SAFETY CONSIDERATIONS
GENERAL
This assembly guide must be reviewed for familiarization
with safety markings and instructions before assembly of
the power supply kit.
BEFORE APPLYING POWER
Verify that all components and parts are inserted in
the right location and correct orientation. Verify that
the power transformer wiring is congured correctly to
match the available AC line voltage in your country, i.e.
wired correctly for either 110Volt or 220Volt operation.
SAFETY EARTH GROUND
An uninterruptible safety earth ground must be provided
from the AC power source to your power transformer.
The WARNING sign denotes a hazard. Pay attention
to the procedure, instructions, or the like, which if not
correctly performed could result in damage to your
equipment, electronic component or personal injury.
Any interruption or disconnection, or lack of connection of
the protective earth terminal/safety ground may cause a
potential electric shock hazard that could result in personal
injury. (Grounding one conductor of a two conductor outlet
is not sufcient protection). Connect the safety ground of
your AC wall outlet to the metal case of your power supply
enclosure.
Some voltage adjustments described in this assembly
guide require power to be applied to the power supply
unit.
Capacitors on the power supply board may still be charged
even if the unit has been disconnected completely from it’s
source of power, i.e. unplugged from the wall, or switched
off.
Properly drain the capacitor charge using a bleed resistor
of sufcient power wattage and measure with a voltmeter/
multimeter to verify that no high voltages are present after
disconnection from the main power source.
For continued protection against re hazard, replace the
fuse(s) with proper rating applicable for your chosen
power transformer VA rating. Do not use repaired fuses
or short-circuit the fuseholder with a wire to bypass the
fuse.

GENERAL INFORMATION
1. DESCRIPTION
PSU-2448Plus+ Power Supply Kit is a four (4) rail power supply system designed to output a regulated and adjustable (+)
positive, (-) negative, +48Volt, and an extra (+) xed voltage output rail. It has a low-prole footprint, designed specically to t
inside a 1u standard rack height.
The Printed Circuit Board is professionally manufactured, with double-sided copper layers, plated-through holes, solder mask,
and silkscreen labels.
This Power Supply is designed to work with the FiveFish SC-1, X-12 Mic Preamp Kits, or any third-party preamp or opamp-
based project requiring a dual split +/- power supply.
The three (3) voltage rails (V+, V-, +48V) are easily adjustable using onboard trimmers. The V+ and V- outputs can be adjusted
for +/-15, +/-16, +/-18, or +/-24V projects…. or any other voltage you need.
The +48Volt DC output, used for phantom powering, can be nely adjusted to give you exactly 48 Volts.
A fourth voltage output is also available for powering auxilliary circuits. It’s up to the end-user to select what voltage they want
for this auxilliary output. The fourth voltage output can output either +5V, +12V, +15V or +18V, depending on the specic voltage
regulator used for this section. (The only requirement is Vaux < V+ output.)
All voltage rails feature built-in current-limiting and short circuit protection provided by the 3-terminal regulator devices. The
V+, V- and +48V voltage rails are additionally protected by in-line fuses against any accidental power supply short-circuit or
overload/overcurrent condition.

A POWER TRANSFORMER IS REQUIRED FOR PROPER OPERATION
DO NOT CONNECT THE PSU-2448PLUS+ KIT DIRECTLY TO AC MAIN LINES
The instructions on this page are for the FiveFish Audio PWR-TRAFO kit. If you are using a different power transformer
brand or model/part#, please consult your power transformer’s manufacturer’s documentation.

2. TOOLS & EQUIPMENT REQUIRED
A few basic tools and equipment are required to assemble this kit. These basic tools are not supplied
with the kit.
2.1. Soldering Iron and Lead - We recommend a temperature adjustable soldering iron. DO NOT
USE A 100 WATT SOLDERING GUN. A small to medium-sized soldering tip is required to
solder the small parts. You may use lead-free or 60/40 lead-based solder.
2.2 Cutter - You will need a cutter to cut component leads and wires.
2.3. Solder Sucker Pump - If you need to desolder a component, you’ll need one.
2.4. Multitester - Used for measuring resistance, continuity, and voltages.
2.5. Magnier & Lamp - I recommend a clean and well-lighted space for your assembly area.
2.6. Other Tools (not required, but nice to have) - Component lead bender, vise, tweezers, wire
stripper.

3. ASSEMBLY GUIDE
3.1 Solder all resistors and diodes.
Insert diodes in the correct orientation. Align the white band of diode with silkscreen on the PCB.
GENERAL INSTRUCTIONS: Open zip bag, insert component into board, solder.
All components are labeled in their own zip bags. There may be multiple components stored in each zip bag, with
their quantity noted. The voltage regulator part numbers (LM317, LM337) are marked on the device. Make sure to
insert each regulator into it’s correct location.
TIP: Solder smallest/shortest components rst before the larger/taller components to make assembly work easier.

3.2 Solder all ceramic capacitors. These are the small yellow components.
3.3 Solder Bridge Rectiers.
The Bridge Rectiers may be damaged if you apply too much heat for a long period of time.

3.4 Solder the (3) Light Emitting Diodes (LED).
LEDs, like diodes, have polarity and must be inserted in the proper orientation. See additional
photos below for correct orientation.
Mount the LEDs as low as possible on the PCB so
it wouldn’t interfere when the fuses are installed.
