• quick connection
• adaptation to any frequency inverter
• good power to size ratio
• optional with cover and temperature switch
• optionally also for aggressive environments (e.g. salt mist)
• protection type: IP66

TYPICAL APPLICATIONS

Braking resistor for drives with frequency converters of medium to high power. Mounting inside and outside the control cabinet is possible.

SERVICES

• degree of protection: IP20 / IP65 / IP66
• test voltage: 2.5 kV AC
• ambient temperature: 10+40 ºC
• other services on request
• other fastenings on request
• optional with external cooling

In the event of destruction, the resistor becomes high-impedance. Each series is available with a temperature switch.  The specified performance values were measured at a horizontal position of the resistors in the air with a distance of min. 100mm to the substrate. The power values refer to the standard products with a normal tolerance of +/- 10% at an ambient temperature of 20°C.

*With small resistance values, the conductor cross-section is adapted to the current
