PM546 Eurocard 6 Amp Stepper Drive
Eurocard Stepper Drive
The PM546 is built on the 3U high International standard extended Eurocard format. With a width of only 34 mm (7E ) up to 12 units can be fitted in single 19 in. standard Euro-rack. With adjustable current from 2.5 to 6 amps / phase, combined with chopped constant current drive technology which enables current forcing from supply voltages up to 85 Vdc, the unit provides high efficiency and optimum performance characteristics when using size 23 & 34 hybrid stepper motors.
