Leistungswiderstand PWR O

PWR-O with aluminium housing

This wire resistor with an aluminium profile combines the high pulse stability of tried-and-tested wire materials with optimised thermal conduction and a high degree of protection. Mounting on a thermally conductive surface further improves heat dissipation and increases stability. The product satisfies the requirements of UL508.

Connection lines available in various lengths and materials. Optionally available with integrated temperature switch. Also available as a customer-specific assembly on request.
