VPT Bus Converter Module
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
