EP-91 12 V, 1 A, Universal Input Supply
11.2 Output Voltage Start-Up Profile
Start-up into full resistive load and no-load were both verified. A 12 Ω resistor was used
for the load, to maintain 1 A under steady-state conditions.
Figure 16 – Start-Up Profile, 115 VAC.
Fast trace is no-load rise time
Slower trace is maximum load (12 Ω)
2 V, 5 ms / div.
Figure 17 – Start-Up Profile, 230 VAC.
Fast trace is no-load rise time
Slower trace is maximum load (12 Ω)
2 V, 5 ms / div.
