2.1 OPR200-24S / OPR200-24R Description:
The Models OPR200-24S and OPR200-24R are 1U rack mountable power supplies designed to
operate in single and redundant power configurations respectively. OPR200-24S has one built-in
universal AC to 24V DC power supply, and OPR200-24R has two built-in universal AC to 24V
DC power supplies with two IEC AC plugs for complete redundancy. OPR200-24S provides up
to 200W of power, and OPR200-24R provides up to 400W of redundant power*to the system
that each is attached. Each model has its own AC-INLET (one for OPR200-24S and two for
OPR200-24R for redundancy), ON/OFF switches, and power LEDs (one for OPR200-24S and
two for OPR200-24R). Both models have two built-in alarm circuits with red LEDs for low DC
power monitoring and for remote power management. In addition, models OPR200-24S and
OPR200-24R have Logic Interface for power supply alarm circuits.

Alarm Systems
4.1 Alarm Monitoring System
The Models OPR200-24S and OPR200-24R 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 20VDC.
OPR200-24S Alarm Indications
If for some reason the voltages in power supply Model OPR200-24S 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 3
(Power Supply Alarm)
Logic Low = 0 Logic High = 1
Pin 16
(Power Supply Alarm)
Logic High = 1 Logic Low = 0
OPR200-24R Alarm Indications
If for some reason the voltages of power supply 1 in the Model OPR200-24R 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.
DB25 Pin Out Normal Condition Power Supply Failure
Pin 3
(Power Supply 1 Alarm)
Logic Low = 0 Logic High = 1
Pin 16
(Power Supply 1 Alarm)
Logic High = 1 Logic Low = 0
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.
DB25 Pin Out Normal Condition Power Supply Failure
Pin 17
(Power Supply 2 Alarm)
Logic Low = 0 Logic High = 1
Pin 9
(Power Supply 2 Alarm)
Logic High = 1 Logic Low = 0

Installation and Maintenance
5.1 Installation
OPR200-24S and OPR200-24R may be installed in 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 24V DC power) with the DC output connector located at the rear of the OPR unit.
¾Next, ensure that the front panel power switch(es) are in “OFF” position.
¾Connect the AC power cord to the unit by plugging the free end of the power cord into a
standard three prong AC outlet.
¾Ensure 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.
OPR200-24S 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.
OPR200-24R 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.
