| Extra info for you |
- Module works from 8 to 15V, but 9V is optimal choice. Why?
This module contains two regulators, which converts:
a) Input Voltage into 5V DC and
b) Input Voltage into 180/150V DC.
If you use 8V Input Voltage, it's good for linear 5V regulator, as
dropped voltage is small, not too much power disrupted and
your 5V regulator does not heat up, but high Voltage converter doesn't
have enough output current for your Nixie Tubes due to limited input
power.
If you use above 12V Input Voltage, it's NOT good for conversion into 5V, as
dropped voltage is too high (for 13 V input it's 13-5=8V), too much power
disrupted and your 5V linear regulator heats up even your
circuit consume low current, even 100mA at 5V output will waste more
than 0.8W of your input energy!
But It is reasonably good for your high Voltage converter as it does
have
enough power to produce more current for more or bigger Nixie Tubes.
I do provide you technical specification on BOTH outputs, so you
can clearly see what you will get!
9V is great optimal choice !
- I would not recommend to use above 12V to power up my or similar
module build with linear 5V regulator! It ates an extra
energy and heat up the circuit!
In 99% cases 9V or12V is good choice and enough power for your Nixie
Clock. Please have a look at my Nixie Clock prototype on Picture 1, where 6
IN-14 Nixie Tubes are powered by my Nixie Power Module.
On the Picture 4 you can see my Nixie Clock on IN-12B tubes, where I
used the same Power Supply circuit !!
- If you need to get more current from 5V regulator,
the module design ALLOWS you easily attach heat sink to
the 5V regulator - just simply bend 7805 regulator back into its
vertical position and easily fix an heat sink to it.
Also I would recommend you to do it if you use 12V
input at 5V output with current greater than 100mA.
- To reduce the power disruption and to keep your circuit at high
efficiency level, it's easy to use two or more modules in
your project, if for example, you have big Nixie Tubes or when you need to power
up more than 6 medium size tubes. Connection diagram example
to power up 10 Nixie Tubes with 2 module will be provided to
you on your request.
- My recommendation: do not apply maximum current to your Nixie
Tubes, use value just above middle of available range. For
example, IN-14 and IN-12 Nixie tube's max recommended current is
2.5mA, so in my Clock I use 1.5mA per tube. It's optimal choice
between good brightness, power consumption and tubes life
time. Simple calculation shows that 6 Nixie Tubes will require only
9mA, which my Power Supply Module can easily provide!
- Picture 1 and 2 also shows you how easy to use this module on
your solderless bread board when you are just designing your circuit
!
- Module has only 6 solder pads to connect your wires or pins, but
some pins are duplicated for your extra flexibility in your circuit
layout design. So only 4 solder pads in use, no switches, no
extra connectors are required!
- The Power supply Module Circuit is reliable and very easy to
build, I do provide the Circuit Diagram, so please feel free
to use it in your projects !
- I am proud that my ideas and recommendations are useful and used
by my Customers or even by my competitors! Sometimes
it's not easy to choose the right solution for your project, so
please feel free to ask me.
- Please note, that power module shown on
Pictures 1, 2 and 3 is first HW release, but you will get next
generation V.02 hardware release, which has exactly the same
technical specification, but smaller size and extra improvements -
like wrong polarity and over current protections.
