Single phase transformer fan speed controllers
Single-phase transformer fan speed controllers adjust the speed of single-phase fans by changing the output voltage using an autotransformer. This method ensures smooth and efficient fan operation, tailored to different speed requirements. These controllers are designed to meet the needs of various ventilation systems, both in residential and commercial settings.
Our controllers offer the option to connect motor protection through built-in TK (thermal contacts) in the motor. This safety feature protects the motor from overheating, ensuring durability and reliable performance even under heavy or prolonged use. This is especially important for low-power fans that often face continuous workloads. The construction of these controllers is robust and long-lasting, while installation is simple and user-friendly. Transformer controllers operate quietly, producing minimal electromagnetic noise, making them ideal for sensitive environments such as hospitals, offices, or schools. The step-by-step speed adjustment allows for precise fan control while also reducing energy consumption.
Single-phase transformer fan speed controllers are not only a reliable and cost-effective solution but also an essential tool for ensuring the efficient operation of ventilation systems and motor protection. This solution promotes durability, reliability, and optimal performance in any application.
TRANSFORMER FAN SPEED CONTROLLERS | MAXIMUM CURRENT 3 A
Single phase transformer speed controllers are designed to manage the rotation speed of electric motors by adjusting the voltage through an autotransformer. These controllers ensure reliable and efficient performance in systems where precise speed regulation is required. The TR1…S series controllers are known for their high quality and additional safety features that enhance the durability of the equipment.
The TR1…S controllers include built-in transformer protection against overheating, ensuring safe and long-lasting operation even under heavy loads. They offer 5 fixed voltage steps, which can be easily switched using a rotary knob, making the controllers simple and convenient to use. Additionally, they provide the option to connect motor thermal contacts (TK) for extra protection, preventing motor overheating.
These controllers can manage multiple motors simultaneously, provided the total current of all connected motors does not exceed the controller's maximum current limit. In such cases, all motor thermal protections must be connected in series to ensure proper safety and functionality.
Features:
- Control: 5 fixed voltage steps
- Output Voltage Levels: 0-115-135-155-180-230V
- Frequency: 50/60 Hz
- Current Range: 0.6 A to 3 A
- Indicator: LED
- Maximum ambient temperature: 35°C
These controllers are ideal for use in various ventilation, cooling, and other systems that require reliable motor speed control. Thanks to their easy installation, user-friendly operation, and built-in safety features, the
TR1…S series transformer speed controllers are an excellent choice for both commercial and industrial applications.
