The SLS-HPULN PS is AC-powered* (including an ATR snubber) and offers a huge improvement on PSRR - 5x LT3045 followed by another 5x LT3045 in series, resulting in an Ultrahigh PSRR of 2x76dB at 1MHz.
The new version also benefits of "Low Noise capacitors" and of an improved design.
The SLS-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 In case it's ordered alone, the two film capacitors will be delivered unpublished, to measure your transformer and publish necessary parts (a resistor is necessary, it's resistance is to find out with Quasimodo).
The SLS-HPULN power supply can also be used without a snubber.
With a bigger heatsink mounted it is also capable to better dissipate heat from the regulators.
The scope of application is a main power supply for any kind of sensible devices with a need of up to 2,5 ampere, i.e.:
- Audio interfaces
- Small amplifiers
- Audio Computers
As usual this power supply comes fully assembled and tested for seamless working.
For more information regarding heat and transformator recommandation please note the instructions in FAQ.
*The SLS-HPULN PS can also be delivered as "DC-only" version. More info can be found in the FAQ.
