2.1.3.1 Input Connections

  1. Prior to connecting the DC input source, set the current limit of the input supply to 0.1A maximum. Make sure the input source is initially set to 0V and connected to the VIN_SNS and GND_SNS connection points as shown in Figure 2-1.
  2. Connect EN DC source and set the current limit of the input supply to 0.1A maximum. Make sure the input source is initially set to 0V and connected to the EN and GND_SNS connection points as shown in Figure 2-1.
  3. Connect voltmeter 1 at VIN_SNS and GND_SNS connection points to measure the input voltage.
  4. Connect ammeter 1 to measure the input current and set to at least 1-second aperture time.
