NIM CERN-CE 1920W with fan tray

This CERN spec./CE NIM crate series represents modular designed NIM bins combined with high power /low noise, microprocessor controlled, switching mode power supplies in excellent and proven W-IE-NE-R quality, conforming to EUR4100 and CERN specifications. For ultimate requirements the NIM crate provides up to 1920W DC power and is outfitted with a fan tray for cooling, monitoring and control.

The modular concept of the CERN NIM and CAMAC standard allows to easily insert / remove and exchange fan trays (if outfitted with) and power supplies. All CERN spec. parts as bins, fan trays and power supplies are interchangeable between different NIM and even CAMAC crates. All power supplies support the features defined by the CERN standard including the monitoring connector and provide protection against short circuit, over / under voltage and over temperature.

The “CE“ versions provide improved AC wiring.

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:

Voltage Line Current / slot Current / bin Comment
+/-6V 13A 65A sensed
+/-12V 13A 26A sensed
+/-24V 13A 13A sensed
GND 13    
115V AC   0.5A Secondary

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

Intelligent NIM / CAMAC Fan Tray UEL03 / CEL03

  • 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.

PS/CS 336 Low noise switching CAMAC Power Supply

High density ultra high power CAMAC power supply in WIENER low-noise-cavity technology, considering both: CERN-CAMAC-Note 46-04 and EP 82-01. The PS236 power supplies use the status signal to superpose additional digital monitoring information to the fan tray. This enlarged the monitoring and control features. Wide range mains input 92-265VDC, 47-63Hz.

DC Outputs:   +/-6V, +/-12V, +/-24V. Current limits can be adjusted via UEL/CEL03 fan tray or remotely, when the fan tray has corresponding remote interface installed.
