UEP10M66 / CEP10M66 – 600W

The UEP10M66 series is a linear regulated plug-in power supply for use in CERN type NIM and CAMAC crates with 600W power output for applications with extreme +/-12V loads. This high precision and lowest noise power supply is designed as a very compact unit with extremely low volume to power relation.

This is achieved by the “Energy tank”, a special filter and storage capacitor bank assembly with low internal resistance and non inductive bonding. High reliability and cut-off protection for over load, over- / under voltage as well as over temperature failures are standard features.

The power supply is outfitted with alarming and monitoring facilities according to CERN CAMAC Note 46-04. The signals are wired on the control- and monitoring connector (15-pin sub-D / PG 27+28) and provide a status output (“good” when all DC-voltages within tolerance level), rearming input, power fail signal as well as alarms for overload and over temperature, voltage and current monitor outputs.

The UEP10M66 and CEP10M66 have to be used with CERN compatible NIM or CAMAC bins.

Technical Information

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.
