| Content: | Author: Johann Eckl Dear Pippo, as you might already know we also had a breakdown of our PMT-MCP210 this year. The device worked fine since 2010. However, after slightly increasing the bias voltage (from -4600V to -4900V) in 2014 the device got damaged after a short periode of time. As far as i can remember there is also a current limitation during switch-on time. Unfortuately, i can not remember the specified value. Our power-supply is limited to 220µA. Best regards from Wettzell, Johann |
