4.2 Test Equipment

Power Supply: Connect to VIN(-) and Ammeter1. The power supply must be capable of supplying 16 A. Adjustable voltage range must be from 3 V to 36 V.

Multimeters:

  • Voltmeter 1: Measure the input voltage at VINS+ to VINS–.
  • Voltmeter 2: Measure the CH1 output voltage at VOUT1S+ to VOUT1S–.
  • Voltmeter 3: Measure the CH2 output voltage at VOUT2S+ to VOUT2S–.
  • Ammeter 1: Measure the input current. Connect to the power supply and VIN(+).

Electronic Load:

  • Load 1: Connect to VOUT1(+) and VOUT1(-). The electronic load must be capable of sinking 6 A.
  • Load 2: Connect to VOUT2(+) and VOUT2(-). The electronic load must be capable of sinking 6 A.
