New version of the DLS-HPULN Power Supply: With high quality foil caps (chosen for lowest leakage current, two in parallel for better ESR) to improve reference voltage, regulation precision and avoid piezo effect!
The DLS (DC-input, Large size, Single rail) is the "High Current" version of the HPULN (High Performance Ultra Low Noise) Power Supply delivering up to 5 ampere for power-hungry devices, the real benefit is the dramatically reduced noise through 10x LT3045 in parallel operation.
This current might not be necessary in your application, nonetheless this fact is worth this power supply to become our DC-powered recommendation.
The scope of application is a main power supply as a pre-regulator after an existing regulated or unregulated DC-source for any kind of devices with a need of up to 5 ampere, i.e.:
- Audio interfaces
- Small amplifiers
With a bigger heatsink compared to other HPULN modules, the DLS-HPULN is also capable to better dissipate heat from the regulators. The voltage of the DC-source should be chosen to generate a low voltage difference between input and output to keep heat low, in passive cooled setups with a good heat dissipation the module is able to dissipate max. 4W (less is better and recommended).
As usual this power supply comes fully assembled and tested for 24h to ensure seamless working. A helpful HowTo will be provided after a purchase.
