Notes
1. Other output voltages available. Contact sales.
2. Standard input is screw terminal. For optional IEC320 input and on/off switch, add suffix ‘-D’ to model number.
3. Standard output is screw terminal. For optional Molex output connector, add suffix ‘-G’ to model number.
4. For current share option, add suffix ‘-I’ to model number (remote sense not available). This option also adds internal block diodes.
5. For AC fail option, add suffix ‘-L’ to model number (single output only). UVLO function is disabled. Output is low when input is <80 VAC, high (5 V) if input is >86 VAC.
6. When ordering place option suffixes in alphabetical order, e.g. SMM400PS24-CDI.
