AC motor 5 A | remote fan speed control | TK monitoring

Transformer fan speed controller with Modbus RTU communication. Designed for manual or demand-based fan speed regulation. Supply voltage: 115 - 230 VAC. Controls single-phase motors with a maximum combined motor current of 5 A. Control options: Sentera HVAC sensors (temperature, relative humidity, CO2, air quality/TVOC), potentiometers (SPV series), Modbus I/O modules, or BMS systems; allows both manual and automatic adjustment. Fan speed is regulated by gradually varying motor voltage using autotransformer technology, ensuring perfectly sinusoidal motor voltage for quiet operation. Special impregnated coating reduces electrical noise from the autotransformer. Surface mountable with IP54 protection.

Introducing the SPV-8-010-PM, a revolutionary potentiometer that redefines manual control for ventilation systems. With Modbus RTU communication, this device offers seamless integration into various applications, providing users with unparalleled flexibility. Designed for global compatibility, the SPV-8-010-PM operates on a supply voltage of 85-264 VAC at 50-60 Hz. This broad range ensures adaptability to almost any mains power worldwide, making it a reliable choice for diverse environments. This potentiometer takes control to the next level by managing EC fans, AC fan speed controllers, or damper actuators. Choose from a range of output types, including 0-10 V, 0-20 mA, or 0-100% PWM while a simple twist counter-clockwise to its OFF-position disables the control signal. Its versatility extends to settings such as normal or inversed operation, minimum and maximum settings, and output overwrite. Access all these features effortlessly through the Modbus registers, offering a customizable experience tailored to your specific needs. Thanks to Modbus RTU, the SPV-8-010-PM can be accessed remotely via a Building Management System (BMS) or through the SenteraWeb cloud. This connectivity opens up a world of possibilities, from standalone usage to becoming an integral part of a comprehensive ventilation management system.
