 PD-E Series
EMC Compliance Packaged Ministepping Systems

The highly-successful PD Series, featuring 4000-step resolution and a universal “go anywhere” power supply, has now been extended with the addition of a CE-marked version. This version complies with the European Union’s EMC and Low-Voltage Directives, requirements for products to be sold in Europe. Available either with a step-direction input or with a powerful built-in indexer, the drive incorporates all necessary line filter components—no external add-on units are required.

The PD-E Series features a 70VDC bus, a peak output current of 3A or 5A/phase and 4000 step/rev resolution to give smooth rotation at all speeds. The drive operates from all AC supply voltages in the 100-240V range without adjustment. This is achieved using an integral switch-mode power supply that incorporates power factor correction. There is extensive built-in protection to guard against overheating, short circuits and supply faults. For applications requiring rapid deceleration of high-inertia loads, an alternative version is available with a built-in regenerative power dump.
