signals (the GND will become the positive supply, and -
VINA and -VINB will become the new GND). Here, both
supplies must be the same voltage.

Users have the option to change components and
substitute alternate loads. UV is set at 37V.

LOAD Board (R and C Loads; Fig 8)
• Edge connector pins plug into Control board
• Typical Load current is <100mA (limited by power
• Two load resistors for each channel; one ~80mA, 2nd
• Switches to connect the loads in and out
• Multiple holes for soldering wires, pins, posts, for external
• Holes for optional load caps
• Power Good signal from each channel brought over
• LED Channel “ON” indication
-48V Hook-Up Instructions
NOTE: If the user substitutes higher current external loads, the
power supply capability would need to be increased accordingly.

needed per channel; 0.5A total). A positive supply can
also be used as long as the user keeps the polarities
correct. The two channels can share one voltage supply,
can each have their own supply, or can even have two
different voltages (no special power-up sequence is
needed). If only one channel is being tested, the other
can be left unconnected. The following instructions are
the same for both channels. As shown in Fig. 3, A1 is an
optional ammeter to measure current; V1 is an Voltmeter
to measure power supply voltage, and V2 is a voltmeter
to look at other signals. Note that the voltmeters are
referenced to the negative supply rail.
