Product Description
High efficiency
Built-in EMI filtering
The PFM in a VIA package is a highly advanced 400W AC-DC
converter operating from a rectified universal AC input which
delivers an isolated and regulated Safety Extra Low Voltage (SELV)
24V secondary output.
Chassis-mount or board-mount packaging options
Always-on, self-protecting converter control architecture
SELV Output
This unique, ultra-low-profile module incorporates AC-DC
conversion, integrated filtering and transient surge protection in a
chassis-mount or PCB-mount form factor.
Two temperature grades including operation to –40°C
Robust package
The PFM in a VIA package enables a versatile two-sided thermal
strategy which greatly simplifies thermal design challenges.
Versatile thermal management
Safe and reliable secondary-side energy storage
High MTBF
When combined with downstream Vicor DC-DC conversion
components and regulators, the PFM in a VIA package allows the
Power Design Engineer to employ a simple, low-profile design
which will differentiate his end-system without compromising on
cost or performance metrics.
