The Model 4002D-P Power Supply is designed to supply DC power to a NIM bin when the application requires ±6 V, ±12 V, and ±24 V power. The 4002D-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. Mounting hardware is supplied to make the Model 4002D-P compatible with all ORTEC NIM bins. The Model 4001C-P NIM Bin is recommended for use with Model 4002D-P because Model 4001C-P distributes the power with copper bus bars to minimize the voltage drop at each module's power plug. The 4002D-P Power Supply is designed to exceed recommended power supply specifications for Type V-H supplies as defined in DOE/ER-0457T.
Regulated DC power supplied to the attached bin by Model 4002D-P is conservatively rated at +6 V @ 10 A, – 6 V @ 10 A, +12 V @ 3 A, –12 V @ 3 A, +24 V @ 1.5 A, and –24 V @1.5 A. These maximum output currents can be delivered in any combination, provided the total output DC power does not exceed 160 W at ambient temperatures up to 50°C. In addition, 115 V AC is available up to 0.5 A.
Protection against overload is provided in several ways. When the heat sink temperature exceeds 95°C, the red warning indicator is illuminated on the attached bin control panel. When the heat sink temperature exceeds 110°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. On the +6 V and –6 V DC supplies, crowbar circuits limit the output voltage to 7.5 V to protect integrated circuits. Fuses protect the AC inputs to the power supply.
An external slide switch allows selection of either 115 or 220 V AC as the power input. By changing pins on an internal connector, this selection can be altered to 100 and 200 V AC. 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 to the bin is with brackets utilizing the standard bolt pattern specified in DOE/ER-0457T.
