d-Drive/Modular
EVD 50
Product Description
The EVD 50 is a digital amplifier designed for low voltage piezoelectric actuators as part of a d-Drive modular system. It is designed for 19″ rack mounting. The permanent output current is 50 mA.
Actuators with a high electrical capacitance can be driven very fast and with a short rise time. The closed loop-version of this amplifier with ASI-function (Automatic Sensor Identification) can be used with strain gauge or capacitive feedback sensors without additional modification.
The DSP (digital signal processor) is 64 MHz, the sampling rate is 20 µsec, and the effective resolution is 20 bit.
The advantage of the free interchangability of calibrated digital actuators, makes the EVD 50 suitable for use in high accuracy positioning applications in the semiconductor industry, biological research, fiber alignment, metrology and many other applications.
As part of a d-Drive modular system, an EVD amplifier works with an EDS interface inside of a d-Drive modular case.

FAQ
How do I choose between open-loop and closed-loop versions?
Choose closed-loop when you need absolute positioning accuracy and repeatability (e.g. measurement, alignment). Open-loop is more cost-effective and responds faster when you only need relative fine motion or scanning, or when your system already has its own feedback.
Can I test the unit before deciding?
Nahshon is the exclusive distributor of piezosystem jena in Taiwan and keeps commonly used demo units available for scheduled testing, with Chinese-language selection support and direct access to factory engineering.
How do I confirm pricing and lead time for EVD 50?
Add EVD 50 along with your stroke, load and accuracy requirements to your inquiry list, and we'll help confirm the selection and reply with the factory quote and lead time.
