PIN ASSIGNMENTS

NOTES

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 dra wings are for ref erence only.

5. Please ref er 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.
