C40 - 40 Amp, Diversion or
in a single gang switch box (included)
12 volt systems
diversion controller has most of the features of our larger controller,
but is much more compact and economical due to to the fact it is
specifically designed for 12 volt systems.
Some of the key features of this controller are:
- Microprocessor controlled -- This is
very important for both stability and functionality.
- User changeable settings -- Several
controllers on the market set the dump level, and that's that!
- High amp rating - 40 amps with the one
included relay -- You may add more if you need more amps.
- Battery status LED - Several
controllers do not tell you what's going on - This one does!
- Push to test. Ever wonder if your
controller & load are working OK?
- Steel enclosure. This compact unit mounts in a
standard outlet box (included).
- Long leads for easy termination.
- Can divert the source from the
batteries to the load, or dump both the batteries along with the source.
Some specifics about the points made above.
microprocessor is the heart of the controller. It is given the
battery voltage and the user changeable trip points. This information is
analyzed and acted upon.
The Battery level
is checked, and based on that info, the Green LED flashes or is illuminated as follows
- (One) Flash indicates the battery is less than 12 volts (12
volt system - Double for 24 etc)
- (Two) Flashes indicates the battery is 12 to 12.5V
- (Three) Flashes indicates the battery is
12.6 to 13v
Flashes indicate the battery is 13.1 to 13.5V
- ( Five) Flashes indicates the battery is
above 13.5V but less than 13.9V (Settings are adjustable)
green means the battery is full.
The red LED is illuminated when the
battery is being dumped at 14.5v (or the charge source diverted.)
The dump remains active
for a minimum of 5 seconds, at which time it is checked by the
microprocessor. If battery voltage drops below the "Dump Cancel " level,
the dump is disabled, otherwise the dump is continued and rechecked
every 5 seconds.
When you click the "TEST" push-button - the 5 second cycle is
started (one time, unless the batteries are within the "Dump Start" and
"Dump Cancel" zone.)
are user changeable!! By simply turning a simple potentiometer with a
small screwdriver, you can quickly adjust the trip point.
High amp rating -- 40
Amps as configured! -- This is a respectable controller.
There is nothing stopping
you from adding more relays for nearly an unlimited amount of load
capability.The internal regulator can handle 4 relays (additional
relays are available on our site.)
The enclosure is heavy
gauge, solid steel - Ready to mount. -- No plastic, no junk, simple and
About load diversion.
The basic operating
philosophy of a diversion controller is quite simple. Monitor the
battery voltage, and if it should rise to a predetermined level,
connect a diversion load (or "Dummy Load"), of sufficient size, to the
battery or energy source to prevent the battery voltage from increasing
any further. This is a very simple, yet very effective way of preventing
battery overcharging. All alternate energy systems should have some
form of battery overcharge protection.
Several schools of thought on the subject.
- The source of power (wind turbine, solar
panels etc.) -- should remain connected to the batteries while the dump
source should be diverted to the load directly and disconnected from the
We happen to believe that is far better to leave the
wind turbine connected to the batteries at all times. Why? When you
remove the battery level voltage from a wind turbine and send it's power
directly to a load, then it sees for all practical purposes a short
circuit (depending on the resistance of the load and lead wires.) This
may cause the turbine blades to slow dramatically and in some cases
bring it to a halt. This braking action can cause heat build up in the
stator if it is repeated every few seconds or so (if the battery is just
a little over the top). When you allow
the turbine to see the batteries, along with the load, the turbine
remains more within it's design realm -- always a good thing.
The internal relays are configured to dump the batteries along
with the source, but if you desire to disconnect the source from the
batteries and send it to the load directly, simply utilize the N/C
contacts of the relays as well. See the wiring diagrams below for
compare this controller to others.
Do they have battery status indication?
Do they have a dump active indication?
Are the dump levels user changeable?
- Are they microprocessor controlled?
- Do they come with a enclosure?
Can they truly pull in multiple relays
without burning up or do they need fans?
Do they handle the amperage you need?
Do they have a dump test capability?
When you compare this controller to the others, you
will see why we built it and why we know you'll love it.
