Notes
1. This peak can be taken for 500 µs only, average power should not exceed the maximum power.
2. Ripple & Noise is measured using 0.1 µF ceramic and 22 µF electrolytic capacitor, 20 MHz bandwidth.
3. Alternative output voltages available. Consult sales.
4. Load regulation increases to 2% for 0-100% load change.

Options
• Current share and internal oring diode add suffix ‘-I’ to model number. Note that this option includes output blocking diodes.
Remote sense is not available with current share.
• Optional IEC320 inlet add suffix‘-D’ to model number.
• Optional Molex output connector add suffix ‘-E’ to model number.
• For U-Channel version replace ‘SMR’ in the model number with ‘SMS’ e.g. SMS800PS12 (note that 25 CFM cooling air is required).
Dimensions are 8.00(l) x 4.33(w) x 2.56(h) (203.2 x 110.0 x 65.0).
• For top mounting fan version replace ‘SMR’ in the model number with ‘SMT’ e;g; SMT800PS12.
Dimensions are 8.00(l) x 4.33(w) x 3.40(h) (203.2 x 110.0 x 86.4).
• For multiple option codes place codes in alphabetical order. e.g. SMR800PS12-DI.
