Selection Guide
Use the following criteria to confirm SPW482-53 S1 is the correct module for your application:
- Step 1 — Identify your FCS model: Confirm you have an AFC30D or compatible FCS cabinet
- Step 2 — Check redundancy requirement: SPW482-53 S1 supports redundant pair; if single supply is sufficient, consider SPW481-53
- Step 3 — Verify input voltage: Confirm site supply is 100–240 V AC
- Step 4 — Check suffix revision: S1 vs S2 — confirm with your Yokogawa system documentation or contact Konmask
- Step 5 — Confirm quantity: Redundant systems require 2× SPW482-53 S1 per FCS cabinet
