Notes:
1 With sense terminal connected.
2 Following a change in output current from full load to half load or vice versa.
3 Maximum time required for the output voltage to change from 1% to 99% or vice versa after receiving a VOLTage or VSET command via GPIB or USB interface.
4 Average time for output to start to drop after OVP/OCP condition occurs.
5 Maximum time for output to change after receipt of commands.
