ESCRIPTIONS
The 100VFS 1 Watt DC/DC’s are specially designed to provide
ultra-high levels of isolation 3000VDC in a miniature SIP
package. The series consists of 27 models with input voltages
of 5V, 12V and 24V, and offers standard output voltages of
3.3V, 5V, 9V, 12V, 15V, ±5V, ±9V, ±12V, and ±15V for a wide choice.
The 100VFS series is an excellent selection for a variety of
applications including distributed power systems, mixed
analog/digital subsystems, portable test equipment, local
power networks and battery backed systems.
