DANOTHERM F2 Z2153247432 Braking Resistor

OverviewDANOTHERM F2 Z2153247432 is an aluminum housed wirewound braking resistor from Danotherm F2 series, widely used for inverter and VFD dynamic braking energy dissipation. DANOTHERM F2 Z2153247432 features 47Ω resistance with ±10% tolerance, 150°C temperature class, and compact extruded aluminum housing for efficient heat transfer. It absorbs regenerative energy generated when motors decelerate, prevents DC bus overvoltage damage to frequency converters and drive systems. This resistor is fitted with pre-wired lead cables for direct cabinet installation. In crane, conveyor, elevator and pump variable speed renovation projects, DANOTHERM F2 Z2153247432 provides stable energy dumping performance and is a standard spare for drive system maintenance.

FeaturesDANOTHERM F2 Z2153247432 adopts nickel-chrome wirewound element embedded in high thermal conductivity filling compound. The braking resistor has rugged aluminum extrusion shell with good thermal radiation and mechanical protection. It supports short-time high overload capacity matching dynamic braking duty cycles. Built without internal thermal switch by default, external thermal monitoring can be added for overheat protection. It complies with CE requirements and fits cabinet mounting with bracket installation. DANOTHERM F2 Z2153247432 is compact and low weight, suitable for limited MCC cabinet space, and compatible with mainstream brands of VFD braking units.

SpecsDANOTHERM F2 Z2153247432 dynamic braking resistor. The braking resistor series: F2. Resistance: 47Ω. Tolerance: ±10%. Temperature class: 150°C. Construction: aluminum housed wirewound. Termination: pre-wired cable leads. Mounting: bracket fixed installation. Standard: CE. It is stocked as variable frequency drive braking spare.

Operating ParametersDANOTHERM F2 Z2153247432 ambient operating temperature: -40℃ ~ +70℃. The braking resistor relative humidity: 5%~95% non-condensing. Protection class: IP00. Overload capacity: short-time peak power support for braking pulse. Surface temperature rises sharply during energy dumping, keep clear from adjacent cables and plastic components.

PrincipleDANOTHERM F2 Z2153247432 connects to the braking transistor circuit of the inverter DC bus. The braking resistor converts regenerative electric energy from the motor into heat energy during deceleration. When the DC bus voltage rises above the trigger threshold, the braking IGBT turns on and current flows through DANOTHERM F2 Z2153247432 to consume excess energy and clamp bus voltage within safe range. Long-term overheating will cause resistance drift or wire burnout.

ApplicationsDANOTHERM F2 Z2153247432 is widely deployed in material handling conveyors, lifting equipment, packaging machines, centrifugal pumps and fan variable speed systems. The braking resistor undertakes regenerative energy dissipation for AC motor drives. It cooperates with VFD braking units to realize fast stop and controlled deceleration. DANOTHERM F2 Z2153247432 is a preferred spare for drive cabinet replacement and retrofit.
