Nominal input voltage 5, 12, 24 or 48 VDC.
For optional 4:1 input range: 9-36 VDC: Add suffix ‘A’ to WA2xx model number, 18-72 VDC: Add suffix ‘A’ to WA3xx model number.
For 3000 VDC isolation add suffix ‘X’ to model number.
For UL1950 approval, add suffix ‘XU’ to model number. UL approved product is only available with 3000 VDC isolation and option ‘X’ pinout.
‘X’ or ‘XU’ versions are not available with optional 4:1 input range.
Input current is at nominal input voltage.
