We have used our heating element expertise to offer a complete range of highly compacted braking/retardation resistors with the highest performance levels. Our resistors offer the best possible performance with the smallest physical size to maximum wattage ratio due to the high level of heat dissipation.
The braking/retardation resistors can be supplied with thermal switches and safety cut outs if required and in caged or flat section.
Applications include the smoothing of power peaks for electronic speed controllers and frequency transformers in the manufacturing industry, electrical industry, apparatus construction, inverters, speed controllers markets.
Power resistors are designed to smooth peaks within electronic circuits. Due to the highly compacted construction the resistors have a good thermal conductivity. The heat generated within the resistor is easily conducted to the outer sheath and also in case of restricted space a maximum discharge of energy is reached. Turk and Hillinger supplies power resistors in 4 types of construction:
The extremely flat profile of the FBW resistor enables installation in confined spaces. The large surface area enables the resistor even when used on frequent braking sequences to perform without overheating.
For permanent wattages from 400 W to 800 W there are 2 or 3 ALW 80 resistors with an overall length of 300 mm or 400 mm mounted on sheet metal brackets and wired in parallel within a connection box. The permissible permanent or peak wattages are 2 to 3 times higher than the permissible wattages of the single resistors, as well as the other technical data.
The connection box is of protection degree IP 23.
The connection lead can be passed into the housing through a grommet.
For higher power ranges the grouping of several ALW 90 is possible. The permissible permanent or peak wattages are calculated over the total profile length. The connection box is of protection degree IP 65, on request it is also possible to supply a lower protection degree.
The RHK type power resistors are designed for the smoothing of performance peaks for electric and electronic circuits at permanent performances higher than 800 W (e. g. escalator controls) . These resistors consist of one or several tubular heaters ø 8,5 mm with a stainless steel sheath which are assembled into a housing of zinc plated perforated sheet metal. Upon request the resistors can be supplied with an optional thermostat to control the maximum sheath temperature of the resistors.
For special cases of operation the power resistors type RHK can be supplied with an incorporated splash proof enclosure with protection degree IP 54. The resistors are wired in parallel.
