General
The Model 4002A-P Power Supply is designed to
supply DC power to a NIM bin when the application requires ±12 V and ±24
V power. The 4002A-P Power Supply can be purchased separately for use with
existing NIM bins, or it can be ordered attached to either a 4001A-P or
4001C-P NIM Bin. The Model 4002A-P Power Supply is compatible with all ORTEC
NIM bins, and with most standard NIM bins from other manufacturers. The
4002A-P Power Supply is designed to exceed recommended power supply
specifications for Type 1 Class A supplies as defined in DOE/ER-0457T.
Regulated DC power supplied to the attached bin by the 4002A-P is rated
at +12 V @ 2 A, –12 V @ 2 A, +24 V @ 1 A, and –24 V @ 1 A. The
maximum output power is 96 W at ambient temperatures up to 50°C. In
addition, 117 V AC is available up to 0.43 A.
Protection against overload is provided in several ways. When the heat
sink temperature exceeds 82°C, the red warning indicator is illuminated
on the attached bin control panel. When the heat sink temperature exceeds
95°C, the power supply is automatically shut down, causing both the power
and temperature indicator lights to turn off. Recovery from thermal
overload is automatic when the thermal load is reduced. Output currents
from the DC supplies are internally limited to 120% of their rated values
by foldback circuits. This provides overload and short-circuit protection.
Fuses protect the ac inputs to the power supply.
Designed for international use, the 4002A-P Power Supply can accept
input voltages of 100, 120, 220, or 240 V AC at 47–63 Hz.
A connector block at the rear of the 4002A-P is used to select the
intended voltage range. The connector block also functions as a fuse
holder and power cord connector. A standard IEC line input connector
allows power cords and plugs that meet local electrical standards to be
used. Control of the primary power is provided by the On/Off switch on the
NIM bin control panel.
Connection of power and control lines to the NIM bin is provided by the
standard interface connector specified in DOE/ER-0457T. Mechanical
mounting of the power supply supply to the bin is with bolts utilizing the
standard bolt pattern specified in DOE/ER-0457T.
