Virtual Four Pole Power Supply

If you only need two channels we recommend the smaller (and cheaper) Predator supply as a better match.

Features

• 100.000uF Low Impedance capacitors, connected in a V4P network.
• Ultra Fast Recovery (25 ns) rectifiers
• Soft Start Circuit
• DC Filter (prevents transformer hum).
• On Board Gate Driver Regulator.
• One Module Does it All

The principle of Virtual Four Pole Networks

Here you can see the principle of V4P networking capacitors. All caps are synchronously charged or discharged, and none of the caps exchange charge currents. Every capacitors equivalent series resistance is about 100 milliohms, but the combined series resistance to the neighbour capacitor is about 200 milliohms. So no capacitor can exchange currents with the others.

The 8 Ultra Fast rectifiers are placed on small separate heat sinks. In front of the picture you see the Soft Start relay, which enforces a slow cut in to the mains grid, avoiding stress to the rectifiers, switches and capacitor

banks. The big black capacitor in front of the picture is a DC blocking cap, it prevents DC components of the mains grid to reach the primary winding of the main transformer that would cause it to hum.

The wiring to the modules is very simple. Note, we have removed one capacitor from the ZapPulse module on this picture, to give you a better view of the wiring.

We recommend a transformer of 2 X 42 V AC secondary, 500 VA to drive 4 ZapPulse modules, and two 500 VA's for 5 to 8 channels.
