Crate Specifications

Dimensions:  19" rackmount,  12.25"

     height, 21.75" depth.

Voltage Meter: Digital meter  provides

     monitoring of all output

     currents and voltages.

Cooling:   Six high capacity fans.

Weight:   39 lb. (17.7 kg)



Power Specifications

Total Power: 700W maximum +/-6V,+/-12V,

     +/-24V combined



Maximum output currents from:

+/- 6V:   Up to 60 Amps from either

     supply.90 Amps  combined

     sum. See Graph 2.

+/- 24V:   8 Amps maximum  each.

     Subtract current drawn by







 +/- 12V:   4 Amps maximum each. Derived from +/- 24 V supply.



 Note: 1)  All models provide current foldback limiting and over voltage

     crowbar protection for all output voltages.

   2)  On all models the +/-l 2V is derived from +/- 24V sources.



 Performance

 Ripple:        <15 mV peak-to-peak (50MHz bandwidth).

 Regulation:       +/- 0.01 % line or load ( at the sense leads).

 Temperature Coefficient:   < 0.1 %/degC.

 Long Term Stability:    < 0.1 %/24 hours at constant load and

          temperature. Measured after 1 -hour warmup.

 Tracking:       During turn-on all six output voltages rise

          together. Risetime 10 msec.

 General

 Overload Protection:  All outputs are protected against overload by current

       limit circuits. Short circuit proof. All outputs switch off

       within 20 msec of detected overload.

 Overvoltage Protection: All outputs are protected against transient overvoltages

       by high current transient suppressors.

 Thermal Protection:  A thermal sensor shuts down the supply in the event of

       a thermal overload. A front-panel thermal overload light

       on the blower module indicates an overtemperature

       condition in the power supply.

 Operating  Range:  Full 700 W output from 0 deg C to 40 deg C ambient

       temperature. Derate at -15 W/degC above 40 deg C.

       Maximum ambient temperature 50 deg C. See graph 1.
