The switching power is designed to be compatible with the 75 rack family and to perform ON/OFF operations on Piezo Actuators, allowing extremely fast actuations. The switching technique allows high current peaks, required by impulse applications. Only two positions can be obtained:
♦?OFF position at rest (0 or -20 Volt),
♦?ON position (150 Volt DC).
The two positions are controlled by a TTL signal. The overshoot of the Piezo Actuator can be
reduced by the electronics after some calibrations or by a current limitation or by the Mechanical Damping (MD) option on the APA®. The SP75A-x and SP75B-x can be equipped with the Push Pull option.
OEM version can be customised upon request.
