Features:
- Selectable 115/230 V AC input feeds the SP22.5 conversion stage for an SR12.3 subrack.
- Separate front connectors handle mains input, monitoring contacts, external backup, and reset wiring.
- Green and red indicators combine with accessible test sockets for checking the three output rails.
The 6DD1683-0CC5 occupies the power-supply role in an AC-fed SIMADYN D SR12.3 rack.
Its regulated outputs distribute 5 V and symmetrical 15 V supplies to the installed rack hardware.
Cabinet installation maintains the documented open-equipment boundary around the mains and backplane circuits.
The Siemens 6DD1683-0CC5 SIMADYN D SP22.5 Power Supply Unit may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
AC Input and Protective Connection
- Voltage selection: The input stage is set for either 115 V AC or 230 V AC operation.
- Mains range: The selected nominal input permits +10 percent and -15 percent variation.
- Terminal path: X1 carries phase, neutral, and protective earth on separate pins.
- Input protection: The SP22.5 uses the documented T4A H 250 V fuse at F601.
Status and Test Access
- Ready state: A green indicator reports normal supply operation.
- Fault state: The red indicator identifies a monitored supply fault.
- Voltage checks: Individual front sockets expose 5 V, +15 V, and -15 V measurements.
- Battery access: The front arrangement also includes the backup battery compartment.
Supervision and Reset Paths
- Rail supervision: The supply monitors undervoltage conditions on its regulated outputs.
- Relay reporting: X2 provides contacts for the power-supply and fan monitoring path.
- External backup: X3 accepts the documented external battery connection.
- Reset input: X4 provides the dedicated connection for the external reset signal.
Backplane Power Relationship
- Logic rail: The 5.1 V output supplies the principal digital board voltage.
- Positive rail: The +15 V output supports the rack hardware requiring a positive auxiliary supply.
- Negative rail: The -15 V output completes the symmetrical auxiliary supply pair.
- Installation boundary: The power unit and rack require a cabinet or restricted electrical area.
