These characteristics make the resistors RDP very valuable for the applications where high reliability is required even in heavy duties as: - dynamic braking - snubber resistors - inverter - capacitor charge limiting - traction general employment The rated power of RDP is especially elevated, and this characteristic is obtained by using special materials able to withstand temperature higher than 6 C, without damage. The support bar may be supplied in stainless steel, on request. This Data sheet will provide, with the necessary pieces of information and application notes, for a first definition of a required resistor.
