Description The second-generation CoolSET™-F2 key offers several special improvements to meet the need for low power standby and protection functions. Reduced shifts in standby mode are used to reduce power consumption and support this mode with a stable output voltage. The limited frequency is reduced to 20kHz/21.5kHz to avoid noise. In case of failure mode open loop, overvoltage or ...
