Soundcraft CPS-275 Replacement Power Supply without Cable for Ghost and Ghost LE Consoles

The CPS250 are linear power supplies which, like other linear supplies, produce DC voltages by rectifying, smoothing and regulating AC voltages from the secondary windings of a mains transformer. Soundcraft mixing consoles employ a number of dc voltage supply levels in their operation and these are all provided at the output of each supply unit. The provides higher currents than the CPS250. The also has the capability of being linked to a second to provide automatic power backup in the event of one of the units failing. In regulating these voltages there is considerable heat generated, the dissipation of which is achieved through a substantial internal heat sink.

A fan is incorporated which draws air over the heatsinks to provide adequate heat dissipation for the regulators and reduce the outer case temperature. The CPS250 is designed for installation in a 19" rack unit, occupying 2U of rack height. LED indication is provided on the front panel to show operation of the regulating circuits.
