*
Measured at the output terminals, with 1uF in parallel with supply operating at full load and nominal input line voltage.
**
RMS noise is measured directly across the output terminal with supply operating at full load and nominal input line voltage.
Sense
To compensate load cables voltage drop, units can generate 2%
additional voltage at full scale of output voltage.
Load Regulation (Specified at no load to full load change, nominal AC input)
Voltage 0.1% of maximum output voltage / current
Current 0.1% of maximum output voltage / current
Line Regulation (Specified ±10% of nominal AC input, constant load)
Voltage 0.05% of maximum output voltage / current
Current 0.05% of maximum output voltage / current
Transient Response
A 50% step load will recover to within 0.75% of original value within 1
ms.
Stability
±0.05% of set point over 8 hours at fixed line, load, and temperature,
after 30-minute warm-up
