AC motor 7,5 A | remote fan speed control | TK monitoring

Transformer fan speed controller with Modbus RTU communication. Supply voltage is 115 - 230 VAC. The maximum motor current is 7.5 A The RTVS8 series is controlled via Modbus communication. The required fan speed can be set using Sentera HVAC sensors, potentiometers (SPV series), Modbus I/O modules or BMS systems. The fan speed can be controlled manually or depending on temperature, relative humidity, CO2 and air quality (TVOC). The fan speed is adjusted by gradually changing the motor voltage. Autotransformer technology produces a perfectly sinusoidal motor voltage. This ensures quiet operation of the motor. A special impregnated coating reduces electrical noise from the autotransformer. The housing can be surface mounted (protection class IP54).

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.
