DESCRIPTION
The PSAK150 series of AC/DC switching power supplies provides 150 Watts of continuous output power in an enclosed design. All models
have a single output and a universal input range. Some features include efficiency up to 89%, 0.98 typical power factor, active PFC, and
< 0.5W no load power consumption. These supplies are Energy Star compliant and have brown-out, over load, over voltage, over
temperature, and short circuit protection. All models are 100% full load burn-in tested.

NOTES
1. Ripple & noise is measured at 20MHz bandwidth by using a 12" twisted pair-wire terminated with a 0.1µF capacitor and a
47µF capacitor in parallel.
2. Tolerances include set up tolerance, line regulation, and load regulation.
3. Derating may be needed under low input voltages. Please check the derating curve for more details.
4. The power supply is considered a component, which will be installed into final equipment. The final equipment must be reconfirmed that it still meets EMC directives.
5. When in parallel operation only one unit might operate if the total output load is less than 5% of the rated load condition.
