Line Regulation ( with sense wires used )
(±10% of nominal AC input, constant load)
Voltage Mode: +/- 0.01% of full scale (40-800V)
Current Mode: +/- 0.05% of full scale (40-800V)
Voltage Mode and Current Mode: +/- 0.05% of full scale (10-30V)
Load Regulation (with sense wires used)
(no load to full load, nominal AC input)
Voltage Mode: +/- 0.02% of full scale (40-800V)
Current Mode: +/- 0.1% of full scale
Voltage Mode: +/- 0.05% of full scale (10-30V)
Load Transient Response
Recovers within 1ms to +/-0.75% of full-scale of steadystate output for a 50% to 100% or 100% to 50% load change
Efficiency
87% typical at nominal line and max load
Stability
±0.05% of set point after 30 minute warm-up and over 8 hours at fixed line, load and temperature, typical
Temperature Coefficient
0.02%/ C of maximum output voltage rating for voltage set point, typical
0.03%/ C of maximum output current rating for current set point, typical
Output Float Voltage
Negative terminal within +/- 300 V of chassis potential. ( We recommend the use of optional isolated analog Interface (IAI). )
Supplies in “series” have a system current limit of the lowest current supply in the system.
