NIM CERN-CE 300W
The CERN spec./CE NIM crate series represents modular designed NIM crates with linear regulated power supplies in excellent and proven W-IE-NE-R quality, conforming to EUR4100 and CERN specifications. These NIM crates are outfitted with 300W linear regulated, low noise plug-in power supplies for standard applications.
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.

Technical Information
UEN/CEN 03 NIM Bin 5U
Non-ventilated 525mm deep 5U NIM bin with 12 slots. Rugged heavy-duty construction with 6mm side panels depth 525mm. Power supply is plugged in and locked from rear side. 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 CEN 03 bin is free of mains voltage then.
Control panel with mains switch, mains lamp (yellow/red), LED's for status (green), overheat (yellow), overload (red), Alarm output (LEMO 00, open collector), test sockets and monitor LED's for all DC-Voltages according to CERN specifications.
Current maximum ratings:
| Voltage Line | Current / slot | Current / bin | Comment |
|---|---|---|---|
| +/-6V | 13A | 65A | sensed |
| +/-12V | 13A | 13A (optional 26A) | sensed |
| +/-24V | 13A | 13A | sensed |
| GND | 13 | ||
| 115V AC | 0.5A | Secondary |
All NIM bins have clean earth wired with 0,25mm²
NIM / CAMAC Power Supply UEP 22M
Linear regulated low noise power supply with 300W DC output, cut-off-protection for "overload", "over voltage", and "over temperature"-failures. Outfitted with same monitoring and control facilities as UEP 10M88, the UEP 22M can be used to power NIM- or CAMAC-Crates. After cut off, caused by invalid operation, reset of »M« power supplies is possible by toggling the mains switch off and on again or feeding a 24VDC signal to the "rearming" input at the monitor connector. Standard mains voltage range is 230 / 115VAC, selectable internally.
UEP 22M is foreseen for convection cooling at full output performance. Forced air-cooling can increase the total power availability up to 400W.
