Supplemental characteristics
for all model numbers
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 kΩ 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.
Size: 425.5 mm W x 132.6 mm H x
497.8 mm D (16.75 in x 5.22 in x 19.6 in)
