NOTES: Contact factory for Safety Agency Approved status.
- Each output can provide up to peak load temporarily. Continuous operation at greater than rated load is not allowed.
- At factory, in 60% rated load condition, each output is checked to be within voltage accuracy.
- Line regulation is defined by changing ± 10% of input voltage from nominal line at rated load.
- Load regulation is defined by changing ± 40% of measured output load from 60% rated load.
- The ripple and noise is measured by using a 15MHz bandwidth limited oscilloscope. Each output is terminated with a 0.47 µF capacitor at rated load and nominal line.
- Hold up time is measured from the end of the last charging pulse to the time when the main output drops down to 95% output voltage at rated load and nominal line.
- Efficiency is measured at rated load.
