corrected before moving forward. Reset the handheld controller pulsewidth (PW)
to 0, and unplug the Resonator Power AC power cord. Allow 60 seconds to pass
for the onboard capacitors to discharge before proceeding to the next step.
22. In this step, we will increase the max current limit of the current protection
circuitry to its nominal operating level. First, the Control Power AC power cord
should still be plugged in and handheld controller OFF with pulsewidth (PW) set
to 0. Using a multimeter, monitor the voltage across capacitor, C25, while
adjusting potentiometer, R23.
Set the voltage to 2.0V
. This sets the max current
limit to approximately 250A.
23. At this point, we are ready to start final testing and tuning of the microBrute
Tesla coil. The following instructions procedure shows the proper power-up and
power-off sequences recommended for the microBrute DRSSTC. For the
remaining portion of these instructions, the term “power-up” refers to the power-
up sequence described below and the term “power-down” refers to the power-
down sequence described below.
COOLING FAN WARNING
The supplied cooling fan must be used with this device at all times.
NEVER operate the microBRUTE DRSSTC system without a cooling
fan!
POWER-UP Sequence
a. Ensure you are at least five (5) feet away from the microBrute
DRSSTC, that you are wearing both eye and hearing protection, and there
is a break-out point installed on the Tesla Coil.
b. Position fan to blow air across heatsink and turn-on.
c. Set the handheld controller pulsewidth (PW) to 0.
d. Set the handheld controller PRF to 50%.
e. Turn the handheld controller ON.
f. Plug-in the Control Power AC power cord.
g. Plug-in the Resonator Power AC power cord.
