Notes
1. Other voltages are available. Contact sales office for details.
2. Standard models have foldback mode current protection with a high peak load capacity. This peak can be taken for 500 µs max.
3. For optional U-channel versions without fan/cover, change SMQ prefix to SMU, and delete suffix ‘-C’ from model number. Requires forced air cooling at 18 CFM.
