Description

Electromagnetic heating with an upstream transistor amplifier

In the case of electrical control and regulating devices, there is often the requirement to increase the sensitivity of electromagnetic relays significantly »This task is particularly important when either intermediate relays are to be saved or when only extremely small control powers are available that are available Actuation of commercially available relays is no longer sufficient »

There is "the possibility of pre-amplification to amplify the control currents at will by means of electron tubes. For economic reasons', especially because of
