Frequently Asked Questions
When should I use DC power supply vs AC?
DC (PD022): when your panel already has 24VDC distribution, for battery backup systems, mobile equipment. AC (PA202): direct connection to mains power. Choose based on available power source.
What's the advantage of DC input?
DC input: no inrush current, higher efficiency (85% vs 75%), reverse polarity protection, compatible with battery/UPS backup. Preferred for critical applications.
How many I/O units can PD022 support?
Same as PA202: approximately 20-30 I/O units (5A at 5VDC). Calculate total 5VDC consumption of all units before sizing.
Do I need fuse on 24VDC input?
Yes, external fuse recommended: 10A slow-blow for PD022. Protects wiring and supply from short circuits. Install close to power supply input.
