1. Each output can provide up to its maximum load separately when the power supply starts up. To exceed the maximum output power rating (200W) continuously is not allowed.
2. Each output is checked at the factory to be within voltage accuracy with a 60% rated load condition.
3. Line regulation is defined by changing the input voltage ±10% from nominal line at rated load.
4. Load regulation is defined by changing the output load ± 40% from 60% of the rated load while another output is set to 60% of rated load.
5. Ripple & noise is measured at rated load and nominal line by using a 15MHz bandwidth limited oscilloscope with each output terminated by a 0.47 microfarad capacitor.
6. Hold up time is measured from the end of the last charging pulse to when the main output drops down to 95% output voltage.
7. Efficiency is measured at rated load.
8. +12VB is floating on SNP-Z201 and can be referenced either positive (+) or negative (-).
