ABB SNAT-609-TAI SNAT609TAI 61073779 Control Board

The SNAT609TAI is a Control Board. The maximum braking power of the braking chopper (optional). Resistor type Type designation of the standard resistor assembly. R Total resistance of the standard resistor assembly. Note! This is also the absolute minimum value of resistance allowed for the corresponding chopper. ER (pulse) Maximum energy that the standard resistor assembly will withstand. 

This energy will heat the resistor element from 40 oC to the maximum allowed.To increase the power rating of the resistor, four resistor assemblies should be used (two in series, two in parallel). However, it is not a standard solution and must be engineered separately.
