Notes

1. Nominal input voltage 12, 24 or 48 VDC.

2. For optional 4:1 input range: 9-36 VDC: Add suffix ‘A’ to WT2xx model number,

20-72 VDC: Add suffix ‘A’ to WT3xx model number.

3. For 3000 VDC isolation add suffix ‘X’ to model number.

4. For UL1950 approval, add suffix ‘XU’ to model number. UL approved product

is only available with 3000 VDC isolation and option ‘X’ pinout.

5. ‘X’ or ‘XU’ versions are not available with optional 4:1 input range.

6. Input current is at nominal input voltage.
