Brushless Tachometer

Avtron Model K661 Brushless Tach replaces analogue tachogenerators like the GE BC-42 and BC-46 or the Reliance Electric RE-210. Analogue tachs are DC Generators that put out voltage signals at 50, 100, or 200 VDC per 1000 RPM. The K661 will accept as a standard, a 240 PPR input. It can handle signals up to 24 KHz, and has a maximum voltage output of 300 VDC. The K661 has a selectable 50, 100, or 200 VDC per 1000 RPM output at 3 mA. The feedback signal is more stable and linear than the analogue tach signals with no brushes to maintain. Speed regulation is improved and routine maintenance is eliminated. When digital drives are installed in the future, the Avtron Encoder can be used to feed a frequency signal to the drive directly, thus maintaining the installation.
