A DC voltage source for remote current programming is connected between J1-10 or J1-16 (IPROG) and the return terminal J1-23 (IP RTN). Note that the return terminal J1-23 (IP RTN) must be referenced directly to or within ±3V of the power supply common, J1-24.

  • Page 41 AUTO-STEP PROGRAMMING 4.1 INTRODUCTION The DHP series power supplies allow the user to enter a sequence of up to nine steps into memory for later execution. These steps include settings for voltage, current, OVP, and time for each step. A simple programming sequence is used. This chapter describes the use of the auto-step programming feature of the power supply.

  • Page 47 In this figure the number 230 is for example only and will vary with each supply. The “OK” means the value being read internally is within an acceptable range and the calibration may proceed. At this time read the output current using the volt meter and shunt, and using the numeric keypad enter the correct current to five places.
  • Page 48 Figure 5-7 Prepare Load Screen When the load is properly connected press ENTER. At this time the supply will output a small voltage and request that you tell it exactly what that voltage is. The display will be as shown in Figure 5-8. Figure 5-8 Voltage Calibration 1 In this figure the number 230 is for example only and will vary with each supply.
  • Page 49 Proceed with the calibration by pressing ENTER again. At this time the output voltage will rise to about 90% of the rating of the supply, and the screen displayed in Figure 5-10 will be displayed.
