I. Introduction
Thank you for purchasing this JCAT product. OPTIMO DIY
POWER SUPPLY MODULE is a linear power supply module
designed to work with mains transformer to provide regulated
low noise DC output. It is designed for use by skilled technician,
with right set of skills and tools. Make sure to read this user
manual prior to connection and use of the product.
Though you should get great performance out of the box, the
unit will break in and typically sound best after 100 to 150
hours of operation.

devices, in particular regarding the class of protection,
degree of protection must be strictly observed. Violating
safety requirement might led to electrocution or fire.
▪Make sure to provide sufficient ventilation for the power
supply module.
▪Keep the power supply module in a dry environment
away from humidity.
▪The power supply module is not intended for outdoor
usage.
▪The power module should not be discarded as unsorted
waste but must be sent to separate collection facilities for
recovery and recycling.
▪Keep the manual for future use of the product. The
manual is also available to download as a PDF file from

V. Connections
Optimo module has following connections:
1. AC input connectors (AC1, AC2) for connecting power
transformer.
2. DC output (GND (-), VCC (+)), regulated DC output.
3. Power ON LED indicator connector (2.54mm locking
connector.
Make sure to connect AC input to AC input connectors.
Connecting AC voltage to DC output will destroy module !!!
VI. Power Module Installation
1. Mount module to a stable surface using mounting posts,
module mounting holes are designed for M3 screws, and
arranged in 105 × 43 mm rectangular pattern. Protect it from
foreign objects.
2. Provide enough ventilation. As a rule of thumb ventilation
holes in enclosure should be located around heatsinks
attached to components on Optimo DIY module.

3. Module is designed to work with AC power transformer.
Recommended secondary side voltages under load for typical
module output voltages are listed below:
DC Output
Recomended

5V
5.5 V
7V
6.5V
9V
8.5V
12V
11V
15V
14V
Using lower voltage transformer will result in unstable DC
output voltage. Higher voltage should be avoided as additional
heat will be dispatched, which can result in module thermal
shutdown and will shorten it’s lifespan. Remember that
transformer voltage depends on many factors, and varies with
load, mains voltage and many other factors. With perfectly
matched transformer voltage the unregulated DC voltage in
module, that can be measured on leads of electrolytic filter
capacitors, at 3A load should be 1V higher than module output
voltage.
Minimum transformer power is calculated using following
formula: S=4,7×UTr, where UTr is nominal output voltage of the
transformer, so for 5V module and recommended 5.5V
transformer voltage, the minimal transformer power should
be 25,85VA. We do not recommend to use smaller

transformer, if so additional fuse matching max transformer
current had to be used
4. Solder transformer leads and DC output wires to Optimo
board. Use lead free solder. Maximum recommended
temperature for soldering is 340C. Due to high thermal mass
of PCB we recommend to use at least 50W soldering iron. Do
not use higher temperature, it might damage the PCB and
create poor solder joint. If your iron is not able to provide
enough heat setting higher temperature will only make things
worse. Double check all connections and mount of the module
before turning it on. All modules are factory tested and are
expected to work without any issues.
VII. Troubleshooting
If the power supply unit fails to function properly, please go
through the below checklist:
1. Check to make sure the AC power cord is properly connected
to the AC source and the power supply unit.
2. Check to make sure the AC source is On.
3. Check and all connections.
4. If you are still experiencing difficulties to get the power
supply unit to function properly, please visit www.jcat.eu for
further technical support instructions or contact us via email
at [email protected]
