w Your safe choice HVT 300-DP Failsafe Busbar Symmetry Monitor for +/-250 V Application Monitoring the busbar symmetry is a safety-relevant task for different processes. For instance, in hydrogen electrolysis it is crucial for optimizing the efficiency, safety, and reliability of the process, as well as for ensuring consistent and high-quality hydrogen production. Busbars distribute electrical current to the electrolyzer cells, which are responsible for the hydrogen generation process. If the busbar symmetry is not maintained, it can lead to uneven distribution of current among the cells. This imbalance can result in reduced efficiency and performance of the electrolyzer, leading to suboptimal hydrogen production or even safety risks like local overheating. The HVT 300-DP is often used in Chlorine-Alkali processes to proactively detect cell ruptures, leakages or insulation faults. Scope of use Battery Testing High power supplies Chlorine Alkaline Electrolysis Safety Features Featuring a design approach that involves thorough self-monitoring, the HVT 300-DP provides a wide range of diagnostic functions. In order to create a safety loop, the desired output must be evaluated in conjunction with one of the two diagnostic relays REL3/REL4. This way, two individually configurable safety outputs can be created, for which either the relays REL1/REL2 or the 4...20mA analog output are available.
