Notes:
1. Typical efficiency measurement taken at nominal
line, full load, 25°C ambient.
2. 20 MHz BW with external 10uF/25V tantalum in
parallel with 0.1uF/50V X7R ceramic capacitor
placed across the output.
3. Total output power not to exceed 350W.
4. Requires a 2.2 uf, 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.
5. All specifications are typical at nominal line, full
load, and 25°C unless otherwise noted.
6. All specifications subject to change without
notice. Mechanical drawings are for reference
only.
7. Technical Reference Notes should be consulted
for detailed information.
8. Warranty: 1yr.
* Astec reserves the right to make changes to the information
contained herein without notice and assumes no liability as a
result of its use or application. (REV A: AUGUST 25, 2005)
