Test Equipment
4.1
Power Supply
Power Supply should be capable of 20 V / 25 A, current monitoring and remote sensing.
4.2
Electronic Load
Electronic load should be capable of 32 V / 7 A. Use Constant Current (CC) mode.
4.3
Meters
One current meter is required to measure input current accurately. Maximum current rating of the meter
should be carefully considered. Input current can be as high as 25 A at full load current and minimum
input voltage. Output voltage is monitored by a voltage meter which should be capable of monitoring up to
32 V.

4.4
Oscilloscope
Oscilloscope and 10x probe with at least 20 MHz bandwidth are required.

Precaution & Wire Gauge
Prolonged operation with low input voltage at full power will cause heating of the MOSFETs. A fan with a
minimum of 200LFM should be always provided.
minimum of 200LFM should be always provided.
Wire gauge for the input power supply should be 6-8 AWG minimum and no longer than 1 foot each for
VIN and GND. Wire gauge for the output electronic load should be 12 AWG minimum and no longer than
1 foot each for VOUT and GND.
