Smart-Fly SuperReg SMFREG24 User manual

Mounting
The SuperReg is mounted using the grommet and eyelets. Standard
servo screws that you would use to mount a high-torque servo work
well for this application.
Battery Charge Ports
The SuperReg has a charge port for each battery. You can run these
to external charge jacks. One caveat is that you cannot charge both
batteries at the same time through the two charge jacks, or if you
use mechanical switches, through their charge jacks either. The
reason for this is the way chargers detect the charge current. t is
detected on the negative lead which leads to a condition called
“common ground condition”. This means the two chargers cannot
determine what charge current is their charge current and can
result in charger damage or battery fires. This condition is not
caused by the SuperReg but by the fact that the ground of both
batteries end up in a common connection. This condition is
present if you used two mechanical switches into a common
receiver.
Regulator Specifications
nput Voltage Range: 5.8V to 8.5V Max
Output Voltage Range: 5.4V to 7.4V
Wattage Dissipation: 20W Continuous
Drop-out Voltage: 0.4V
BatShare on battery inputs to protect against lost cell or
shorted battery pack and to keep both batteries at equal
voltage during use when both battery packs are good.

Thank you for purchasing the Smart-Fly SuperReg!
This manual takes you through the operation and installation of
the Smart-Fly SuperReg regulator. The SuperReg provides the
user with battery redundancy, failsafe operation with remote
on/off switch and an adjustable regulator. Its dual battery inputs
have isolation between the batteries so, in case of a catastrophic
failure of one battery, the other can continue to supply power to
the aircraft. The SuperReg’s input and output power connectors
are XT-60s to handle the high current the SuperReg is capable of
handling and long-term reliability. The SuperReg’s output
voltage is continuously adjustable from 5.4 volts to 7.4 volts
(factory set to its lowest value) and can supply 7.5 amps
continuous current when the input voltage is 8.4 volts and the
regulator is set to an output voltage of 6.0 volts.
Consideration: When the failsafe switch is used to turn the
regulator on and off the regulator will draw a slight amount
of current (approximately 10mAH a day, usually much less)
even when in the off position. f you are going to let the
aircraft sit for an extended period you should unplug the
batteries from the SuperReg. f you have a 2200mAH battery
and you return home with ½ the charge left, the battery can
stay connected for at least 110 days without discharging the
battery to its maximum discharge point.

Battery nputs
The SuperReg has two battery inputs. Each input can supply 30 amps
of power to the unit. The inputs are isolated from each other so that in
case of catastrophic battery failure the bad battery cannot affect the
good battery.
The unit can be used with a single battery input if desired. The
isolation results in a 0.40V drop which results in a regulator dropout
voltage of approximately 0.50V at 7.5 amps.
The recommended way to turn the unit on and off is by using the
optional Failsafe Switch. We have several version of the Failsafe
Switch. Mechanical switches can also be use but be aware they can
cause considerable voltage drop across their contacts.
The regulator will draw a slight amount of current (approximately
10m H per day) even when in the off position when using the
failsafe switch. If you are going to let the aircraft sit for an extended
period you should unplug the batteries from the SuperReg.
Regulator Outputs
The SuperReg provides two battery outputs. The two outputs are
wired in parallel and it does not matter which output you use if you use
only one output. If you are using the SuperReg with one of the Smart-
Fly PowerExpanders, both outputs can be used to tie to the
PowerExpander to provide redundancy in the unlikely event that one
of the cables should have a failure.
Adjusting The Output Voltage
The SuperReg comes from the factory set to its lowest setting,
approximately 5.4 volts. The regulator’s output voltage is adjusted by
momentarily (less than a second) shorting one of the adjustment pins
to the center pin. This can be done with any metal object such as a
screwdriver. To increase the voltage, short the pin designated “Up” to
the center pin momentarily. To decrease the voltage, short the pin
designated “Dn” to the center pin momentarily. If you hold the pins
shorted for longer than one second the voltage will increase or
decrease at a rate of about one quarter volt a second. There are 32
steps over the adjustment range.
Power Handling Capability
The SuperReg can dissipate 20 watts continuously. The actual current
handling is dependent on the input voltage and output voltage
difference. The power calculation should use the maximum charged
voltage of the battery pack used. (7.4V packs actually charge to 8.4V,
6.6V packs actually charge to 7.2V).
Watts = ((Volts n – Volts Out) * Current)
