Title
You will need a power supply to power stepping motors and drivers and these 36 volt and 24 volt power supplies will deliver what the drivers and motors need.
These are our 24 volt and 36 volt power supplies. The 24 volt has an allowable draw of 10 amps and the 36 volt has an allowable draws of 8.8 amps. Both can be switched between 110/220v power. Both have terminals for plugging into the mains and have common terminals. There are also positive voltage terminals. There are DC and AC inputs. The first terminal marked L is for live. The second marked N is for neutral. The third is earth ground. Earth ground is necessary because the case is metallic. The 36v power supply has a cooling fan. The power supplies have M4 size screw holes for mounting.

  • I NEED HELP IN GATHERING PUBLISHED INFORMATION ABOUT THE RISKS POSED BY CELL TOWERS PLACED ON SCHOOL GROUNDS. THERE WHICH WOULD ENABLE ME TO GATHER/CALCULATE OR MEASURE RADIATION SPECIFIC SITE?

    The best single reference is the Federal Communications Commission (FCC) Website. Look for: Bulletin 56, "Questions and Answers about Biological Effects and Potential Hazards of Radiofrequency Electromagnetic Fields," Bulletin 65, "Evaluating Compliance With FCC Guidelines for Human Exposure to Radiofrequency Electromagnetic Fields," "A Local Government Official's Guide to Transmitting Antenna RF Emission Safety: Rules, Procedures, and Practical Guidance." An excellent technical paper with field measurements of cell-tower emissions was published by R.C. Petersen and P.A. Testagrossa in the journal Bioelectromagnetics, volume 13, page 527ff, 1992. If you need onsite technical support and services there are various consultants available, such as Richard Tell Associates, Inc. Gary Zeman, ScD, CHP Lawrence Berkeley National Laboratory

  • how do you connect the power supply to the wall?

    Use an extension cord, cut the female end off, strip off the jacket to expose the white (N), black (L) and green (earth ground). Connect the white to the terminal labeled N. Connect the black wire to the L terminal, and connect the green wire to the terminal with the circle and triangular shaped lines (the terminal that has an earth ground symbol).

  • Is a separate psu needed for each stepper driver?

    A separate power supply is not needed for each stepper motor. If the combined amps requirement is very high, I typically use more than one power supply. Say, the combined amp requirement is 18 amps, I will typically use two 10 amp power supplies. Additional Information:
