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 infor mation 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.
