These supplies have over load, over voltage, over temperature, and short circuit protection. SPECIFICATIONS: PSAK650 Series All specifications are based on 25°C, Nominal Input Voltage, and Maximum Output Current unless otherwise noted. We reserve the right to change specifications based on technological advances.

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. When in parallel connection only one unit might operate if the total output load is less than 5% of rated load condition. 5. 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. Due to advances in technology, specifications are subject to change without notice.
