Safe brake resistors for electric drive technology are subject to specific requirements. High pulse load capacity with controlled surface temperature including a conclusive safety concept with continuous overload is required.
Taking all parameters into account, we achieved an optimum with our safe brake resistors in wire-wound technology in the power range of 60 – 400 watts has achieved an optimum. In compliance with relevant standards, subcomponents were selected and installed in a stable, anodised aluminum housing by means of specific design measures.
The result is something we are proud of: Particularly impulse-resistant, low-induction resistors with a specific safety concept combined with a long service life.
With four mechanical and electrical ranges of 35, 70, 105 and 140 watts continuous power on a heat sink, the PTC brake resistors cover the power requirements of small frequency inverters and servo controllers.
