SMM400PDXX: 10% minimum load is required for all outputs to maintain the ripple and regulation. Outputs are fully isolated. 2. For cover version add C to the model number 3. Standard output is screw terminal. For optional Molex output connector, add suffix -G to model number, OEM quantities, contact Sales. 4. 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, OEM quantities, contact Sales. 5. For current share option, add suffix -I to model number (remote sense not available). This option also adds internal blocking diodes, OEM quantities, contact Sales. 6. For U-Channel with optional solid cover, add suffix -A to the model number (external dimensions remain the same). 7. Standard input for U-Channel version is screw terminal. For optional IEC320 input, on/off switch and cover add suffix -D to model number. 8. Available for OEM quantities, contact Sales. 9. When ordering place option suffixes in alphabetical order, e.g. SMM400PS24-GI.
