4002A-P Power Supply

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 NIM Bin or a 4001C-P NIM Bin. The Model 4002A-P Power Supply is compatible with all AMETEK 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. 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.

    FREQUENCY RANGE 47-63 Hz. 
    INPUT CURRENT At 120 V as is typically 1.8 a rms with a 96-W load (73% efficiency).
    DC OUTPUT +12 V at 2 A, -12 V at 2 A, +24 V at 1 A, -24 V at 1 A.  Combined maximum output power 96 W at +50ºC.  Derates to 72 W at +60ºC.
    117-VOLT AC OUTPUT Limited only by the supply fuse when operating from 100 or 120 V ac.  Output is limited to 50 VA at 96-W dc load while operating from 220 or 240 V ac.
    REGULATION <±0.05% over combined range of zero to full load and input voltage of 88% to 110% of rate input over any 24-hour period at constant ambient temperature after a 60-minute warmup.
    INSTABILITY <±0.3% over a 6-month period at constant line, load, and ambient temperature after a 24-hour warmup.
    OUTPUT IMPEDANCE <0.3 Ω at any frequency up to 100 kHz.
    TEMPERATURE COEFFICIENT <0.01%/ºC from 0 to 60ºC.
    NOISE AND RIPPLE <3 mV peak-to-peak, as observed on 50-MHz bandwidth oscilloscope.
    VOLTAGE ADJUSTMENT ±0.5% minimum range; resettability ±0.05% of supply voltage (typical ±1 V).
    RECOVERY TIME <50 µs to return to within ±0.1% of rate voltage for any change in rated input voltage and load current from 10% to 100% of full load.
    CIRCUIT PROTECTION Input power line fused.  Power supply is automatically cut off by an internal switch if the temperature exceeds a maximum safe limit.  Output current foldback limiting with automatic recovery when demand is removed.
