T+A Elektroakustik PS 3000 HV Power Supply for A 3000 HV / PA 3100 HV

A massive upgrade with 240,000µF reserve capacity that powers the output stages, allowing the stock supply to power the small-signal circuits.

This external PSU connects to the A 3000 HV power amp or the PA 3100 HV integrated amp and powers the massive output stages of these amps. The internal power supplies of each unit is then used for the input stage and, in the case of the PA 3100 HV, the preamp section.

Separating the big signal output circuit results in far greater fidelity as the small signal circuits are completely isolated and independent, and the output stages get a dedicated high-current transformer design. With an output of 1200 VA the PS 3000 HV is substantially more powerful than the mains unit of the A 3000 HV or PA 3100 HV itself, and can also call upon twice the reservoir capacity. The net result is a substantial improvement in the current delivery capacity and stability of the system as a whole.

The two units are connected using the special PowerLink with M 23 high-current connectors.

The Reservoir

The heart of the PS 3000 HV is a 1200 VA transformer which is encapsulated and potted in an aluminum ring. The insulating compound material completely saturates the windings and bonds them together, thereby eliminating any vibration.

Reservoir capacity comes from 24 high-performance 100 V capacitors with low inductivity for a total of 240,000 µF. Internal resistance and inductivity are further reduced by parallel wiring, with the result that the mains unit is able to deliver vast quantities of energy up to 1200 Joule and can keep up with the fastest of peak signals.

There is so much capacity, that the unit needs a soft-start to not trip your house breakers when it’s turned on. The large VU meter can be set up to display various items of information such as the power supply voltage or the current delivered.
