The PSU-4448 is a dual voltage rail, fully regulated, adjustable and low noise power supply KIT suitable for pro audio DIY projects.
It's low-profile and space saving design makes this perfect for use in 1u rack mount cases.
Each voltage rail is capable of 1.5Amps (when used with an appropriate sized power transformer that can supply the said current requirements.)
High quality double-sided, plated through PC board and components are used. On-board LED indicator lamp for a quick visual reminder when the board is powered up.
I've been selling this PSU model since 2008 on my FiveFishAudio website. I originally designed this to power my DIY project, racking Yamaha PM-1000 console preamp strips (that require 44Volts and +48Volts for phantom power). A lot of users have since bought this power supply kit to power their own Yamaha PM-1000 console preamp strip projects.
You need a suitable 18+18VAC power transformer to supply AC power to this power supply. I also sell these power transformers (30VA, 18+18, dual primary, dual secondaries, 110V-220V operation) on my website if interested, or you can source your own.
