NOTES
1. 20 mHz bandwidth. An external 2.2
µf
ceramic
capacitor is recommended to be placed from +V out
to -V out.
2. Requires a 2.2
µf,
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 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.
