Our range of DC power supplies, besides delivering excellent noise specs and safety, have taken the above points into consideration into our design. Some of our unique design aspects include:

• A two-stage voltage regulation design consisting of a very low noise, open-loop design discrete transistor class-A driver pre-regulator first stage and a close-loop feedback regulator second stage. The first stage filters the bulk of the noise and takes away the heat from the second stage voltage regulator. The two- stage regulation design as a "gate" to prevent the downstream noise from traversing back to the AC power mains. It eliminates all types of noise downstream to your equipment and prevents pollution upstream to the AC mains. We would like to call this method as the brawn and the brain method. The pre-regulation stage (the brawn) handles most of these issues and isolate the actual regulator stage (the brain) from these ill artefacts. Free of these influences, the actual voltage regulator will be able to perform optimally in terms of noise, slew rate and output impedance, under all rated load conditions.

• For the Elite balanced DC power supply, we further improved their performance with a Balanced design. With this design, there are no signal ground noise injection by rectifier diodes and elimination of ground loop problems. Also switching noise contributions from AC-DC rectification diodes are also reduced by half, compared to conventional design. The downside is the customised transformer will need to be doubled in size compared to a conventional design size to deliver the same power. The weight and size of the linear power supply will increase. We feel the benefits more than outweigh the issues involved.
