Stabiliser Testing
Validate output voltage, current, thermal behaviour, and transfer performance under step-wise or sustained load conditions.
Battery & Energy Storage Validation
Measure actual vs. rated discharge capacity, characterise charge-discharge cycles, and confirm real backup runtime.
EV Charging & Battery Pack Testing
Simulate real charging demand to validate metering accuracy, safety interlocks, and thermal performance of EV infrastructure.
Meter, CT, Relay & Switchgear Calibration
Apply precise, known loads to calibrate and type-test energy meters, current transformers, relays, and switchgear.
Full-System Load Testing
Exercise the complete generator → ATS → UPS → distribution chain as a connected system, not as isolated components.
Solar Inverter & Renewable Energy Testing
Validate grid-tie inverters, hybrid solar systems, and off-grid power converters under controlled load profiles that replicate real-world demand.
Data Centre & Mission-Critical Commissioning
Prove full-facility power capacity, redundancy, and cooling behaviour before live IT load arrives — dark testing on gensets, UPS strings, PDUs, and busways.
