The AWS-HPULN PS (AC-powered, Wall-mount, Single Rail) is designed to supply up to 6A with the quality and precision of the state-of-the-art LT3045 regulator.
The module is mounted permanently on a 3mm aluminium bar (isolated), to be mounted on a heatsink with thermal grease with its whole surface for optimal heat dissipation. This also solves the challenge of heat dissipation using "on board heatsinks", which are limited due to the small dimensions of the PCB.
That also reduces the need of keeping Vdifference to a low level, possible headroom usually depends on the used heatsink dimension.
 
The AC connector offers four inputs, so that two secondary windings can be connected, without limiting wire gauge. Ten black M3 screws with wishers are included, drilling holes into the heatsink must be done precisely to match 3,6mm holes.
 
The new version also benefits of "Low Noise capacitors", an LC filter (28.200uF in total ) in the input and of an improved layout. The scope of application is a main power supply for any kind of sensitive devices with a need of up to 6 ampere, i.e.:
- Audio interfaces
- DAC's- Small amplifiers
- Audio Computers
 
Anti-transformer-ringing snubber
The AWS-HPULN has a snubber option, which makes it possible to significantly reduce transformer ringing. Please see "Quasimodo PCB" for more information. In case of ordering this power supply with a transformer, the snubber will already be configured. In case it's ordered alone, the snubber can be set by the customer - we recommend to use the Quasimodo jig for that purpose.
The AWS-HPULN power supply can also be used without a snubber.
 
As usual this power supply comes fully assembled and tested for seamless working. The module will be shipped without a heatsink - the picture is an example only.
