UEP 5020

 LOw Noise

The UEP 5020 series is a very high density, high sophisticated single-phase power supply for up to 8 independant outputs designed in low noise W-Ie-Ne-R - Cavity VHF-switching technology with excellent RF-shielding. This technology features strong reduced periodic and random distortions. Output power up to 3000W.

UEP5020 - 1

UEP 5020 rear side ( 3 U box)

Housing includes: mains filter, softstart circuit, auxiliary power supply, regulator-monitoring- and alarm-circuit supported by a self calibrating microprocessor system.

Weight: 10kg for 3U (with 5 modules),18kg for 6U (with 9 modules).

In case of malfunction the primary switching circuits cut off by the processor (DC-off function).
The 5020 power supply meets the CE requierments fully.
High MTBF-values are achieved by optimized thermal- balance of critical parts und the use of long life DC fans. The housing is a steel-aluminium construction.
