AC motor 2,5 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 of 115 - 230 VAC. Controls single-phase motors with a maximum combined motor current of 2.5 A. Fan speed 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. Control options: potentiometer (SPV series), Modbus I/O module, BMS system, or based on environmental parameters like temperature, relative humidity, CO2, and air quality (TVOC). Surface mountable with IP54 protection.

The SPV-8-010-PM is a potentiometer for ventilation systems with Modbus RTU communication for seamless integration. It's designed to work with a wide range of devices, including EC fans and damper actuators. Here are its key features: Universal Power Supply: Operates on a supply voltage of 85-264 VAC, 50-60 Hz, making it suitable for global use. Variable & Remote Control: The rotary knob provides manual control with an OFF-position. All parameters, including min/max settings, inverse operation, and output type (0-10 V, 0-20 mA, 0-100% PWM), can be adjusted remotely via Modbus. Remote Connectivity: It can be integrated into a Building Management System (BMS) or accessed via the SenteraWeb cloud for remote management.
