1. Description
The power supply assembly consists of a power supply chassis containing up to six power supply
modules. The chassis may be configured to distribute power in various combinations. For example, a
chassis containing six power supply modules may be set up with three modules providing triplicated
power for Regent+Plus I/O assemblies and three modules providing field power in a N+1 configuration.
Alternatively, the chassis may be set up to provide separate dual 24V dc supplies for both a Trusted
system and associated field devices.

Each primary power input is individually fused and filtered with both standard line filters and metal
oxide varistors (MOVs). The filters attenuate any high-frequency common mode and normal mode
noise present in the power distribution system. The MOVs clamp high-voltage transients.
Filter, rectifier, and power factor correction circuits convert primary ac input power to bulk dc voltage.
The switching regulator converts bulk dc power to regulated dc output voltage. Sensing, status, control
and timing circuits provide for the following:

• Bulk power failure - Active high status output on ac input modules only. Indicates the dc bulk
voltage (PFC output) is outside the specified range. There is a separate signal for each input.
• High-temperature warning alarm - Both an active high and active low status output are
provided. Indicates the module temperature exceeds 75
the air inlet (bottom) of the module.
• High-temperature shutdown - Internal signal that will shut down the switching regulator if
module temperature is above 85
the module.
• Output over-voltage - Internal signal that will shut down the switching regulator if the output
voltage exceeds +18

intervention to return module to normal operation.
• dc output fail - Active high status output indicates the dc output voltage has gone out of
regulation. The dc output fail threshold is 13.75

• Output current limiting - Internal signal limits output current in excessive current demand
situations.
• POWER FAIL - Active high status signal that indicates impending loss of output power due to
one of the following:
• - Both inputs have indicated power failure
• - Remote off control signal activated
• - Thermal shutdown
• - Output-over voltage
• RESET - Active high status signal that is generated a minimum of 10 ms (ac input module) or
0.5ms (dc input module) after a POWER FAIL signal. RESET remains asserted for 200ms
(minimum) after module power-up.
• PFC off - Active low input that turns off the power factor correction of an individual input. This
signal provides the capability to test the input circuitry of a module by turning off each input
independently while monitoring the module fail signal
• Remote off - Active low input that turns off the output power of a module.
Note: Bulk Power Fail, PFC Off and Remote Off are accessed through the monitor module connector
on the chassis backplane. The monitor module connector allows for a future development of a
monitor card that would provide remote control and enhanced monitoring of the power supply
chassis.
Active low signals are not maintained while RESET is active. All status signals are open collector and
require external pull-up resistors.
RESET is used in the Regent I/O transceivers for power system interlocking within the I/O system. A
power failure (either input power or module fault) activates RESET and turns off the dc output front
panel indicator.
The POWER FAIL and RESET signals are required for proper operation of Regent I/O transceivers
and I/O modules during power up, power down, and loss of power. Refer to Assembly Installation in
the associated Regent Product Description for details of connecting these signals to a Regent I/O
chassis.

1.4. Front Panel Indicators
he front panel of each I/O power supply module supports three LED indicators detailed in the
T
following sub-paragraphs
1.4.1. Input Power Voltage Indicator
Each green INPUT POWER indicator is lit when the associated input (Input A, Input B) is above the
lower input voltage threshold.
1.4.2. Output Power Display
The 10-segment LED indicator bar displays the approximate output current level percentage (0% 100%)
1.4.3. Output Power Indicator
The DC Output indicator is lit when the I/O power supply module's dc output is within tolerance. Out-oftolerance conditions, loss of input power or brown-out, and module failures turn off this indicator.

3. Configuration
3.1. Current Sharing
The modules are capable of current sharing by connecting their outputs together in parallel. This can
be done external to the chassis or by using a shorting bar that mounts directly to the output terminals
on the chassis backplane. This allows separate groups of modules from within a single chassis to have
their outputs configured as Single, Dual or N+1. The module uses a passive ‘droop’ method of current
sharing and will share to within 25% of the rated load.
3.2. REGENT Power Supply Load Units
When using the power supply system with Regent and Regent+Plus , power supply loading is based
on the number of I/O modules in the I/O chassis and the load imposed by each I/O module. Load units
for each I/O module are shown in that module’s product description and specification sheet under the
Safetybus Power heading. A set of three power supply modules will provide the following load units:
Available Load Units (for a set of three power supplies)
Number of I/O Units
(Chassis):
Load Unit Capacity:
Calculating the number of load units in the system helps determine the number of I/O power supplies
required by the system. For economic power distribution, and to avoid overloading individual power
supply units, calculate power supply loading when configuring systems.

3.3. Regent I/O Triplicated Power Distribution
A chassis can contain two sets of triple-redundant power supplies for Regent I/O. Each of the tripleredundant I/O power supply modules within the I/O power supply chassis provides power for one leg of
the three redundant legs of the I/O Safetybus transceivers, and provides power to all the I/O modules
within its associated I/O chassis. Each I/O module contains a diode OR power-sharing circuit that
receives power from all three I/O power supply modules.
Should any I/O power supply module fail, only one leg of the transceiver modules loses power: the two
remaining legs maintain proper Regent operation. In addition, all the I/O modules continue to operate
properly by drawing their current from the two remaining power supplies within the I/O power supply
assembly.
I/O transceivers and I/O modules require power fail and reset status signals for proper operation.

4. Maintenance
No periodic maintenance or calibration is required for I/O power supply modules. There are no userreplaceable parts.
A failed I/O power supply module can be hot-replaced without disrupting system operations. Main
power wiring and I/O power cables (connected to the chassis) are not disturbed during module
replacement.
