Why would I use a non-regulated power supply for Ultra SlimPaks or the DC Action IQ?
The Ultra SlimPaks and the DC Action IQ are powered from 9-30 Vdc (Except the bridge input models Q448, Q446, G448 and WV448 which are 18-30 Vdc). They all regulate the power internally and do not require a regulated power supply. One nice feature of an unregulated power supply is the ability to provide extra current in case it should be needed for whatever reason, usually a fault condition of some kind. Let’s say we have a 13 A, 24 Vdc unregulated power supply. The power supply will provide more than 13 A. When the current demand increases the voltage level decreases. The Action Instruments’ products will continue to operate down to 9 Vdc!
