1. 20 mHz bandwidth. External 10 uF tant. capacitor + 0.1 uF
cer. capacitor 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 25°C
unless otherwise noted.
4. All specifications subject to change without notice. Mechanical
drawings are for reference only
5. Technical Reference Notes should be consulted for detailed
