LUST LTi Drives ALW80 BR-200.02.540.UR Brake Resistor
Product Overview
The LUST LTi Drives ALW80 BR-200.02.540.UR is an industrial braking resistor identified by its model designation and ALW80 housing reference. The supplied product information specifies a power rating of 150 W and a resistance of 200 ohms. These values are important for identifying the component and assessing its suitability for a compatible drive system.
A braking resistor dissipates electrical energy generated when a motor decelerates or operates regeneratively. In a drive system equipped for resistive braking, regenerated energy is directed into the resistor and converted into heat. This process helps manage DC link voltage during braking and can support controlled deceleration when the drive and braking circuit are designed for the application.
Resistance and Power Rating
The 200 ohm resistance is a critical selection parameter. The resistor must match the permitted resistance range of the drive's braking circuit. An unsuitable resistance can result in excessive current, limited braking performance or faults in the connected equipment.
The listed 150 W rating describes the specified power class, but actual performance depends on braking duration, repetition rate, ambient temperature and installation conditions. Peak braking power and continuous power are not necessarily the same. The applicable technical documentation should define the permitted duty cycle and thermal limits.
ALW80 Housing and Integration
The ALW80 designation forms part of the product identification and should be retained in maintenance records. Confirm the housing dimensions, mounting arrangement, terminal configuration and thermal requirements before installation. Do not infer unverified mechanical dimensions or protection ratings from the housing designation alone.
The resistor must be used with a compatible drive and braking circuit. Check the drive's DC bus conditions, minimum permitted resistance, braking current and recommended protective arrangements before connecting the component.
Industrial Applications
Braking resistors are used in industrial equipment where motor deceleration produces regenerative energy. Depending on the system design, applications may include automated machinery, positioning systems, handling equipment and production processes that involve repeated changes in speed.
Installation and Thermal Safety
Braking resistors generate heat and may reach high surface temperatures. Install the component according to the manufacturer's requirements for mounting, ventilation, clearances and cable protection. Keep heat-sensitive materials away from the resistor and provide any specified thermal protection.
Before servicing the drive, isolate the power supply and follow the required DC link discharge procedure. Stored electrical energy can remain after the supply has been disconnected. Installation and maintenance must be performed by qualified personnel.
Maintenance and Selection
Inspect the housing, terminals, wiring and mounting points for signs of overheating, damage or loose connections. Confirm that the drive's braking parameters remain appropriate for the installed resistor.
The LUST LTi Drives ALW80 BR-200.02.540.UR is identified by its 150 W and 200 ohm specifications. Final selection should also verify the applicable voltage rating, braking duty and compatibility with the drive's braking circuit.
