New Bus Converter Module

PR Log (Press Release) – Nov 02, 2009 – Now available through APC hi-rel is the new VPT Bus Converter Module. With up to 200W of output power, the VPTHVM-270 regulated bus converter module operates from a 270V bus to step down the power to create a 28V bus for avionics power systems. Engineers can use this module to power several VPT DC-DC converters.
The high efficiency design reduces input power requirements and eases thermal management.
•   Up to 200W output power
•   Single output
•   Very high efficiency - up to 91%
•   Wide input voltage range - 180 to 350V per MIL-STD-704
•   Operation over a wide -55°C to +100°C STANDARD
•   High input transient voltage - 500V for 1 second
•   Low input transient voltage - 160V for 1 second
•   Use in conjunction with any VPT DV or VPT Series 28V DC-DC converters
•   High isolation: 3000V
•    6-sided metal cases for improved EMI performance and mechanical/environmental performance
•   Parallel up to 5 units with current sharing
•   Undervoltage lockout, fixed frequency, output soft start
•   No optoisolators for ultimate reliability
•   Environmental screening including a 96 hour burn-in, 100% electrical testing, and temperature cycling testing STANDARD
•   Testing to JESD22, MIL-STD-810, MIL-STD-883
•   Designed and manufactured in a facility certified to ISO 9001, J-STD-001, and IPC-A-610
