The KAM/PSU/011 converts the nominal 28V aircraft power into the voltages needed by the Acra KAM-500 backplane.
Features
- Supplies +5V, ±7V, and ±12V for backplane
- Fully isolated
- No derating with temperature (-40 to +85°C)
- Capacitor back-up: typically 24 ms, dropping from 28V @ 40W
- Reverse polarity protection
- Indefinite short-circuit protection
- EMI filtering
- Supplies up to 5A on +5V power line
Applications
- Power supplies for data acquisition systems
The KAM/CHS/06U is a six-user-slot KAM-500 chassis that includes a power supply module that regulates power supplies for the backplane.
The KAM/CHS/09U is a nine-user-slot KAM-500 chassis that includes a power supply module that regulates power supplies for the backplane.
The KAM/CHS/13U is a thirteen user-slot Acra KAM-500 chassis that includes a power supply module that regulates power supplies for the backplane.
KAM/PSU/011 Power Supply Unit
The KAM/PSU/011 converts the nominal 28V aircraft power into the voltages needed by the Acra KAM-500 backplane. The DC/DC converters used are the largest components of any Acra KAM-500 module, so the unit is split in two (one half at each end). This allows the components to be bolted to the housing and their weight to be evenly distributed in the Acra KAM-500 chassis.
The +5V supply is primarily for digital circuitry, the ±12V supply is primarily for analog circuitry, and the ±7V is exclusively for bridge excitation. Unlike other Acra KAM-500 modules the KAM/PSU/011 can only be removed by first removing the sides. The KAM/PSU/011 is only supplied as part of the housing. The green LED indicates power on the +5V power line.
Aerospace Instrumentation Brochure
Modern aerospace instrumentation systems can be highly complex, and it can be difficult to know how to meet program needs. It’s not unusual for requirements to change during a campaign and cause significant delays, and data must be captured reliably no matter what – otherwise expensive additional flights will be needed or months of program data could be lost. Read our brochure to learn how you can reduce your risk with commercial off-the-shelf (COTS) solutions.
