Notes:
1. Minimum voltage is guaranteed to a maximum of 0.2% of the rated output voltage.
Minimum current is guaranteed to a maximum of 0.4% of the rated output current.
2. Up to 20 MHz
3. From 5 Hz – 1 MHz
4. Time for output voltage to recover within 0.5% of its rated output for a load change from 10 to 90% of its rated output current. Voltage set
point from 10% to 100% of rated output
5. Add this to the output reponse time to obtain the total programming time
6. Time to provide data back to the controller using LAN interface (does not include A/D conversion time)
7. From 5 Hz – 1 MHz, at 10% to 100% of output voltage at full load (for 6 V units from 33% to 100% of output voltage)
