AC motor 2,5 A | remote fan speed control | TK monitoring

Transformer fan speed controller with Modbus RTU communication for manually or demand-based fan speed regulation. The supply voltage ranges from 115 to 230 VAC. It is used for single-phase motors. The maximum motor current (combined) is 2.5 A. Modbus communication is used to control the RTVS8 serie. The fan speed is controlled by gradually varying the motor voltage. The autotransformer technology produces a perfect sinusoidal motor voltage. This ensures that the motor runs quietly. The electrical noise from the autotransformers is reduced by a special impregnated coating. To adjust the requested fan speed a potentiometer (SPV series), Modbus I/O module, or BMS system can be used. The fan speed can also be adjusted based on the temperature, relative humiudity, CO2 and air quality (TVOC). Surface mounting is possible (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. The SPV-8-010-PM doesn't just stop at performance—it's built to withstand the elements. Housed in a splash-proof enclosure, it offers the flexibility of both inset mounting (IP44) and surface mounting (IP54). This ensures durability and reliability, even in challenging environments.
