21、IS APPARATUS MUST BE EARTHED 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

22、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

23、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. Refer to the section RECOMMENDATIONS FOR INSTALLATION on Page 7. LEDs are provided on the front panel to show the op

24、eration 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. MAINS VOLTAGE SELECTION. Special attention should be paid to the following informat

25、ion: Do not change the voltage setting without first turning the unit off and unplugging the mains lead. Ensure that the cover plate over the mains voltage selection switches is replaced after correct voltage selection has been made and that the cover plate is positioned to show the correct mains vo

26、ltage. This unit is capable of operating over a wide range of mains voltages by means of a comprehensive set of selectable voltage settings. It is important to ensure that the correct voltage setting has been selected for the level of local mains voltage supply, for safe, uninterrupted operation of

27、the unit. There are two mains voltage selection switches behind a cover plate on the front of the unit. Voltage selection is achieved by moving the switches using a screwdriver blade, into the correct positions, as shown by the symbols marked on the front panel. In this way the unit is set up for op

28、eration at one of the following ranges of mains supply: NOMINAL VOLTAGE OPERATING VOLTAGE RANGE Vrms AC Vrms AC 230195-253 200 170-220 11598-126 100 85-110 Introduction3 200V 230V 100V 115V Mains Voltage Selector Positions CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN RISK OF ELECTRIC SHOCK DO NOT OPEN

35、ONLY. Front and Rear Panel Views 4Introduction OPERATING VOLTAGE RANGE It is very important to use the correct mains voltage selection. A wide operating range of mains voltages is provided to enable the unit to function down to only 85Vrms on the mains supply. This facility is incorporated to overco

36、me the problems that some power supplies have with internal regulation when operating from a poorly regulated mains supply. Do not operate the PSU with a consistently high (above nominal) reading on the mains meter. Operation with the mains higher than +10% may cause serious damage The mains meter i

37、s essentially a peak-reading device, as it is the peak value of the mains waveform which is the most important factor in providing the correct mains voltage to the power supply. For this reason, and because with long power cables it is common for the mains waveform to become distorted, the indicatio

38、n of the meter may not agree with readings taken with the usual types of quasi-RMS reading testmeter. Note that the meter measures the voltage actually available at the PSU, and therefore will indicate any voltage drop on mains supply wiring. REPLACING MAINS FUSE. In the event of incorrect switching

39、 of the mains voltage selectors, a mains power surge or underrated fuse value, the mains fuse in the front panel will blow and the CPS2000 will not function. Switch the ON/OFF switch to the OFF position. Check the fuse and replace if necessary; also check that the voltage selection is correct for th

40、e mains supply level before switching the unit ON again. To avoid risk of fire replace only with the correct value fuse, as indicated on the unit. In the event of repeated failure of the mains fuse consult the Soundcraft dealer from where the unit was purchased. This unit contains no user serviceabl

41、e parts. Refer all servicing to a qualified service engineer, through the appropriate Soundcraft dealer. Introduction5 1Soundcraft is a trading division of Harman International Industries Ltd.
