Westcor Introduces NEW EN Compliant, Low Profile, High Power Density AC-DC Switcher

The Westcor Division of Vicor Corp. has introduced the FlatPAC-EN, an ultra low profile, EN 61000-3-2 compliant power supply with a power density greater than 7.8 W/in³.

The FlatPAC-EN, measuring just 9.2 x 5.0 x 1.4 inches (233,7 x 127,0 x 35,6 mm), provides up to 500 Watts of output power from one to four isolated outputs. For full EN compliance, the FlatPAC-EN can provide up to 425 Watts. It can be configured with any of Vicor's 300 Vdc input DC- DC converters in full-, half-, or quarter-brick sizes.

Accepting inputs of 90-132 and 180-264Vac at 47-63Hz, the FlatPAC-EN uses a microprocessor-controlled auto- ranging function. Featuring passive harmonic current attenuation, FlatPAC-EN generates extremely low EMI, which greatly simplifies noise filtering and contributes to its high power density. It meets the conducted EMI requirements of FCC Class A and B and EN 55022 Class A. It also meets EN 55022 Class B with an optional AC inline connector. Like all Westcor power supplies, the FlatPAC-EN AC-DC Switcher can be factory configured to meet the specific power and voltage needs of the customer.

The FlatPAC-EN is a drop-in upgrade to Vicor's existing 2-Up FlatPAC.

Pricing for the FlatPAC-EN is as low as $1/Watt in small quantities. It is pending worldwide safety agency approvals for CE, cULus, and TÃV. Contact the factory for lead times.

The Westcor division of Vicor, located in Sunnyvale, California, designs and builds configurable AC-DC and DC- DC power supplies incorporating Vicor DC-DC converters and accessory components. For additional information on Westcor or Vicor and their products, visit the Vicor website at
