1. Default setting of JP1 is RUN, so as to enable the EP3001. If Shutdown condition is required, please
turn off the power supply and switch JP1 to SHDN. Then power on to test the Shutdown condition. Do
NOT keep JP1 floating at any time.
2. JP3 is for voltage option only. FIXED is for fixed voltage option with the marking of “A2YW”, “A3YW”,
“A4YW” and “C4YW”. ADJ is for adjustable voltage option with the marking of “A1YW”. Do NOT
change JP3 at any time.
3. JP4 is for output voltage selection for adjustable type. When AUX is selected, please see the following
section.
Output Programming
The output programming resistors for adjustable type are listed in Table 1. If AUX with JP4 is
selected, please put on R2F according to the following equation:
