Description

This triple output device uses two independent control loops to avoid minimum loading on the main output. The DVHF+ features outstanding regulation.

Features

  • Triple outputs of 5V/±12V and 5V/±15V
  • Extra-wide 15V to 50V input range with 80V transient
  • Up to 15W output power
  • Full performance over -55°C to +125°C military temperature range
  • Fault tolerant design with patented technology – no optocouplers
  • Extremely low profile (.355 inches) and light weight (26/29g max) fully hermetic package
  • Fixed switching frequency
  • Ensure excellent thermal performance and unit isolation by using with the thermal pad TP-007

Compliances and Certifications

  • MIL-PRF-38534 Class H and Class K certified manufacturing facility
  • MIL-STD-704A input voltage requirements
  • DO-160
  • ISO-9001
  • MIL-STD-883 military and space environmental screening available
  • MIL-STD-461 C-F when used with a VPT DVMH28  EMI filter
