VXI-C size 6025
WIENER C-size VXI mainframes of the 6000 deliver highest performance and reliability. Incorporating high density & lowest noise power supply technology the 6000 VXI series is the best choice for any demanding test and measurement VXI application.
The VXI6025 “front-load” VXI-C mainframe is based on the 6000 series technology but provides full front side accessibility in a very compact chassis design. Both the power supply as well as the cooling fans are accessible and removable from the front side.
Featuring microprocessor controlled power supplies and fan trays it provides advanced integrated diagnostic and monitoring capabilities. A unique flexibility is given by the modular packaging approach.
Different power supply configurations as well as a variety of crate options are offered.

UEV 6025 VXI Front-Load Bin
The 6025 bin is a VXI-C-size mainframe configured for front-load cooling fan and power supply. Two versions are available for either medium or high power. The total height of the 6025 bin is either 8.5U ( medium power version A) or 10U (high power version B).
Common and / or isolated backplane ground connections can be user selected.
The 6000 series crates offer excellent electrical safety, i.e. no AC mains wiring is inside the bin and fan tray. All power comes from well-isolated DC low voltages (EN60950, UL1950). A Power Protect Memory (PPM) further protects the crate by preventing incompatible power supplies from powering up.

UEL6025 Fan Tray / Control Interface
The UEL6025 is the plug in fan and control unit for the 6025 VXI mainframe family.
All UEL 6025 fan trays are outfitted with long life individually controlled DC fans for front to top air flow operation. Depending on version different high performance DC fans are used.
UEL 6025 fan trays have a built-in microprocessor for fan control, communication with the power supply and display / networking. Default version is the EX type which has a high visibility alphanumeric display and combo interface (Ethernet, CAN-bus, RS232) for remote monitoring and control. This interface allows the crate, including power supply, fan tray and bin temperature sensors, to be controlled and monitored remotely via Ethernet.
A built in web server allows the crate health to be monitored via a web browser on a PC attached to the appropriate network, while SNMP provides a convenient way to tailor a control system to a given application. All network connectors are RJ45 type.

Variable fan speed is manually or remotely selectable from 1200 to >max speed. In case optional bin temperature probes are installed the fan can run in temperature-controlled mode. Running with lower fan speed all temperatures are monitored. Exceeding the first limit (user defined, default 45°C) all fans run with maximum speed in order to provide full cooling. In case the temperature passes the second limit the power supply switches off.
Adjustable “after-running” of fans continues further cooling of VXI instruments after the chassis is powered off.
The fan trays can be prepared for hot swapping.
Front panel outfitted with 4 status LED showing:
|Status||Green:||all values inside tolerance|
|Fan fail||Yellow:||one or more fans fail|
|Overheat||Yellow:||power supply overheated|
|Sys fail||Red:||VMEbus generates sysfail|
A manual SysRest button on the front panel is recessed to avoid it being pressed accidentally.
All UEL6025 fan tray monitoring can be set to Programming Mode. This feature allows all key functions and values of the power supply, like current limits and other trip off points, to be programmed. The programming can be done either locally via the front panel, or remotely via the Ethernet or CANbus interface.
UEP 6025 Power Supplies
High density, highly sophisticated modular power supplies designed with WIENER's "Low-Noise-Cavity-VHF-switching technology" which features extremely low ripple and noise (PARD) figures. This technology prevents uncontrolled RF emissions by proper internal shielding and containing of switching parts as well as an efficient deflection of magnetically induced RF currents. A well-balanced thermal design secures excellent long term stability and high MTBF.
Up to eight independent regulated DC outputs. For higher current capability, power modules can work in parallel. All outputs are floating. Therefore common- or separated grounds can be realized at backplane level (for example analog- and digital- grounds isolated).
Two types of power boxes are available: 1.5U box with 92-265VAC input for 1kW-2kW DC-output. 4U boxes offer space for a second A/C mains input (PFC) to utilize up to 4kW DC performance (230VAC mains input!). Power boxes include:
- Mains filter in connection with a power factor corrected mains input module (PFC) and soft start circuit,
- auxiliary power supply to provide monitoring and control logic as well as provide power for the fan tray,
- Monitoring and alarm circuit supported by a self-calibrating microprocessor system.
- 6 slots (1.5U box) or 10 slots (6U box) for internal power modules (DC-to-DC converters)
- Power modules and mains inputs are equipped with long life cooling fans.
Serial connections between power supply, fan tray and bin (plug & play) allows communication and exchange of data.
