The heavy notes on the schematic denote the primarysignal path.2. Unless otherwise noted, all voltages indicated on theschematics are measured under the following conditions:a. AC input at 120 volts, 50/60Hz.b. All voltages are +/-10% with respect to ground. Ahigh impedance (10 megaohm) voltmeter must be used.3. Unless otherwise specified:a. Resistor values are in ohms.b. Capacitor values are microfarads (uF).c. Inductor values are in microhenries (uH).4. On PC board drawings, Square pad indicates:a. Polarized Capacitors - Positiveb. Diodes - Cathodec. Others - Pin 15. WARNINGParts marked with the symbol have criticalcharacteristics. Use only replacement parts recom-mended by the manufacturer.6. Soft startup procedure for servicing:1. Interconnect output module and power modules2. Connect Output Module to 120VAC3. Connect Power Modules to variac and set theoutput to zero.4. Turn Output Module power switch to on. (This willenergize the power relays in the Power Modules.)5. Gradually advance the variac to 120VAC whilemonitoring the AC current.NOTESRadioFans.CN 收音机爱 好者资料库3REAR PANELSECTION LOCATIONTOP VIEW WITH COVER REMOVEDMC2KWPOWER4BLOCK DIAGRAMINTERCONNECTMC2KWOUTPUT56178AMP 050215 SCH2AMP 050215 PCB2910HEATSINK 050216 SCH3AMC2KWPOWER3BHEATSINK 050216 PCB3A11123BHEATSINK SLAVE 050282 SCH4A 4BJ2R2R5129610J4J6GP2GP3R4R7R1GP1R3J1R6GP4J5R13R15Q11R21R23Q19C10R14Q10R16R20RT1R22Q18C11J3Q9R19R17Q17Q15Q13R12Q8R18Q12Q14Q16TOREDRev.ABLUMASTER HSGRNMC2KWPOWERHEATSINK SLAVE 0502824A 4B134343113434-80VJ6-80VJ680VJ580VJ5GRNREDGP180V-80V-80V-80VJ6J680V80VJ5J5RECT-J2RECT+J1J7J8J9J10J3J4J5J6C167000uFC267000uF+J7J8J10129592J1J3J5J4J9J6J2GP1REDREDGRNGRNREDGRNRev.AREDREDGRNGRN5CAPACITOR 05021714LOGO 0502186AB+15V6B6B22NC15V6B2215V15V15VGREENGREENJ5:2J5:1J5:2J5:115VGREENDS71.65kR4DS51.65kR3GREENDS11.65kR11kR915VJ5:3J5:4J5:3DS21.65kR2GREENGREENLOGO1J2:1LOGO1LOGO1J1:1GREENDS8DS6GREENDS3J2:3J2:215VJ1:4J1:2J1:3DS4MC2KWPOWER15S9B+NCLOGO26AJ2:36AJ2:2D6AJ2:1J5:3J5:1J5:2LOGO 0502186B16PARTS LISTINTERCONNECTT1POWER TRANSFORMER050230D1DIODE BRIDGE RECT070181RT1ASSY THERMISTOR052017RT2ASSY THERMISTOR052017CBCIRCUIT BREAKER 20A 240V088022AMPLIFIER PCB 050215C1CAP MONO 10PF 200V 10%061297C2CAP ELECT 100UF 25V066447C3CAP MONO .1UF 50V 20%061305C4CAP MONO .1UF 50V 20%061305C5CAP MONO .1UF 50V 20%061305C6CAP ELECT 10UF 50V066445C7CAP ELECT 22UF 100V066506C8CAP MONO .1UF 50V 20%061305C9CAP MONO .1UF 50V 20%061305C10CAP ELECT 10UF 50V066445C11CAP ELECT 100UF 25V066447C12CAP ELECT 10UF 100VDC066462C13CAP MONO 1PF 100V NPO061319C14CAP ELECT 10UF 100VDC066462C15CAP MONO 220PF 200V 10%061301C16CAP MONO 470PF 100V 10%061302C17CAP MONO 1000PF 50V 10%061303C18CAP MONO 1000PF 50V 10%061303C19CAP