CDH
The CDH belong to our range of ALPHA ALUMINIUM HOUSED COMPACT BRAKE RESISTORS.
The CDH resistors are insulated and constructed in small dimensions so that they fit into compact constructions.
The resistor elements are wirewound helix elements mounted in and supported by a ceramic insulator.
The flat construction of CDH makes it ideal for heat sink cooled equipment.
The CDH resistors are available in two different protection degrees; IP50 and IP56.
