1. 20 MHz bandwidth. An external 2.2µf ceramic
capacitor is recommended to be placed from +V out
to -V out.
2. 12V and 24V Input models require external
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.
6. Balanced loads on dual and Aux output voltage.
7. This model includes Trim feature and unique pin
assignments. Contact factory.
