Application Information
1. Standard product is open frame with negative logic.
2. Baseplate versions are built to order.
3. Please add one of the following suffix codes to the part number when ordering:
AL = Open Frame/Negative logic, AH = Open Frame/Positive Logic, BL = Baseplate/Negative logic, BH = Baseplate/Postive logic.
4. For input reverse voltage protection, use a parallel diode across the input terminals preceded by a 5 A fuse.
5. Typical value measured at full load and nominal 48 V input.
