Wide-voltage Constant Power Load Banks
Working Principle
A performance-focused load type that can utilize air or liquid cooling and operate in either dissipative or regenerative modes. Its core features are "wide voltage range" and "constant power" operation.
Wide Voltage Range: Refers to a single load module’s ability to operate across a broad input voltage range, linearly adjusting resistance to maintain constant power consumption.
Wide-voltage Constant Power Load Banks Key Features
- High testing flexibility: A single load can cover testing for multiple devices from low to high voltage without frequent hardware changes or reconfigurations.
- Simplified system configuration: When testing devices with wide voltage variations (e.g., batteries discharging from full to empty), there is no need to configure redundant modules to meet peak voltage requirements, saving costs and rack space.
- Protection for the device under test: In constant power mode, the load automatically increases current as voltage drops to maintain power, which better simulates real-world load characteristics and tests the dynamic response of power supplies.
Typical Applications of Wide-voltage Constant Power Load Banks
Battery testing
Charge/discharge testing of power and energy storage batteries, which experience significant voltage changes during testing.
Testing of wide-voltage output power supplies
such as programmable or specialized power supplies.
ELectric vehicle whole-vehicle or component testing
Simulating load conditions under real-world voltage fluctuations.
