The 992.0640.004 from EBM-Papst is a sensorless drive electronics – a so-called Powermodule – specially designed for the RV45-3 fan in 24 V DC version. The module controls the fan without Hall sensors and automatically limits the speed to a maximum of 40,000 rpm to protect against excessive power input during free-air operation. It is a compact and robust accessory for those who need reliable electronic control of their RV45 fan.
The module is suitable for applications where precise speed control and built-in component protection are crucial – for example, in medical technology equipment, telecom, and industrial electronics.

| Motor type | The power module is sensorless drive electronics designed for the RV45-3 fan in 24 V version. Hall sensors are not used by the module even if they are mounted on the fan. Due to the RV45's high input power during free air operation, the drive electronics limit the speed to a maximum of 40,000 rpm. The module has built-in protection against reverse polarity, locked rotor (auto-restart) as well as under- and overvoltage protection (on at 12–32 V, off at <11 V or >33 V). Internal fuse protection with Littelfuse NANO2 10 A/125 V is included. |
