Notes:
1. Typical efficiency measurement taken at nominal
line, full load, 25C ambient.
2. 20 MHz BW with external 10uF/25V tantalum in
parallel with 0.1uF/50V X7R ceramic capacitor
placed across the output.
3. Total output power not to exceed 350W.
4. Requires a 2.2 uf, 100V film capacitor connected
between +V in and -V in to meet FCC class A
and ETS300-386-1 requirements for conducted
noise. Consult Factory for filtering information to
meet FCC class B, VDE or EIC specifications.
5. All specifications are typical at nominal line, full
load, and 25C unless otherwise noted.
6. All specifications subject to change without
notice. Mechanical drawings are for reference
only.
7. Technical Reference Notes should be consulted
for detailed information.
