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. Available from Farnell. See pages 204-206.
