The Models OPR200-05S and OPR200-05R are 1U rack mountable power supplies designed to
operate in single and redundant power configurations respectively. OPR200-05S has one built-in
universal AC to 5V DC power supply, and OPR200-05R has two built-in universal AC to 5V DC
power supplies with two IEC AC plugs for complete redundancy. OPR200-05S provides up to
200W of power, and OPR200-05R provides up to 400W of redundant power* to the system that
each is attached. Each model has its own AC-INLET (one for OPR200-05S and two for
OPR200-05R for redundancy), ON/OFF switches, and power LEDs (one for OPR200-05S and
two for OPR200-05R). Both models have two built-in alarm circuits with red LEDs for low DC
power monitoring and for remote power management. In addition, models OPR200-05S and
OPR200-05R have Logic Interface for power supply alarm circuit.

Alarm Systems
4.1 Alarm Monitoring System
The Models OPR200-05S and OPR200-05R have the ability to monitor output DC voltage, and
trigger an alarm when the output DC voltage starts to decrease below the threshold limit. The
power supply models have a threshold limit of 4V DC.
OPR200-05S Alarm Indications
If for some reason the voltages in power supply Model OPR200-05S drop below the threshold
limit (due to overload, for example) the DB25 interface pin 16 will go logic LOW, and pin 3 will
have logic HIGH indicating power supply failure.
DB25 Pin Out Normal Condition Power Supply Failure
Pin 16
(Power Supply Alarm)
Pin 3

OPR200-05R Alarm Indications
If for some reason the voltages of power supply 1 in the Model OPR200-05R drop below the
threshold limit (due to overload, for example) the DB25 interface pins 3 will go logic HIGH, and
pin 16 will have logic LOW indicating power supply 1 failure.

Furthermore, if the voltages of power supply 2 drop below the threshold limit. The interface pin
17 will go logic HIGH, and pin 9 will have logic LOW indicating power supply 2 failure.

Installation and Maintenance
5.1 Installation
OPR200-05S and OPR200-05R may be installed in a fixed, semi-fixed and mobile environments
that meet the environmental characteristics specified in Chapter 2. These models are designed to
be mounted in a standard 19” equipment rack utilizing the mounting holes provided on the front
of each unit. It is recommended that at least 1 rack unit (1U = 1.75”) gap be provided above
or below the OPR power supply unit for proper air flow.
Once these power supplies are mounted in the rack, they should be connected to the system (that
only requires 5V DC power) with the DC output connector located at the rear of the OPR unit.
OPR200-05S Setup
Once all the wires are connected properly as described in the above installation paragraph:
(1) Turn "ON" the front panel switch.
(2) The "Power" LEDs, should light up.
Now the system is ready to operate to its required purpose.
OPR200-05R Setup
Once all the wires are connected properly as described in the above installation paragraph:
(1) Turn "ON" the front panel switch for Power supply 1
The "Power 1" green LED, and "PS 2 Alarm" red LED should light up. Indicating Power
supply 1 is "ON" and Power supply 2 is "OFF"
(2) Turn "ON" the front panel switch for Power supply 2
This should clear the "PS 2 Alarm" red LED and cause the "Power 2" green LED to illuminate.
Now the system is ready to operate to its required purpose.
WARNING: Observe polarity when making connection to the rear of model
OPR200-05S / OPR200-05
¾ Next, ensure that the front panel power switch(es) are in “OFF” position.
¾ Connect the AC power cord to the unit by plugging the free end of the power cord into a
standard three prong AC outlet.
¾ Ensure that the AC power plug(s) located at the rear end of the power supply are
connected to a clean and well-grounded Universal AC source.

Monitoring AC Input and DC Output
OPR Series models have switches that monitor AC current input and DC current output.
Whenever the “Power” switches are “ON”, the LEDs embedded in the switch should light up.
These indicate good AC input. Similarly the “Power 1” (or “Power1” and “Power2” in redundant
models) LEDs should turn green, indicating good DC output.
Alarm Conditions for Redundant Power Supply
• Power 1 Failure
• AC plug disconnected to Power 1
• Front panel Switch to Power 1 is in “OFF” position
• Power 2 Failure
• AC Plug disconnected to Power 2
• Front panel Switch to Power 2 is in “OFF” position
5.2 Maintenance
The Models OPR200-05S and OPR200-05R should be treated with the sufficient care.
• Do not use abrasives or solvents, as they may mar surfaces
• Do not subject the unit to excessive temperature extremes
• Do not subject the unit to excessive moisture or spilled liquids
• Do not subject the unit to sudden or severe shocks
• Never operate the Model OPR200-05S / OPR200-05R with any of the covers removed
5.3 Warnings
To reduce the risk of fire, electric shock or product damage, DO NOT expose the OPR200-05S /
OPR200-05R unit(s) to direct heat, rain, moisture, dripping or splashing. DO NOT place any
object filled with any kinds of liquids on the unit(s). To prevent damage to LEDs and switches,
DO NOT place the front panel of the unit face down, and/or DO NOT press against the front
panel.
Optimal Power is not responsible for any kinds of damages sustained through the use of
this product.
