The ALD-HPULN PS is the Dual Rail power supply, that can be used in three modi:
- Both rails can be used separately, i.e. for power two devices.
- Setting a jumper, both rails become a dual polarity / symmetric (+-) power supply.
- Double the output voltage to +30V / 2,5A
I.e. for supply Buffers, OPA's, AD/DA-converter, preamplifiers, active crossovers and other devices with a need of a symmetric / balanced voltage.
The new version also benefits of "Low Noise capacitors" and of an improved design.
The ALD-HPULN has a snubber option, which makes it possible to significantly reduce transformer ringing for both rails. 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 ALD-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 comparing to the smaller HPULN-versions
The scope of application is a main power supply for any kind of sensible devices with a need of up to 2,5 ampere per rail, i.e.:
- Audio interfaces
- Small amplifiers
- Audio Computers
As usual this power supply comes fully assembled and tested for seamless working.
