PERFORMANCE

INPUT AC VOLTAGE The primary voltage selection card and indicator located in the AC POWER connector assembly permit operation with 100 V, 120 V, 220 V, or 240 V nominal input voltages. Input voltage ranges accommodated on each setting are:

FREQUENCY RANGE Operating range for ac input voltage frequency is 47–63 Hz.

DC OUTPUTS Maximum rated output currents are:

DC REGULATION Variations in dc output voltages are <±0.1% over the combined range of zero through full load and input voltages from the minimum to maximum limits of the allowed input voltage range. Measurements are made within a 1-minute period. Regulation <±0.3% over any 24-hour period at constant ambient temperature for the same load and input voltage ranges, after a 60-minute warmup.

OUTPUT IMPEDANCE <0.3 W at any frequency up to 100 kHz for the dc outputs.

NOISE AND RIPPLE <3 mV peak-to-peak for any dc output, as observed on a 50-MHz bandwidth oscilloscope.

RECOVERY TIME <50 µs to return to within ±0.1% of the rated voltage for all dc outputs for any input voltage change within the rated range, or for a change of load current from 10 to 100% of full load.

CIRCUIT PROTECTION The input ac power line is protected with a fuse (2-A fuse for 100- and 120-V ac input power; 1-A fuse for 220- and 240-V ac input power). All dc outputs include a current foldback circuit to limit the output current to nominally 150% of the rated value. This feature provides short-circuit and overload protection. Recovery is automatic after removal of the overload condition.

CONTROLS AND INDICATORS

POWER Front-panel two-position toggle switch turns power on or off. Adjacent red light indicates power On condition when illuminated. Power indicator light and output power turn off if the heat sink temperature exceeds 95°C.

INPUTS

AC POWER Rear-panel, international standard IEC power connector, type CEE-22, accepts power cables wired according to local electrical standards. A power cable is shipped with the 4002P. The CEE-22 connector meets standard 22 of the International Commission on Rules for the Approval of Electrical Equipment. The primary voltage selection card and the primary fuse are incorporated into the AC POWER connector. The primary voltage selected (100, 120, 220, or 240 V) is visible through the plastic window. U.S.A. standard in-line fuse is 2 A for 100 or 120 V ac, and 1 A for 220 or 240 V ac.

OUTPUTS

PREAMP 1, PREAMP 2, PREAMP 3, PREAMP 4 Rear-panel, 9-pin, "D" connectors (Amphenol 17-10090) provide power for up to four preamplifiers. Connectors mate with power cords on all standard ORTEC preamplifiers. Compatible with preamplifier power cables of most other NIM manufacturers. Pin assignments are listed in Table 1. Each preamp power output connector can be expanded to four output connectors by using the optional Model 4002P-C1 Preamp Power Fan-Out Cable. Using four of the Model 4002P-C1 allows the 4002P to supply power to 16 preamplifiers.

NIM POWER Rear-panel, NIM-standard bin connector compatible with the power connector on the rear of NIM modules, per DOE/ER-0457T. For use with a Module Extender Cable, such as ORTEC Model 401-C3, to power a single NIM module. Pin assignments are listed in Table 2. Pins not listed have no connection in the Model 4002P, but may be assigned to a specific function by DOE/ER-0457T.

ELECTRICAL AND MECHANICAL

DIMENSIONS 21.5 cm (8.4 in.) wide, 26 cm (10.2 in.) deep, and 10.2 cm (4.0 in.) high.

OPTIONAL ACCESSORIES

121-C1 PREAMPLIFIER POWER CABLE EXTENDER Provides a 3-m (10-ft) extension cable to connect a preamplifier power cable to the PREAMP 1, 2, 3, or 4 power output on the 4002P Portable Power Supply. Compatible with all standard ORTEC preamplifiers.

4002P-C1 PREAMP POWER FAN-OUT CABLE Plugs into a standard ORTEC preamplifier power output connector and provides four preamplifier power output connectors. Use four of the optional 4002P-C1 with the 4002P to power 16 preamplifiers.
