UEP6021
The UEP 6021 Power Supply is a very high density, high sophisticated microprocessor controlled modular power unit. It is designed in WIENER “Low-Noise-Cavity-VHF-switching technology” which features extremely low ripple and noise (PARD).
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.
Excellent balanced thermal design secures extraordinary long time stability and high MTBF. Up to 3kW (3Ubox) or 6kW (6Ubox) DC output power can be provided. The modular design with programmable power modules (DC-to-DC converters) allow it to be tailored to any application or chassis requirements..

Technical Information
UEP 6021 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). Wide compatibility ranges become possible by automatic programming of voltage levels and current limits to reference-values that are stored in a bin-memory (Power Protection Memory, PPM system). Incompatibility between bin/backplane and power supply prompts the PPM to keep the power supply off.
Two types of power boxes are available: 3U box with 92-265VAC input for 1kW-3kW DC-output. 6U boxes offer space for a second A/C mains input (PFC) to utilize up to 6kW 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.
- Five, six (3U box) or 10 slots (6U box) for power modules (DC-to-DC converters)
- CAN-bus interface, processing all power supply, fan tray, and bin data
- 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 between all crate.
