Frequently Asked Questions
Q: What input voltages are supported by the Franklin 1945 power supply?
A: The 5-wire input configuration provides four distinct AC input voltage ranges: 100, 120, 220, and 230-240 VAC.
Q: Does this power supply require external noise filtering?
A: No, the unit features inherently low conducted and radiated noise levels, naturally meeting FCC Class A and VDE 0871 Class A standards without the need for additional filtering.
Q: What are the grounding requirements during installation?
A: Because it is a Class 1 power supply, the chassis must be explicitly connected to earth ground at your final application point.
