Soundcraft CPS-2000 Replacement Power Supply without Cable for MH4 Series Consoles

The CPS2000 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.In regulating these voltages there is considerable heat generated. the dissipation of which is achieved through a substantial heat sink on each side of the unit. Two fans are incorporated which draw air over the heatsinks to provide adequate heat dissipation for the regulators and reduce the outer case temperature.

The CPS2000 is designed for installation in a 19" rack unit, occupying 4U of rack height. LEDs are provided on the front panel to show the operation of the regulating circuits and a digital voltmeter monitors the mains supply voltage. The CPS2000 may be linked to a second CPS2000 to provide automatic power backup in the event of one of the units failing.
