1. is inconvenient DC power is provided by the Model 4002P for four preamplifiers through standard 9 pin connectors on the rear panel These connectors deliver 12 and 24 V dc and are compatible with ORTEC standard preamplifier power cables as well as those of most NIM manufacturers The Model 4002P can supply power for up to 12 preamplifiers by adding an optional Model 4002P C1 Preamp Power Fan Out Cable to each connector The fan out cable converts a single preamp power output connector to three separate preamp power output connectors A standard NIM bin power connector is incorporated for supplying 12 V dc and 24 V dc to a NIM module Connection between the 4002P and the NIM module is made with the ORTEC Model 401 C3 Module Extender Cable which can be ordered as an accessory The output power is sufficient to operate a four wide NIM module and four preamplifiers Designed for international use the 4002P Portable Power Supply can accommodate input voltages of 100 120 220 and 240 V ac at 47 to 63 Hz A connector block on the rear panel is used to change and display the selected input voltage Also incorporated in this connector block are a fuse holder and the input power cord connector The 4002P uses an international standard IEC power connector to permit the use of power cords and plugs that meet local electrical standards The Model 4002P has maximum output current ratings of 1 A on 12 V 1 A on 12 V 0 5 A on 24 V a2. output voltages A power transformer transforms the input ac line voltage into four separate low voltage sources The sources or windings are full wave rectified capacitor filtered and regulated by electronic series regulator circuits The regulator circuits provide short circuit current limiting and reverse current protection Each of the four series regulator circuits are identical in operation they are physically different only in component values for each supply The regulator can operate in two modes First and normal is the voltage regulation mode second is the current foldback or current limiting protection mode The regulator will operate in the voltage regulation mode at any current output up to and including the full rated output of a particular supply When current output beyond 150 of the rated output is required which includes a direct short across the output terminals the regulator automatically converts to a current foldback mode This provides power limiting and protection of the regulator s circuitry and components When excess current demands are removed the regulator resumes the voltage regulation mode For convenience only the 24 V regulator will be discussed An explanation of the regulation in the normal voltage regulation mode is given A 6 9 V reference voltage is set by the precision reference U1 This reference voltage is divided by R3 and R4 and fed to pin 3 of the controller U2 Simultaneously
3. the output is divided by R8 R9 and R10 fed to pin 2 of U2 and compared with the voltage at pin 3 to produce an error signal at pin 6 Pin 6 of U2 drives the Darlington transistor Q1 to maintain the same voltage at pins 2 and 3 Line regulation is improved by the zener regulator D4 which receives its unregulated voltage from a voltage doubler circuit consisting of C1 C2 D1 and D2 Current flow to the output is monitored by sensing the voltage drop across R11 When the potential between pins 10 and 1 of U2 exceeds 80 mV the output current and voltage will decrease limiting the power dissipated in Q1 Capacitors C4 C16 and C5 tailor the frequency response of the system to provide excellent recovery time and output impedance characteristics D5 provides reverse current protection for the power supply and load in the event that a voltage source of the wrong polarity is connected to the output terminal If loss of the sense lead should occur pin 3 of J2 R47 provides continued operation with some loss of regulation 6 CALIBRATION AND MAINTENANCE 6 1 POWER SUPPLY DISASSEMBLY AND TROUBLESHOOTING The 4002P Power Supply needs no routine maintenance or adjustment If a problem develops and trouble shooting becomes necessary the two module side covers should be removed to provide access to the components DANGER Use extreme caution when probing inside the 4002P power supply The primary circuit is exposed in two locatio
