Black Max Power Supply for NIM Bin Specifications

4002E Black Max Power Supply for NIM Bins

INPUT 103–129 or 200–258 V ac, 47–63 Hz. An external slide switch selects nominal input voltages of 115 or 220 V ac. Changing pins on an internal connector allows operation at 88–110 V or 191–239 V ac, 47–63 Hz, with the external slide switch selecting nominal voltages of 100 or 200 V ac. Input current at 115 V ac is nominally 7 A for a 300-W dc output simultaneous with a 0.5-A, 115-V ac output. Dual fuse input uses 8-A SB U.S.A. standard fuses for 100 or 115 V ac, 60 Hz and 5-A SB metric fuses for 200 and 220 V ac, 50 Hz operation.

DC OUTPUTS Maximum rated output currents are:

DC Voltage	Maximum Current	DC Voltage	Maximum Current
+6 V	12 A	–6 V	12 A
+12 V	4 A	–12 V	4 A
+24 V	2 A	–24 V	2 A
Maximum dc output power from 0 to 50°C is 300 W. Derate 3%/°C for 50 to 60°C.

115 V ac OUTPUT Unregulated voltage. Maximum current limited only by the input fuses when operated in the 100- or 115-V ac settings. Limited to 0.5 A on the 200- and 220-V ac settings when the dc load is 300 W. Output voltage is nominally 115 V ac in the 115-V and 220-V input modes. Output voltage is nominally 100 V ac in the 100-V and 200-V input modes.

REGULATION <ą0.1% (typically ą0.05%) for ą12 V and ą24 V, and <ą0.2% (typically ą0.1%) for ą6 V over the combined range of zero to full load with the specified input voltage range for measurements made within a 1-minute period. Regulation <ą0.3% for ą12 V and ą24 V, and <ą0.6% for ą6 V over any 24-hour period at constant ambient temperature for the same load and input ranges after a 60-minute warmup.

LONG-TERM STABILITY DC output voltages change <ą0.5% (after a 60-minute warmup) over a 6-month period at constant load, line voltage, and ambient temperature.

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

TEMPERATURE COEFFICIENT <0.02%/°C, 0 to 60°C.

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

VOLTAGE ADJUSTMENT ą2% minimum range. Resettability <ą0.05% of the supply voltage.

RECOVERY TIME <100 ľs to return to within ą0.1% 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 Both input power lines include fuses. The power supply is automatically turned off by an internal switch if the temperature of the heat sinks exceeds 110°C. Recovery is automatic when the temperature decreases to a safe value. Provision is made for activating a temperature warning light on the NIM bin control panel to advise that the temperature limit is being approached. This warning occurs at and above a heat sink temperature of 95°C. All dc outputs include a current foldback circuit to limit the output current to nominally 120% of the rated value. This feature provides short-circuit and overload protection. Recovery is automatic after removal of the overload condition. Over-voltage protection for the ą 6-V outputs prevents these outputs from exceeding ą7.5 V, respectively, to protect the integrated circuits that are commonly powered by these supply voltages.

WEIGHT
Net 13.6 kg (30 lb)
Shipping 18.1 kg (40 lb)

DIMENSIONS 43.2 cm (17.0 in.) wide, 26.9 cm (10.6 in.) deep, and 8.9 cm (3.5 in.) high, except for rear-mounted, 15.2-cm-(6.0-n.-) high heat sink.

REQUIREMENTS FOR ATTACHED BIN The Model 4002E Power Supply is designed to provide very high currents to NIM modules that contain heavy loads. The NIM bin used with this power supply must be capable of handling the large currents demanded by those loads. The power On/Off switch mounted on the bin and its associated primary circuit wiring must be rated to handle 8 A. ORTEC NIM bins that can handle 8-A primary current have a label inside the bin near the On/Off switch that states "8 A Power Switch." A kit (ORTEC P/N 735110) is available to upgrade older NIM bins to an 8-A power switch. The bin wiring distributing the dc voltages must also have an impedance low enough to yield negligible voltage drops at the rated currents for the supply. Although the ORTEC Model 4001A NIM Bin will function acceptably with the Model 4002E Power Supply, the Model 4001C NIM Bin is strongly recommended as the more desirable choice. The ORTEC Model 4001C NIM Bin employs copper bus bars for power distribution. This typically results in more than a factor of 10 lower voltage drop at maximum current.
