6U VME64x 4500

The WIENER VME 4500 crate series is a compact new generation of 19″ integrated packaging system with frontal cooling air intake for standard VME64x bus systems with 6Ux160mm cards. Designed primarily for applications in data acquisition, control and test instrumentation it combines superior mechanical quality with lowest noise power supply technology.

Featuring microprocessor controlled power supplies and fans it provides advanced integrated diagnostic and monitoring capabilities. For remote monitoring and control the VME 4500 crates are outfitted with Ethernet, RS232 and CAN-bus interfaces.  A unique flexibility is given by the modular packaging approach. The VME 4500 crate consists of the UEV 4503 bin, the UEL 4500 fan tray unit and the UEP 4500 power supply.

Different power supply configurations as well as a variety of crate options are offered.
