Stromwandler is a current transformer used to measure AC current in electrical installations. It provides galvanic isolation and steps down high currents to a safe, measurable level for meters, PLCs, data loggers and protection relays. Key benefits - Function: transforms high AC current to a low, safe signal for monitoring and protection devices; isolates measurement circuits from power circuits - Compatibility: designed to work with standard meters, relays, data loggers and control systems; suitable for panel and equipment integration - Size and form: compact form factor for space constrained panels and enclosures - Material and construction: robust housing with insulated windings for durability and safe operation - Performance: reliable current sensing across typical operating ranges with stable response and low drift in normal environmental conditions Use scenarios - In a machine control panel to monitor motor current and detect overload conditions - In a distribution board to measure branch currents for energy management and load balancing - In a protective relay input or data logger to provide an isolated current signal for fault detection
