The UEL03 series is a micro processor based fan tray and control
unit with multi-functional alpha numeric display. Three axial long
life DC-fans (low acoustic noise!) are used, which are mounted on on
ball bearing. Each fan is individually controlled, the fan
speed is variable from 1200 to 3000rpm.
Air inlet is either from
bottom side (>540 m3/h full cooling efficiency) or from front
side (400 m3/h). The maximum static pressure reaches <8mm water
column.
The alpha numerical display can show voltages, currents, temperatures, power consumption of inserted modules and fan speed as well as fail reasons. In programming-mode trip off-points may be adjusted, like current limits to any lower value than maximum. If these defined values are exceeded, the PS 336 trips off. (All monitoring and control facilities according to CERN-CAMAC-Note 46-04)
The front panel is outfitted with switches and LED's for:
The CEL03 is the CE conform version which has to be used with CEP/CS power supplies.
