September 2012 L0105622 General Description The 34MD Series is a compact construction that implements a microstepping driver and a stepper mo- tor in one streamline package. With the two parts combined into one casing, the need to include motor wires has been eliminated. The 34MD Series has an output current capability of 1.5 Amps minimum to 10.0 Amps maximum (Peak Rating). The microstepping driver will operate off 20VDC minimum to 80VDC maximum. The inputs are optically isolated with a minimum...

September 2012 L0105623 Optically Isolated Input Pin Descriptions The inputs of the 34MD Series are optically isolated with the anode (+) and cathode (-) both brought out to the user. With no current going through the opto-diode the input is considered high. To enable the input a minimum of 1.0 mA needs to be sourced or sinked through the opto-diode. This is done simply by placing a voltage of +3.5 to +8.6 VDC across the two inputs of the opto-diode. If sourcing current into the inputs, then all...

The PSA80V4A is 80 Volt, 4 Amp power supply that will take either 110VAC or 220VAC inputs and deliver 320 Watts. The PSAM48V3.2A is a 48 Volt, 3.2 Amp power supply with a universal input to accept input voltages in the...
