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 specifications.
3. All specifications are typical at nominal line, full load,
and 25C 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
