DEHNguard printed circuit board bases
June 2013
Electrical Power & Protection
The new range of printed circuit board bases for the DEHNguard product family opens up a variety of new possibilities for protecting power electronic devices against surges. Since the bases are directly positioned on the PCB, manual wiring for DIN rail mounted devices of this class is not necessary. Surge protection up to 40 kA is ensured at any time by simply plugging the relevant protection modules into the base part.
Higher functionality at reduced costs is a requirement that is frequently placed on developers of power electronics. This is particularly the case if the products should be internationally accepted. The lightning frequency and system qualities differ from region to region, making it even more difficult to install surge protective devices. The printed circuit board bases are an ideal solution since the connection for the surge protective device is integrated in the PCB. The efficient protective circuit that is directly situated on the PCB after the relevant protection module has been plugged in complies with the same standard as the surge protective device. This is not possible if a PCB is equipped with standard protection components such as varistors and gas discharge tubes.
By combining the bases, a variety of circuits can be realised. Thus, application-specific and customised protection is provided in combination with the protection modules. Bases are available for different system voltages for direct or alternating currents.
The cost-effective base elements, which are optionally available with remote signalling contact, considerably reduce costs for protecting electronic components against surges.
