Supplemental characteristics for all 655x 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 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.
Size	425.5 mm W x 132.6 mm H x 497.8 mm D (16.75 in x 5.22 in x
