The SD-HPULN PS is a tiny Dual Rail power supply, which is able to work in two modi:


- Both rails can be used and adjusted between 0-15V completely independent, i.e. to supply two devices with a small power need

- Connecting both sides with a jumper, both rails become a dual polarity / symmetric power supply.


I.e. for use with Buffers, OPA's, AD/DA-converter and other devices with a need of a very low power symmetric power supply.

Without a rectifier onboard (powered by your DC-source) this tiny power supply is designed to be mounted into small enclosures and devices, while replacing the stock reg's.

It shall be mentioned again, that due to the low heat dissipating capability this device should be used to supply low power devices only and to care about a low input-to-output-voltage-difference and an adequate cooling (see FAQ for more information).


As usual the SD-HPULN power supply comes fully assembled and tested for seamless working.
