DC Tachometer Generators Feature Low Ripple

Servo-Tek low-ripple tach generators satisfy the need for a low-cost, very low-ripple tachometer. In addition to being the first economical low-ripple units of their type, Series F and H tachs incorporate all the desirable features of the Servo-Tek generator line-temperature compensation, long brush life, excellent linearity, etc. As shown in the spec sheet table, ripple voltage does not exceed 1.5% rms/p-p 3.5% max.
