NIM CERN-CE 600W with fan tray

UEN 01 NIM Bin 7U

7U NIM-Bin for 12 high powered NIM-Modules, rugged heavy-duty construction with 6mm side panels depth 525mm. Power supply is plugged in and locked from rear side. The bin provides 2U space for a fan tray unit. The power-bus-system is equipped with 12 high-quality long-life NIM connectors parallel wired. Connector pins made of massive brass, gold plated.

Current rail system for +/-6V and Ground. Spliced wiring and additional power-connector pins have been used to allow currents of 25A for +/-12V lines now. CERN specifications are fulfilled entirely. The wiring across the NIM connectors is achieved under a screening cover.

When used according to CERN specifications the bin wiring carries mains voltage. All this mains cable are arranged as screened lines to prevent effects of mains distortions to secondary circuits. Due to not fulfilling the restrictions of EN 60950, UL 1950, etc., power supply and fan tray are not CE-marked. When used in combination with CE conform power supplies (CEP) and fan tray (CEL) mains voltage will be conducted through a separated power cord to the fan tray. This power cord is fixed at fan tray side and has to be plugged to the power supply. The bin is free of mains voltage then.

Current maximum ratings:

All NIM bins have clean earth wired with 0,25mm²

Intelligent NIM / CAMAC Fan Tray UEL03 / CEL03

• CERN spec. conform fan tray unit equipped with alphanumeric monitoring and three long life DC axial fans, either with frontal or bottom air entry (400m³/h or >540m³/h airflow).
• Static pressure up to 8 mm H2O column.
• Fan speed is variable from 1200 to 3000 rpm
• MFOT (Maintenance Free Operation Time) > 65 000h / 40°C.
• Display: voltages, currents, fan speed, air inlet temperature, total power dissipation by inserted modules, network address (if installed). In case of malfunction the type of error will be displayed.
• LED's for Status, Fan-Fail, Over-Heat
• The fan tray monitoring can be set to Programming Mode when used with PS/Cs236 or 336 power supply.
• Optionally available with CAN-bus interface for remote monitoring and control.

CE conform Crate versions / CE conform mains connection

CERN spec. wired bins allow to switch crates on and off via the mains switch at the fan tray. Current rules as CE60950 and UL1950 claim for primary to secondary isolations, which are not considered in the appropriate CERN specifications. Therefore WIENER formed a compromise to fulfill CE and UL safety restriction as well as CERN specifications by separating the mains wiring.

NIM / CAMAC Power Supply UEP 10M88 and 10M66

Linear regulated low noise power supply with 600W DC output, cut-off-protection for “overload”, “over voltage”, and “over temperature”-failures. Power Supplies »M« are equipped with monitoring, status and all alarming facilities according to CERN-CAMAC-Note 46-04. Status output »good« if all DC- Voltages are within their tolerance.

UEP 10M88 has a built in long life fan to cool heat sink, transformer and other components. The volume to power relation of high density, high sophisticated power supplies like the UEP 10M88 is extremely low for a high precision linear regulated 600W. Experience and knowledge in energy management at WIENER resulted in a special designed filter and storage capacitor bank, the “Energy-Tank” of UEP 10M. A special capacitor development with very low internal resistance and non-inductive bonding shapes the UEP 10 as a reference for power und reliability.

Different versions for either 100VAC or 115VAC or 230VAC are available.
