PITKIN POWER CONTROLLER OPERATING INSTRUCTIONS 2
2nd Gen Pitkin Controller
The 2nd gen Pitkin Controller can be used to adjust
the power on a heated vest, habitat scrubber, or
other battery powered device. The power controller
is connected inline between the battery pack and
the powered device using e/o cords and uses tap
or switch control to select one of six power settings
(0, 20, 40, 60, 80, or 100%). An LED indicates the
current power setting. The power controller is rated
for 5-24 v input but doesn’t regulate voltage at a
constant output so divers must verify the heated vest
or device being powered can handle the battery
voltage. The power controller is rated for 10 amps
at any voltage.
CAUTION: When connecting the power
controller, be sure to connect the e/o cord with
the red band to the power supply. Failure to do
so may result in damage to the controller.
Output Level
The LED flashes indicate power output level.
Flashes Power Level
5 100%
4 80%
3 60%
2 40%
1 20%
0 Off
Tap Control
The LED flashes red every time a tap is detected and
flashes an equivalent number of flashes after 5, 6,
or 7 taps are detected (less than 1/3 second apart).
Taps Function
3 increases power
2 decreases power
5 sets tap sensitivity (see below)
6 toggles power interruption control
(see below)
7 toggles between standard suit heater
mode (blue LED) and motor control
mode (green LED, see below)
PITKIN POWER CONTROLLER OPERATING INSTRUCTIONS 3
Set Tap Sensitivity
• 5 taps LED indicator changes to red.
• Adjust tap sensitivity from level 0 to 5 using 2 or 3
taps. Most people can leave at the default 100%.
• 5 taps to save and exit.
• Tap sensitivity is always at 100% for 5 seconds
after the controller is powered up to allow this
menu to be entered.
• Output power is switched off while tap sensitivity
is being adjusted.
Power Interruption Control
• Briefly interrupt (off/on) the power to go down
one power level.
• Switch off for 3-5 seconds to revert to full power.
• This mode can be enabled/disabled by 6 taps.
Motor Control Mode
(for habitat scrubber fan motors)
• Uses higher frequency (20kHz) pulse width
modulation (PWM) and different power settings
optimised for that purpose.
• Much less efficient for heat control than suit
heater mode which uses 20Hz PWM.
• Switch between motor control (green LED)
and suit heater mode (blue LED) with 7 taps.
