215 High Voltage Power Supply

The 215 high voltage supply module offers a convenient and extremely stable high voltage supply for use with detectors operating in the photo emissive (photomultipliers) and photoconductive (lead sulphide and lead selenide) modes. Designed for dedicated applications, the 215 maintains an exceptional degree of output stabilisation despite variations in temperature, mains voltage or whilst the supply is loaded and current drawn. Housed in the 417 unit, the 215 front panel permits setting and switching of the high voltage. The output voltage may be monitored via the display featured on the 417 unit. External control and switching with a micro-switch in safety interlock systems can also be implemented by application of a DC voltage.

474 Transformer & Amplifier

The 474 transformer and amplifier module is used as the lock-in amplifier front-end in AC systems for use with current generating detectors including large DC component. Given a signal having both AC and DC components, the 474 transformer allows de-coupling of the two, with the DC being blocked. Gain can then be applied to the sought-after AC signal to ensure optimal recovery. Voltage biasing of the detector used can be achieved by applying voltage across the primary coil of the transformer.
