Frequently Asked Questions
What is the purpose of this braking resistor?
The braking resistor is designed to dissipate energy generated during the deceleration of electric motors in applications such as variable speed drives. It helps in quickly stopping the motor by absorbing the excess kinetic energy and converting it into heat.
Can this braking resistor be used for continuous operation?
The braking resistor is capable of continuous operation with a power rating of 900 W. However, it is primarily intended for intermittent use where occasional high braking power is required, such as emergency stops.
What are the dimensions of the braking resistor?
The dimensions of the braking resistor are 134 mm in width, 350 mm in height, and 203 mm in depth.
What is the resistance value of the braking resistor?
The resistance value of the braking resistor is 33.3 Ohms.
What is the peak power capacity of the braking resistor?
The peak power capacity of the braking resistor is 18 kW.
How should the braking resistor be installed?
The braking resistor should be installed ensuring that it is resistant to ground faults and short circuits. It should not be mounted close to drive equipment if it is loaded with continuous power for prolonged periods, but rather outside the control cubicle.
What is the thermal time constant of the braking resistor?
The thermal time constant of the braking resistor is approximately 1600 seconds.
Does the braking resistor come with a temperature switch?
Yes, the braking resistor is equipped with a temperature switch that responds to thermal overload due to high ambient temperatures.
What is the operating voltage range for the braking resistor?
The operating voltage for the braking resistor is less than 850 V DC.
What safety precautions should be taken when handling the braking resistor?
When handling the braking resistor, it is important to ensure that it is not touched during operation as it becomes very hot. Additionally, ensure that the installation and unit are disconnected from power before starting any work.
