ABB DSSS 171 3BSE005003R1 Power Voting Unit

The DSSS 171 is a Power Voting Unit, manufactured and designed by ABB as part of the S100 I/O Series used in the Advant OCS with Master Control System. Our team is available 24/7 to support you with your urgent needs for critical spare parts, please contact us.



 

DSSS 171 3BSE005003R1 Power Voting Unit

 

The DSSS 171 power voting unit is used for connecting dual DC 24V (24V_A, 24V_B) supply to a single 24V power bus. The voltage regulator unit DSSR 170 converts 24 V d.c. to 5 V d.c. voltage.

 

DSSS 171 is housed in a heatsink case permitting natural or forced air coolant. If the subrack is powered from a single DC 24V network, the DSSS 171 can be omitted. The DSSS 171 contains the 24V power circuits and a supervisory logic circuitry indicating and signalling status for the power supply circuits 24V_A, 24V_B, also indicating a blown fuse for the common voltage output to the subrack PBC - bus.

 

On the DSSS 171, supervisory logic circuitry is powered from the 24V_C bus (24V_CA), a 24VS terminal making the 24V inlet/outlet for redundant powering the logics of compatible DSSS units within a system as required.

 

Supervisory Logic is watching 24V_A and 24V_B voltage levels. The LEDs A and B at the DSSS 171 front panel will indicate:

 

LIVE / green = Voltage above min. level

FAIL / red = Voltage below min. level.

 

The output signals LIVE24_A/B and FAIL24_A/B are sent synchronously with the corresponding LED indications. The red panel LED, PBC FAIL, will light for a voltage black-out at the PBC - bus in the sub rack. Where the 24VS is not connected, PBC FAIL means a blown fuse F524 in the DSBB 188. (Where the 24VS is connected for redundant supervisory power supply PBC FAIL can also indicate a low voltage at the 24V_A and 24V_B terminals; thus, the LEDs A FAIL and B FAIL will light together with the PBC FAIL LED.) Key data for the power voting unit DSSS 171 and the power bus plane DSBB 188 is presented in the table below.
