VPTHVM-270 Bus Converter
With up to 200W of output power, this regulated bus converter module operates from a 270V bus to step down the power to create a 28V bus for your power system. A wide input voltage range accommodates MIL-STD-704 input power requirements for avionics, mobile, ground and other applications. The high efficiency design reduces input power requirements and eases thermal management.
Up to 200W output power
Use in conjunction with any VPT DV or VPT Series 28V DC-DC converters
Very high efficiency up to 91%
Wide input voltage range: 160 to 500 Volts per MIL-STD-704
High input transient voltage – 500V for 1 second
Low input transient voltage – 160V for 1 second
Operation over a wide -55°C to +100°C STANDARD
High isolation: 3000V
Six-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,current limit protection
No optoisolators for ultimate reliability
