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.
5. For output currents >50 A, please utilise remote sense to meet regulation ratings.
6. Available for OEM quantities, contact Sales.

Options
For U-channel version replace ‘SMC’ in the part number with ‘SMD’ and remove ‘-C’ e.g. SMD600PS12 (See Derating Curve Note 1.)
Constant current limit (95-100%) add suffix ‘-B’ (not available on 3.3 V or 5.0 V models), OEM quantities contact Sales.
Current share and internal ORing diode add suffix ‘-I’ to model number, remote sense not available on ‘-I’ models, OEM quantities con-
tact Sales.
Optional IEC320 inlet replace suffix ‘-C’ with ‘-D’. Not available for SMD models.
