1 Welcome!
Thank you for purchasing your new PS410 power supply. Before
operating or installing the unit, please read this manual thoroughly and
retain it for future reference. Additional copies of this manual are
available upon request or from our website at http://www.rtzaudio.com.
All units are carefully packed to endure the rigors of shipping and
handling. However, please inspect all contents and packaging
immediately upon receipt. Please report any problems to us immediately.
In the event of damage, retain all shipping and packaging materials for
shipper damage claims inspection.
The PS410 is designed to deliver a lifetime of trouble free operation. If
you experience any problems or difficulties, please contact us directly.
Do not attempt to modify, alter or repair the unit yourself. Each unit has
been carefully tested and packed prior to shipment. Any unauthorized
modifications may destroy the unit or severely degrade performance and
void the warranty.
2 Overview
The PS410 is a liner mode power supply designed to power RTZ UX410
module racks and is API 500 Series voltage compatible delivering bipolar
+/-16V and +48V phantom power. Each PS410 power supply can power
up to three UX410 racks (thirty 500 modules @120mA each) and
delivers a maximum peak load current of 4.5A. Forced air cooling is
provided by a long-life low-noise DC fan for maximum cooling efficiency
when mounted in a rack.
The PS410 is road-rugged unit and was designed as a heavy duty
alternative to self-contained power supplies. This large linear supply is
particularly well suited for audio applications and delivers clean high
current DC regulated power to all racks. The enclosure is made from
heavy gauge aluminum that provides additional heat sinking and allows
secure mounting in racks.

3 Power and Safety Fuses
The PS410 is world-wide capable linear power supply, but requires
internal transformer strapping changes to select the various line voltage
configurations. All units ship from the factory with the default strapping
set for 115V AC operation. Please contact us direct if you need to order
or configure the unit for 230V or other AC mains voltages.
The front panel LED’s provide power and fuse status for the 16V and
48V power rails. All LED’s should light when power is applied to the unit.
Check the front panel DC fuses if any LED’s fail to light. Check the AC
mains fuse if all LED’s fail to light with power applied to the unit.
3.1 AC Mains Fuse
The AC mains fuse is mounted on the rear panel above the DIN power
entrance connector. Typically the PS410 is configured for 115V or 230V
operation and uses one of the fuse types listed in Table 1 based on the
line voltage and transformer strapping.

3.2 DC Branch Fuses
The front panel DC safety fuses provide branch circuit protection for all
UX410 racks connected the PS410 supply. The LED’s beside each fuse
indicate power status and will fail to light if a fuse is blown.

3.3 DC Power Supply Connector Wiring
The DC power cable to the PS410 requires a six pin XLR connector and
cable. Separate power and analog grounds are maintained all the way
through to unit and back to the power supply for maximum ground signal
noise suppression.
Noisy components like relays and LED Vu meters typically reside on the
“power ground” while critical audio circuits reside on the “analog ground”.
These grounds eventually meet at a central “star ground” within the
PS410 power supply to provide a central common ground while keeping
the analog and power grounds separate throughout the rack.

4 Installation and Connections
The PS410 is designed for standard 1U 19” rack mounting. Ideally, the
unit should be mounted where cool air flows around all sides of the unit.
Do not obstruct the flow of air on the sides or rear of the PS410; air must
be able to flow around the sides and rear of the unit at all times. Do not
place the unit near strong magnetic fields and noise sources such as
power amplifiers, power supplies, transformers, motors, florescent
lighting, computers, etc. Mount the power supply away from any audio
module racks or other audio gear to avoid magnetic field radiation from
the PS410’s large internal supply transformer.
The power supply MUST be properly grounded at the AC outlet
connector. Never bypass the third ground prong on the power plug as
this creates a serious hazard and potential electrical shock. The chassis
ground stud on the rear of the unit may be used to ground the chassis to
an electrical earth ground also. Consult a certified electrician if you are
unsure of proper grounding or any AC mains connections to the unit.
The internal fan is thermostatically controlled and the speed of the fan
increases as the temperature of the unit rises. The fan will run at lower
speeds with less fan noise under light load or temperature conditions.
However, the fun will run at higher speeds if the unit is under heavy load
or placed in a hot environment. The supply should always be placed in
as cool an area as possible with plenty of air flow available to avoid heat
problems.
