Integrated power monitoring provided by the Transclinic monitoring system enables errors to be diagnosed accurately. This means you can optimise specific parts of your system and reduce maintenance costs considerably.Transclinic complies with all the latest standards and comes with two digital inputs for monitoring switch settings and surge protection. Special feature: depending on the version, up to two strings can be monitored via a single channel.
The unique, self-supplying power supply unit Transclinic BKE enables power to be supplied directly from the DC voltage of the PV system. Additional wiring for a local AC supply is not required. This simplifies installation and maintenance of the entire system.
With fuses on the positive and negative side of each string, we guarantee the highest security for your system and peripherals.
Surge protection systems from Weidmüller have proven themselves in many different industries and are therefore a standard feature in our combiner boxes.Optimum protection for each specific application is carefully selected by our application engineers and incorporated in the design.The products used comply with current standards and have been developed specifically for, amongst other things, the DC side of photovoltaic systems.
Our WFF bolt-type screw terminals allow an easy, flexible and handy assembly for DC output cables from 10 mm² to 300 mm².
The WM4 C is our modern crimp connector. It combines outstanding quality with ease of handling and is available as a field or housing connector. The standard “Type 4” connector face allows it to be used with Weidmüller's entire range of connectors.
