The SU3/C power supply unit has been specifically designed for use with the CA7/C charge amplifier.
The SU3/CA7 combination has been introduced to compliment the SU2/CA6 system.
The SU3/C features separate supply & output connections instead of the phantom fed arrangement of the SU2/C. This allows for improved output impedance matching resulting in better signal transfer. The system bias voltage has been increased to 200V in line with many modern transducer requirements.
Two separate filtered outputs are provided, each giving ± 24V, 0V and an adjustable bias voltage of 0 to 200V. The outputs are available on the front panel via two 4 pole, size O, series B LEMO sockets. The bias level is set using individual potentiometers with 10 turn dials on the front panel. The bias voltage can be switched to “Standby” by a front panel mounted toggle switch. When in standby mode with the bias control set to maximum the bias voltage is nominally 20V. A red LED on the front panel indicates when the bias voltage is switched on
