Jolly Driver
Mosfet and IGBT drives for D.C. motors
Product description
The drives of the Jolly series are used for controlling servomotors on the most frequently used power ranges. The drives are of a compact size and can be easily installed and offer high reliability.
A final P.Mos or IGBT stage is provided which is controlled by a PWM signal having a switching frequency of 20 kHz.
The Jolly drive is provided with a power supply unit and an
internal clamp, a switch for the selection of the speed (using
dynamotachometer or feedback from armature) or of the
torque characteristics and also acceleration and deceleration
ramps.
The terminal strips and the adjustment trimmers are arranged on the front panel and permit easy mounting also in multi-axis systems.
