DVAB2800D DC-DC Converter

The DVAB Series is a dual output converter with zero cross regulation due to two independent control loops that provide tight regulation. Designed for use in rugged commercial avionics, military avionics, and other critical reliability power systems, the DVAB Series offers small size, light weight, and hermeticity.

 

Features:

  • Up to 15 watts output power
  • ZERO cross regulation error
  • Dual outputs of ±5, ±12, and ±15V
  • Wide input voltage range: 15 to 50 Volts with 80V transient per MIL-STD-704
  • Full performance over -55°C to +125° C military temperature range
  • Fault tolerant magnetic feedback circuit
  • Extreme reliability: no use of optoisolators
  • Host of circuit protection features
  • Extremely low profile (.355 inches) and light weight (24/28g) hermetic package
  • DLA SMD in process

Compliances and Certifications:

  • Available qualified to MIL-PRF-38534 Class H, DLA SMD #5962-14232
  • VPT’s in house legacy Class KL1 available
  • Manufactured in an MIL-PRF-38534 Class H and Class K, and ISO9001 certified manufacturing facility
  • MIL-STD-704A input voltage requirements
  • DO-160
  • MIL-STD-883 military and space environmental screening available
  • MIL-STD-461 C-G when used with a VPT DVMH EMI filter.
