VT874

The VT874 provides three AMC mid-size slots that can accept any AMC.1, AMC.2, AMC.3 and/or AMC.4 with accompanying clamshells for conduction cooling

The VT874 is designed for the rugged extremes of avionics, naval, and ground vehicles applications. It can withstand extreme environmental conditions such as temperature, shock, vibration, corrosion and EMI. The unit can also be utilized in other rugged applications such as pole-mount communications, energy sector rigs/stations etc. Each chassis side wall includes a 7.2" x 4.7" pocket to mount a heat sink via a six 8-32 UNC-B insert bolt pattern.   Provision allows for an optimum heat sink/cold wall thermal design for both the AMC payload configuration and deployed environment.

The front cover panel accommodates MIL style M38999 connectors and can be customized to meet each customer’s unique requirements. Contact VadaTech to discuss your application

FRU Information and Carrier Locator

The VT874 has dual redundant FRU information and Carrier Locators. The Carrier Locator is assigned by mechanical dip switches which are easily accessible. The MCH reads the Locator via its private I2C bus.

Conduction Cooled Chassis and Front Cover

The VT874 is made from lightweight aluminum 6061-T6 and includes a hinged front cover, allowing it to remain intact while serviced in the field. Conduction cooling is achieved through precision-machined card guides in the side walls. The cover utilizes stainless steel captive hardware and self-locking heli-coils to withstand maximum shock and vibration.

No Active Components

Unlike other MTCA chassis, the VT874 has no active components on its back plane. This allows for ease of serviceability.

Scorpion™ Software

VadaTech’s Scorpionware software can be used to access information about the current state of the Shelf or the Carrier, obtain information such as the FRU population, or monitor alarms, power management, current sensor values, and the overall health of the Shelf. The software GUI is very powerful, providing a Virtual Carrier and FRU construct for a simple, effective interface.
