Overview
The CAEN Mod.A7505B is a solution designed for operating in challenging environmental and high thermal excursions. It relies on the high efficiency PCB High Voltage power supply A7505 embedded in a custom carrier.
In order to assure its functionality for long working periods under severe environmental conditions, several dedicated technical and electrical precautions have been implemented such as stress relief techniques on cabling and soldering points, electrical redundancies, PCB layout design, and use of specific materials to minimize the thermal expansion on PCB and housing mechanics.
These features make A7505B boxes ideal for Large Area experiments where the possibility of a prompt maintenance intervention is reduced.
Safety features include:
- Overcurrent detection: if the channel attempts to draw a current larger than Iset, the output voltage is automatically adjusted to keep the current below Iset limit. Under this condition, the channel behaves as a current generator.
- Protected against short circuits, sparks and humidity.
