Power Supply Function
The DS3820PSCC converts the incoming DC supply into a +28 VDC output for the equipment it is designed to power. The specified input range allows operation across a range of DC supply conditions around the nominal 125 VDC input.
The output voltage is the key electrical interface to verify when identifying this assembly for maintenance or replacement. Input voltage compatibility alone does not establish that another power supply assembly is interchangeable.
Identification and Output Configuration
The DS3820PSCC is identified as a Mark IV DC power supply assembly with an 80-140 VDC input and a P28V output configuration. It is distinct from other Mark IV power supply assemblies designed for different DC output rails.
Its +28 VDC output must match the voltage requirement of the connected equipment. The available specifications do not establish the rated output current, total power capacity, voltage regulation tolerance, or ripple level, so these values should not be assumed when assessing load capacity.
Replacement and Configuration Checks
Before selecting a replacement, verify the complete part number against the installed assembly and Mark IV system documentation. Check the DC input range, required +28 VDC output, physical mounting arrangement, and electrical connections.
Do not assume that another Mark IV power supply assembly is interchangeable solely because it has the same input voltage range. Different assemblies may provide different output voltage configurations.
Frequently Asked Questions
Q: What is the nominal input voltage of the DS3820PSCC?
A: Its nominal input voltage is 125 VDC. The specified operating input range is 80 to 140 VDC.
Q: What is the difference between DS3820PSCC and DS3820PSCB?
A: The DS3820PSCC provides a +28 VDC output, while the DS3820PSCB is identified as a Mark IV power supply assembly with +5 V and +/-15 V outputs. They have different output configurations and should not be treated as interchangeable.
Q: Can the output load capacity be determined from the available specifications?
A: No. The output current and rated power are not established by the available data. Check the applicable GE technical documentation before calculating the permissible connected load.