MONO 100PF 100V 10%061300C20CAP MONO 100PF 100V 10%061300C21CAP ELECT 220UF 25V066507C22CAP MONO 47PF 200V 10%061299C23CAP MONO 47PF 200V 10%061299C24CAP MONO 47PF 200V 10%061299C25CAP MONO .1UF 50V 20%061305C26CAP MONO .1UF 50V 20%061305D1DIODE SILICON070047D2DIODE SILICON070047D3DIODE SILICON070047D4DIODE SILICON070047D5DIODE SILICON070047D6DIODE SIL 400 PIV 1.5A070031D7DIODE SIL 400 PIV 1.5A070031D8DIODE SILICON070047D9DIODE SILICON070047D10DIODE SILICON070047J1HDR SHROUDED 2ROW 26PIN V117870J2CONN 3 POS M MTS100 NRML117214J3CONN 8 POS M FRICTION LOCK117275J4CONN 8 POS M FRICTION LOCK117275J5CONN 3 POS M MTS100 NRML117214J6BLADE FASTON W/FEET117708J7BLADE FASTON W/FEET117708J8HEADER 8 PIN MTA-156117717J9HEADER 8 PIN MTA-156117717J10BLADE FASTON W/FEET117708J11BLADE FASTON W/FEET117708J12BLADE FASTON W/FEET117708J13BLADE FASTON W/FEET117708J15CONN 4 PIN117215J16BLADE FASTON W/FEET117708K1RELAY POWER 24VDC/TV-15087042Q1TRANSISTOR PNP132224Q2TRANSISTOR PNP POWER132255Q3TRANSISTOR NPN132223Q4TRANSISTOR PNP132224Q5TRANSISTOR NPN132223Q6TRANSISTOR PNP132224Q7TRANSISTOR PNP132224Q8TRANSISTOR PNP 2SA1321C132286Q9TRANSISTOR NPN 2SC3334C132285Q10TRANSISTOR N JFET132222Q11TRANSISTOR N JFET132222Q12TRANSISTOR SI NPN 25V132254Q13TRANSISTOR PNP POWER132255Q14TRANSISTOR PNP132224Q15TRANSISTOR NPN132223Q16TRANSISTOR SI NPN 25V132254Q17TRANSISTOR PNP POWER132255Q18TRANSISTOR NPN132223Q19TRANSISTOR PNP132224Q20TRANSISTOR SI NPN 25V132254Q21TRANSISTOR PNP POWER132255Q22TRANSISTOR NPN 2SC3334C132285Q23TRANSISTOR PNP SILICON132172Q24TRANSISTOR PNP 2SA1321C132286Q25TRANSISTOR NPN 2SC3334C132285Q26TRANSISTOR NPN SILICON132171Q27TRANSISTOR PNP 2SA1321C132286Q28TRANSISTOR PNP 2SA1321C132286Q29TRANSISTOR NPN 2SC3334C132285Q30TRANSISTOR NPN132223Q31TRIAC OPTOCOUPLER131024Q32TRANSISTOR PNP SILICON132172Q33TRANSISTOR PNP 2SA1321C132286Q34TRANSISTOR NPN 2SC3334C132285Q35TRANSISTOR NPN SILICON132171Q36TRANSISTOR NPN132223R1RES MF 47.5K 1% 1/4W144108R2RES MF 2.21K .5% 1/4W144396R3RES MF 2.21K .5% 1/4W144396R4RES MET OX 430 OHM .5W 5%137095R5RES MF 47.5K 1% 1/4W144108R6RES MF 4.75K 1% 1/4W144097R7RES MF 475 OHM 1% 1/4W144086R8RES MF 47.5K 1% 1/4W144108R9RES MF 1.91K .5% 1/4W144395R10RES MF 47.5K 1% 1/4W144108R11RES MF 1.91K .5% 1/4W144395R12RES MF 221K 1% 1/4W144421R13RES MF 475 OHM 1% 1/4W144086R14RES MF 100 OHM 1% 1/4W144196R15RES MET OX 430 OHM .5W 5%137095R16RES MF 100 OHM 1% 1/4W144196R17RES MF 1K 1% 1/4W144090R18RES MF 100 OHM 1% 1/4W144196R19RES MF 100 OHM 1% 1/4W144196R20RES MF 3.32K 1% 1/4W144095R21RES MF 2.21M 1/4W144265R22RES MF 1K 1% 1/4W144090R23RES MF 475K 1% 1/4W144364R24RES MET OX 47 OHM .5W 5%137096R25RES MET OX 680 OHM .5W 5%137093MC2KWPOWER17Ref.
