The GB150S2 is a compact power supply module specifically designed for use with 2 x GB150D power amplifiers as a shared supply. It features 47,000uF of supply capacitance comprising 5 paralleled 4,700uF 63V electrolytic capacitors on each +/- V supply for lower paralleled ESR and ESL over larger single alternatives. A 10A 400V bridge rectifier is onboard as well as bleed down resistors and film bypass capacitors. A 5 way terminal block is provided for the Vs+,Vs- and 3 connections to a local low noise star ground. The PCB is double sided and through hole plated, with clearly marked component placement guide and connection labelling, and is designed to isolate input side charging spike offset currents from sensitive star ground output points. Isolated 3mm mounting holes are provided.

The long narrow shape is to facilitate the running of short supply to module wiring for lower supply impedance a common limitation on ultimate performance. The module takes wiring centrally from a single CT or dual winding transformer and outputs to each side.
