I/O Power Supply Assembly (T8060,T8062)

Structure

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.

Chassis

The power supply chassis houses a maximum of six power supply modules. It may be mounted in a 19-inch rack or flush mounted on a panel. Table 1 identifies the available types of chassis.

I/O Power Supply Assembly (T8060,T8062)

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:

Input power failure - Active low status output. Indicates when the

input voltage is below 85 VAC or 18 VDC. There is a separate signal for each input.

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°C. The temperature is sensed near the air inle the module.

High-temperature shutdown - Internal signal that will shut down the

t (bottom) of

switching regulator if module temperature is above 85 °C. The temperature is sensed near the air inlet (bottom) of the module.

Output overvoltage - Internal signal that will shut down the switching

regulatorif the output voltage exceeds +18 VDC or +28 VDC for 15 volt and 24 volt modules respectively. Over-voltage protection circuitry activation is a permanent error condition, requiri to return module to normal operation.

DC output fail - Active high status output indicates the DC output

ng manual intervention

voltage has gone out of regulation. The DC output fail threshold is

13.75 VDC and 21.75 VDC (±0.25 VDC) for the 15 and 24 volt module respectively.

Output current limiting - Internal signal limits output current in

excessive current demand situations.

RESET - Active high status signal that is generated a minimum of 10

of the following:

ms (AC input module) or 0.5 ms (DC input module) after a POWER FAIL signal. RESET remains asserted for 200 ms (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 monitoring the module fail signal

of a module by turning off each input independently while

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 act signals are open collector and require external pull-up resistors.

ive. All status

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 connect these signals to a Regent I/O chassis.

Front Panel Indicators

The front panel of each I/O power supply module contains the following indicators:

Page 6

I/O Power Supply Assembly (T8060,T8062)

· Input Power Voltage Indicator

Each green INPUT POWER indicator is lighted when the associated input (Input A, Input B) is above the lower input voltage threshold.

· Output Power Display

The 10-segment LED indicator bar displays the approximate output current level percentage (0 - 100%)

· Output Power Indicator

The DC Output indicator is lighted when the I/O p

ower supply module's DC output is within tolerance. Out-of-tolerance conditions, loss of input power or brown-out, and module failures turn off this indicator.

Mounting flanges can be attached to either the rear or the front of the chassis. This allows flush mounting the chassis to a panel or mounting in a 19-inch rack.

The input crossover patch is on the T8200 chassis only.

Backplane Versions and Module Keying

Connector placement on AC input modules and backplanes differ from DC modules and backplanes. This prohibits insertion of the wrong input module type into a backplane.

Module slots in a chassis can be individually keyed to only accept a module of an particular output voltage.

Configuration

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 gro 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.

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 spec under the will provide the following load units:

I/O Power Supply Assembly (T8060,T8062)

Calculating the number of load units in your system helps you to determine the number of I/O power supplies your system needs. For economic power distribution, and to avoid overloading individual power supply units, calculate power supply loa

ding when configuring systems.

Regent I/O Triplicated Power Distribution

A chassis can contain two sets of triple-redundant power supplies for Regent I/O. Each of the triple-redundant 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 pow

er 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.

No periodic maintenance or calibration is required for I/O power supply modules. There are no user-replaceable 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.
