4002A 96-W Power Supply for NIM Bins
-
 Regulated dc power of ±12 V @ 2 A, and ±24 V @ 1.0 A; 117 V ac @ 0.4 A
- 96 W of dc output up to 50°C
- Operates from 100, 120, 220, or 240 V ac at 47 to 63 Hz
- Attaches to 4001A or 4001C NIM Bins
- Short-circuit and overload protected
 The ORTEC Model 4002A Power Supply is designed
to supply dc power to a NIM bin when the application requires ±12 V and ±24 V power. The
4002A Power Supply can be purchased separately for use with existing NIM bins, or it can
be ordered attached to either a 4001A NIM Bin or a 4001C NIM Bin. The Model 4002A Power
Supply is compatible with all ORTEC NIM bins, and with most standard NIM bins from other
manufacturers. The 4002A 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 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
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 is used to select the intended voltage range. The
connector block also functions as a fuse holder and power cord connector. An international
standard IEC power connector (CEE-22*) permits power cords and plugs that meet local
electrical standards to be used for the input power. 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 to the bin is with bolts utilizing the standard
bolt pattern specified in DOE/ER-0457T.
