DVHF+2800T DC-DC Converter
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, 5V/±15V, 5.7V/±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:
- Manufactured in an MIL-PRF-38534 Class H and Class K, and ISO9001 certified manufacturing facility
- VPT’s in house legacy Class KL1 available
- 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 DVMH28 EMI filter
