Soundcraft CPS-800 Replacement Power Supply with Link Cable for MH4 Series Consoles

The CPS800 is a linear power supply which, like other linear supplies, produces 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 CPS800 also has the capability of being linked to a second CPS800 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 CPS800 is designed for installation in an I9" rack unit, occupying 3U of rack height. LED indication is provided on the front panel to show operation of the regulating circuits.
