Microprocessor-based digital potentiometer

The DP4 Series Digital Potentiometer from Dart Controls is now RoHS compliant. The product is suitable for new equipment, as well as retrofitting most ac or dc drive systems where precise, repeatable speed setting and digital readout are desired. DP4 will also support bipolar connections with power supplies of +/- 10 V dc or lower for regenerative or standard relay reversing control applications.
