DEHN is expanding its portfolio to include the DEHNguard M DC ACI 1250 FM, a surge arrester developed for use in HPCs and fast charging posts up to 1250V. The device is also a reliable component in DC battery storage systems.
The expansion of the charging infrastructure for electric mobility is gaining momentum. Although there is still a long way to go before charging points are available everywhere, it is crucial to protect these investments and ensure their uninterrupted operation.
Quick and easy commissioning and long-term reliable operation of the equipment are the main priority for operators and installers of charging stations. Surge protective devices such as the new DEHNguard M DC ACI 1250 FM are an essential part of the protection concept for these systems. With a protection level of 2.5kV and a short-circuit resistance of 100kA, this modular Type Two arrester is also ideal for use in battery storage systems. In addition, non-response up to 1200V fulfils the normative requirement of IEC 61851-23.
The built-in ACI technology with integrated switch-spark gap combination eliminates the need for an external back-up fuse, saving valuable space in the charging post. There is no need for complex dimensioning of back-up fuses, selectivity and connection cross-sections when designing new charging points.
The pluggable modules can be replaced quickly and easily in the event of a defect. The floating remote signalling contact on the underside of the device provides reliable information about the status of the arrester for easy remote monitoring.
