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 4 A for a 160-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 fro 200 and 220 V ac, 50 Hz operation. |

Maximum dc output power from 0 to 50ºC is 160 W. Derate 3%/ºC for 50 ti 60ºC.
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 160 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 |
<±0.1 % (typically ±0.05%) for ±12 V and ±24 V, and <0.2% (typically ±0.1%) for ±6 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 <±0.3% for ±12 v and ±24 V, and <±0.6% for ±6 V over any 24-hour period at constant ambient temperature fro the same load and input ranges after a 60-minute warmup. |
LONG-TERM STABILITY |
DC output voltages change <±0.5% (after a 60-minute warmup) over a 6-month period at constant load, line voltage, and ambient temperature. |
OUTPUT IMPEDANCE |
<0.3ΩΩ at any frequency up to 100 kHz for the dc outputs. |
TEMPERATURE COEFFICIENT |
<0.02%/ºC, 0 to 60ºC. |
NOISE AND RIPPLE |
<3 mV peak-to-peak for any output as observed on a 50-MHz bandwidth oscilloscope. |
VOLTAGE ADJUSTMENT |
±2% minimum range. Resettability <±0.05% of the supply voltage. |
RECOVERY TIME |
<100 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. |
CIRCUITPROTECTIONS |
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 110ºC. 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 95ºC. All dc outputs include a current foldback circuit to limit the output current to nominally 120% of the rate value. This feature provides short-circuit and overload protection. Recovery is automatic after removal of the overload condition. Over-voltage protection for the ±6-V outputs prevents these outputs from exceeding ±7.5 V, respectively, to protect the integrated circuits that are commonly powered by these supply voltages. |

RECOMMENDATIONS FOR ATTACHED BIN |
The 4002D-P Power Supply is designed to provide 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 related to handle 5 A. 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. The Moded 4001A-P NIM Bin will function acceptably with the 4002D Power Supply, but the Model 4001C-P NIM Bin is recommended as the more desirable choice. The Model 4001C-P 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. |
