Notes:
1. 20 mHz bandwidth. An external 2.2 mf ceramic capacitor is recommended to
be placed from +V out to -V out.
2. Requires a 2.2 mf, 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 spec-
ifications.
3. All specifications are typical at nominal line, full load, and 25°C unless
otherwise noted.
4. All specifications subject to change without notice. Mechanical drawings are
for reference only.
5. Please refer to the Technical Reference Notes for more information.
