(at 0˚ to 55˚ C unless otherwise specified)
Constant-voltage, constant-current operation
Complete front-panel control calibration and display
Remote programming and sensing
Fan-speed control to minimize acoustic noise
Low ripple and noise
Over-voltage and over-current protection
dc Floating Voltage: Output terminals can be floated up to ±240 Vdc
from chassis ground
Remote Sensing: Up to half the rated output voltage can be dropped in
each load lead. The drop in the load leads subtracts from the voltage
available for the load.
Output Programming Response Time: The rise and fall time (10/90% and
90/10%) of the output voltage is less than 15 ms. The output
voltage change settles within 1 LSB (0.025% x rated voltage) of
final value in less than 60 ms.
Down Programming: An active down programmer sinks approximately
20% of the rated output current
Modulation: (Analog programming of output voltage and current)
Input signal: 0 to –5 V
Input impedance: 10 k Ohm nominal
ac Input: (ac input frequency 47 to 63 Hz)
Voltage 100 Vac 120 Vac 220 Vac 240 Vac
Current 12 A 10 A 5.7 A 5.3 A
Input Power: 1,380 VA, 1,100 W at full load; 120 W at no load
Regulatory Compliance: Listed to UL 1244; certified to CSA556B;
conforms to IEC 61010-1. See page 73 for more information.
Size: 425.5 mm W x 132.6 mm H x 497.8 mm D (16.75 in x 5.22 in x
