9、 Application scenarios
industrial robot
Used for the braking circuit of robot joint servo motors, absorbing braking energy and protecting the driver.
Elevators and lifting equipment
As an energy consuming braking resistor in the elevator control system, it achieves fast start stop of the motor.
Uninterruptible Power Supply (UPS)
During the testing phase, as a load component, verify the stability of UPS output.
New energy equipment
Used for soft start current limiting in photovoltaic inverters to prevent device damage from surge currents.
test and measurement
As a standard load in the laboratory, it is used for power supply and battery charging and discharging tests.
