Autonics SPR3 three-phase thyristor power controllers – compact, reliable and ready for demanding applications, available at ELTRON

The SPR3 series are three-phase thyristor power controllers designed for industrial applications requiring efficient and precise power control. Thanks to their slim 105 mm wide housing, these devices can be easily installed even in confined spaces, making them ideal for designers of modern control cabinets and heating systems.

Equipped with a clear LED display, the SPR3 controllers enable real-time monitoring of key parameters: control signal, load voltage and current, power, resistance and heatsink temperature. Support for various control methods – phase, group and classic ON/OFF – allows the operating mode to be fully adapted to the type of load. The possibility of using feedback (constant current, voltage, power) ensures additional stability and safety of operation.

Thanks to their high energy efficiency and RS485 (Modbus RTU) communication option, SPR3 power controllers are ready for integration into advanced automation systems, including applications related to electricity transmission and distribution, heavy industry and modern production lines. Parameter configuration is easy with a computer and free DAQMaster software, which greatly facilitates implementation and service.

Built-in alarm functions – such as overvoltage protection, heater disconnection detection, heat sink overheating and diode (SCR) failure – protect both the device and the entire installation. Simple installation using brackets, quick fuse replacement and the use of high-performance SCR diodes (IXYS) make the SPR3 a complete industrial-grade solution.

SPR3 power controllers available from ELTRON meet the requirements of GPSR Regulation (EU) 2023/988, and as an authorised Autonics distributor in Poland, ELTRON ensures device availability, full technical support and professional application advice.
