Introduction
The PWS1005W power supply provides up to 1000 watts of precision power to a 12, 24, 32, 36,
48, or 72 (Rail) VDC electrical system from a 110 or 220 VAC source.
Designed for service in the most unforgiving environments, the PWS1005W has an operational
temperature range spanning -40°C to +55°C. The unit’s rugged chassis is built to be water and dust
resistant to meet the IP66 rating, while internal components are sealed with additional RTV silicone
for maximum vibration and shock protection.
Internally, the recently updated single board design incorporates time-tested switch-mode
technology for unmatched efciency and ultra-quiet operation. New circuit innovations reduce
output ripple to levels previously only available from bulky, inefcient linear power supplies. In
addition, multiple stages of ltering on the input and output reduce radiated and conducted noise
to very low levels.
Built for the safest operation possible, reliability features built into the PWS1005W include
an input fuse, thermal shutdown, under voltage shutdown, and short circuit shutdown, all
with automatic recovery. Devices connected to the power supply are protected by an output
over voltage crowbar circuit and output current limiting. All these alarm states and the unit’s
operating condition are easily monitored on the bright and easy-to-read LED Indicator display.
The box you have received should contain the following:
• One PWS1005W
• This User Guide
• One Warranty Card
If anything is missing or damaged please contact your dealer or Analytic Systems for a replacement.

installed and connected to the power source and load. See Installation for more details.
TO TURN THE UNIT ON:
1. Move the Power Switch to the ON position.
2. The alarm buzzer will sound briey and the POWER LED will begin glowing green
indicating the power supply is supplying the load.
TO TURN THE UNIT OFF:
1. Move the Power Switch to the OFF position and wait for the POWER LED to stop
glowing.
2. Once all the LEDs are off, it is safe to disconnect the load and power source from the
power supply.
3. Move the Power Switch back to the ON position while disconnected from the power
source to discharge the internal capacitors.
4. After 30 seconds, move the Power Switch back to the OFF position. The unit can now be
safely serviced or put into storage.

MOUNTING
Mount the unit in a WELL VENTILATED location. Allow at
least 1 inch (2.54 cm) of clearance surrounding the unit
for adequate cooling.
The PWS1005W is designed to meet IP66 rating,and is
resistant to water spray from any direction. These units
can be mounted in wet locations but are not suitable for
submersion.
WARNING: TO PREVENT THE RISK OF ELECTRIC SHOCK, NEVER DISCONNECT THE
INPUT OR OUTPUT WHILE THE UNIT IS ENERGIZED.
Installation
DC OUTPUT CONNECTION
This unit is equipped with two 8AWG TEW-type stranded leads terminating bare copper. The
wiring for this connection can be found on the units front panel label and is as follows:
Wire color Polarity
Black AC Live/Hot
Gray AC Neutral
Green/Yellow AC Ground
Wire color Polarity
Black DC Output Negative
Red DC Output Positive
This unit’s maximum continuous output current is 40A. When connecting devices to the power
supply, ensure total connected load is less than 40A and that the wiring used is rated for this
current.
*This unit shown with the Portable Option
AC INPUT CONNECTION
This unit is equipped with a 3.05m/10.00ft 3x14AWG power cord ending in a NEMA 5-15
compatible plug suitable for connection to any typical North American AC Mains outlet. If
you need to hard-wire this connection, cut the plug off the cord and strip the wires inside, the
wiring for this cord as follows:
CAUTION: DO NOT CONNECT THE LOAD IN THE REVERSE POLARITY!!
This will activate the reverse connection protection which will blow the output fuses inside the unit
in order to protect the device.The unit will be inoperable until these fuses have been replaced.

98
Output Fuse Replacement
The power supply is protected from damage by reverse polarity connection by output fuses. If
the load is connected to the unit in the wrong polarity, the output fuse(s) will blow to protect
the power supply.
Afterwards, the fuses must be replaced for normal unit operation. See the specications
section for rating and make fuses. All the output fuses must be replaced as they operate in
parallel to add up to the full output current capability of the power supply.
CAUTION: BEFORE REPLACING THE FUSES, DISCONNECT OR TURN OFF THE AC
POWER TO THE POWER SUPPLY AND DISCONNECT IT FROM THE LOAD.
When connecting the load to the unit a small arc can form between the connectors. To ensure
spark-free connections, make connections only when the power switch is OFF.
TO REPLACE THE FUSES
1. Loosen and remove the ten (10) screws holding the front panel to the unit chassis.
2. Gently wiggle the front panel to unplug it from the main circuit board. The output fuses
are mounted in fuse holders close to the output cable or connector.
3. Remove and replace them all with the same style and current rating.
4. Gently push the front panel connector back onto the main circuit board, ensuring that any
O-Ring or gasket remains properly seated. This is particularly important for W and Y models to
ensure a water-tight seal!
5. Carefully re-insert all the front panel screws loosely, making sure non are cross threaded.
Once all screws are started, tighten them in sequence. These screws are made from corrosion
resistant stainless steel and are softer that regular steel screws, so take care to not over-
tighten.
6. Reconnect AC power to the unit and ensure that it turns ON. Carefully recheck the
polarity of the output connections and then reconnect the load to the power supply. Normal
operation should resume immediately.

This unit is tted with 5 LED indicators and an alarm buzzer to display and diagnose any
malfunctions. In the event of a malfunction, the unit will sound the buzzer to alert you before
shutting itself down. You should then immediately check which LEDs are glowing to determine
the cause of the alarm.
LED Indicator Meaning
OVERTEMP The power supply’s internal temperature is too high for safe operation.
Fix: The power supply will shut down until it cools sufciently. If this happens
repeatedly, you may need to remount the power supply for better ventilation
and cooling.
Disconnecting some connected devices to reduce the load on the power supply
may also help.
OVERLOAD The load is drawing too much current from the power supply.
Fix: The unit is operating above its peak output current for too long of a time.
Disconnect some of the connected devices to reduce the load on the power
supply. Check that the combined load of each device connected to the power
supply does not exceed the unit’s continuous output current. See Specications
for more details.
UNDER V. INPUT The AC input voltage is too low for proper operation.
Fix: Check that the AC power source is a proper voltage rating for the power supply.
Check that the input wiring and connectors are free of damage and corrosion.
If all the above is in proper working order, the cause is likely an internal
component failure and the unit must be returned to an authorized service
center for repair.
UNDER V. OUTPUT The power supply’s output voltage is too low for proper operation.
Fix: The output current may be exceeding the unit’s maximum rating causing the
output voltage to drop to maintain the current at that level. Check that the
current is not excessive and the OVERLOAD LED isn’t glowing. If it is, reduce the
load on the power supply.
Check that the output wiring and connectors are free of damage and corrosion.
If all the above is in proper working order, the cause is likely an internal
component failure and the unit must be returned to an authorized service center
for repair.
