Braking Resistors - Power Resistor

 

Braking Resistors

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 Resistor

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:

  • High density cartridge heaters type HLP (see leaflet HLP, but with a dielectric strength up to 4100 V DC)
  • Aluminium power resistors type ALW 40, ALW 70, ALW 80, ALW 90
  • Flat brake resistors with steel housing type FBW
  • Power resistors type RHK

Through the highly compacted construction

  • High thermal capacity
  • High durability
  • 100% vibration resistance
  • Optimum heat dissipation from the resistance wire over the sheath surface to the environment
  • Higher power capacity compared to uncompacted resistors

General Items

  • Electrical safety
  • Easy mounting
  • If required the power input can be increased arbitrarily through serial or parallel connection of the power resistors

Intrinsic Safety

On request the power resistors ALW can be fittet with an unique patented internal thermal fuse. The thermal fuse will activate if the resistor experiences critically high temperatures. The maximum voltage is 970 V DC for ALW70, ALW90 and FBW resistors. If an internal thermal fuse is fitted then the maximum surface temperature may need to be reduced depending on the individual application.

ALW 80

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.


ALW 90

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.

Power Resistor RHK

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.
