The Santerno Sinus B Plus speed controller regulates fan speed and supports a single-phase input of 200–240 Vac and a three-phase input of 380 Vac, with various rated power options. Speed is adjusted using the built-in digital potentiometer or through an automation system with sensors that monitor room conditions. The OEC function helps save energy, while Soft-PWM reduces noise and annoying humming and whistling.
Control functions include controlled deceleration during brief power interruptions, emergency stop, and motor-stopped autotuning in less than one minute. Password protection, configuration via FR software on a computer, and remote inputs/outputs are also supported. Multiple self-diagnostics and protection features cover overvoltage, overcurrent, undervoltage, overload, overheating, ground and connection faults, as well as short circuits. The fan starts and stops smoothly using an adjustable time or preset speeds.
