The
PST-SR700-6 DC/DC converters are useful for voltage conversion to operate 12
volt negative ground electronics off 6 volt, positive ground vehicles, best for
radios, stereos, DVDs, CB radios, transmitters. They might not applicable to
motors, ignition coils, or solenoids, further testing is necessary.
Motors: Running motors from these
units will void the warranty.
This is a 6 volt dc to 12
volt dc converter. These are Boost Converters. For semi-custom applications you
can specify any output voltage from 10 to 15 volts with a minimum order of 10
pieces. They can be adjusted between 13.8 and 11.2 volts with an internal
pot.
The PSTC-0624012 is an exciting new 250 Watt DC converter that
can be used with either negative ground or positive ground cars. Negative
ground cars like vintage Volkswagens and Porches can now run 12 volt
electronics.

| Remote (Key) control |
When the on-off switch
is turned "off" the power supply can be turned on by applying 4.5-8.4 VDC to
the "power control" terminal. |
None, an external
switch or relay capable of handling 60+ amps must be used. |
| Cable |
Note that if you are drawing 180 watts from the PST-DU700-6 the
input will be 30 amps. This requires a large cable, 8 to 10 AWG or bigger, as
short as possible. For the output 10 to 14 AWG is recommended, but it can be
smaller depending on your cable length and actual intended power
draw. |
Note that if you are drawing 240 watts from the PSTC-0624012
the input will be 55 amps. This requires a large cable, 6 to 10 AWG or bigger,
as short as possible. For the output 10 to 14 AWG is recommended, but it can be
smaller depending on your cable length and actual intended power
draw. |

Note: For the PST-SR700-6, in order to
convert the positive ground to negative ground, the output ground and the input
ground are at the same potential. This makes the potential difference between
the -6 volt terminal of the battery and the +12 volt output of the convert a
total of 18 volts apart.
For the PSTC-0624012 the outputs are fully
isolated from the inputs so you can connect the negative output to the car
chassis whether the car is a positive or negative ground.
Q/A
Q:
My PST-SR700-6 shuts itself off.
A: The main cause of this is over
temperature. This can come from putting the unit in the engine compartment, but
it can also happen in places like Phoenix, Arizona where the car is left in a
parking lot to bake.
This can also come from trying to draw too much
power from the unit. A stereo rated at 180 watts will draw much more than 180
watts from the 12 volt line because of inefficiencies in the amplifier. You may
not be able to turn the stereo to these kind of noise levels without the DC
converter shutting itself off.
Our engineers say that an amplifier that
is rated for 180 watts output to the speakers will draw about 410 watts from
the 12 volt supply.
The two effects add to each other. When the ambient
temperature is high the SR700-6 dc converter will shut off at lower
decibels.
Q: Can the PST-SR700-6 be used with 6 volt cars that have
negative ground.
A: Not easily. You would have to isolate the stereo system
from the car chassis everywhere. People have done it, but it isn't easy.
However, the PSTC-0624012 works with either negative ground or positive ground
cars.
Q: I have a 6 volt negative ground car and I want to run 12 volt
windshield wipers, I tried the PST-SR700-6 and it works.
A: It is because
you are driving the wipers at 18 volts. This may wear out the wiper motors
faster, but it does work.
Installation of the
PST-SR700-6
Input: Hook up the plus and minus inputs as indicated on
the front panel. Since this is for positive ground cars, hook the plus input to
the chassis ground and the minus input to the minus or "hot" terminal of the
battery. The frame of the PST-SR700-6 is isolated from all inputs and
outputs.
The remote switch terminal is in the center. If the rocker
switch is turned OFF applying -6 volts to this terminal will turn the DC
converter on.
Output: Take the minus output and ground it to the car's
chassis. Take the plus output and attach it to the radio.
Mounting:
Mount the PST-SR700-6 in a place that will be free from dust and spray. Use
large cables for the input, plan for 35 amps draw at 6 volts for 120 watts
output.
Advantages:
 Inexpensive, high current
DC/DC converter stabilizes voltage in automotive applications.
Also can be used to
provide regulated 12 volts from a 6 volt sealed lead acid battery--excellent
for special purpose UPS DC battery backups.
