CAEN VME Powered Crates are powered chassis for standard 6U x 160 mm VME modules, compliant with VME64 and VME64X specifications, ranging from full-size 21-slot crates to compact 2- or 4-slot mini crates. All models feature integrated power supplies with active protections against short circuits, overvoltage, undervoltage, and overtemperature. The Enhanced Series adds a modular hot-swappable architecture and remote monitoring via CAN bus, Ethernet, USB, and RS232 interfaces with an OLED display, while the Low Cost and Mini Crate lines provide more accessible solutions with full VME standard compliance and CBLT support.
Wide range of form factors: from 1U/2 slots up to 9U/21 slots, for benchtop setups to large 19″ rack experiments.
VME64 and VME64X compatibility: monolithic backplanes compliant with VME64 (J1/J2) or VME64X (J0/J1/J2), with Daisy Chain and CBLT support.
Modular architecture (Enhanced Series): interchangeable subrack, plug-in power supply, and 2U fan tray for easy field maintenance and upgrades.
Scalable output power: from 130 W (μ-crate) up to 2530 W (Enhanced Series), with configurable plug-in power supplies.
Remote monitoring and control (Enhanced Series): CAN bus, Ethernet, USB, and RS232 interfaces, SBC-managed with graphic OLED display.
Multiple integrated protections: short circuit, overvoltage, undervoltage, and overtemperature protection; universal 100–240 Vac, 50–60 Hz input.
Rear backplane access (VME8200): power supply positioned at the bottom, leaving the rear completely free for rear transition modules (RTM 3U/6U x 80 mm).
Software and libraries: C and LabVIEW libraries, Windows/Linux tools, OPC Server, and CAEN HV Wrapper Library.
3-year warranty on all active models.

The CAEN VME8100 and VME8200 crates are based on a modularity concept and consist of detachable parts easily to exchange. The PS is placed in order to keep the rear of the VME backplane completely accessible.

The CAEN VME8010 and VME8011 are low cost compact solutions with VME64 compliant backplane with a power distribution of +5V@60A, -12V@6A, +12V@8.9A.

The CAEN VME8004B, VME8004X, VME8008B, VME8008X and VME8001 are 4 slot VME crates with horizontal Ventilation (side to side) that provides automatic daisy chain and supports CBLT data cycles.
