Temperature based 5-step speed controller - 5 A - Cooling
Product description
The GTT-1 transformer fan speed controller regulates the speed of single-phase voltage-controlled motors by varying the output voltage according to the measured temperature.
It is equipped with an automatic transformer and controls the fan speed in automatic or manual mode. In automatic mode, it has a control algorithm for cooling and can control the speed in five steps according to the measured values of the integrated flying lead temperature sensor. In manual mode, the integrated control switch allows the user to select one of the specified fan speed positions. This control switch has seven positions: off - automatic mode - five speed selections in manual mode.
Controllers up to 7.5 A are supplied with a plastic housing, models above 7.5 A are supplied with a metal housing. The enclosures are designed for indoor surface mounting (IP54).
Voltage taps 0-(80)-110-140-170-190-230 VAC. The supply voltage is 230 VAC
Additional specifications and description
GTT series of transformer fan speed controllers provide a versatile solution for temperature-based motor speed regulation in a range of settings, offering both automatic and manual control options to suit different user requirements.
Temperature-based control
These controllers use the temperature measurement from the integrated flying lead sensor to determine the appropriate motor speed in automatic mode.
Automatic and manual modes
The controllers offer both automatic and manual modes of operation. In automatic mode, the controller adjusts the motor speed based on the measured temperature. In manual mode, users can select from five predefined motor speed levels using the built-in potentiometer on the enclosure.
Step control
The controllers provide five steps or speed levels for control. Users can choose the desired speed level based on the cooling requirements of the environment. When auto mode is selected the controller automatically switches between the output voltage levels based on the measured temperature.
By offering five distinct speed settings, the controller allows users to increase the fan speed gradually or set it to the desired level directly. This flexibility can be beneficial in industrial environments, warehouses, where precise control over ventilation is necessary.
Additionally, the fact that the controller can be used immediately upon connection makes it convenient for installation and use. This saves time and effort, allowing users to start utilizing the fan speed control right away.
What is more, you can easily change the 5 output voltages by changing the internal wiring. The factory connected output voltages are 110, 140, 170, 190 and 230 VAC, however, the product version features 80 VAC, which can be connected by disconnecting any of the other 5 steps.
Applications
The GTT series of transformer fan speed controllers can be used in various applications where precise temperature control and motor speed regulation are essential.
These controllers can be used in heating, ventilation, and air conditioning systems to regulate the speed of fans or blowers based on temperature changes, helping maintain consistent indoor temperatures. In industrial settings, these controllers can be employed to control the speed of fans in equipment or processes that require temperature control, such as electronics manufacturing or chemical processes. Controlling the temperature and airflow in greenhouses, grow rooms, mushroom fruiting chambers and is crucial for plant growth. These controllers can help maintain optimal conditions. The controller will automatically eliminate heat, moisture, odor, and dust from enclosures, rooms, sheds and suchlike buildings.
Installation
Make sure that the fan speed controller can cool sufficiently. Preferably install it in a cool place, best not in direct sunlight.
Surface mounted enclosure
The housing of this fan speed controller is designed and manufactured in-house using high-quality r-ABS VO (UL94) plastic, which possesses several desirable properties for this application. The flame-extinguishing nature of r-ABS VO plastic ensures an added level of safety, which is crucial in industrial environments where fire hazards may be present. Its toughness and impact resistance make it well-suited for protecting the internal components of the controller from accidental damage or rough handling.
The IP54 protection rating provided by the enclosure offers a good level of defense against both dust and water ingress. This protection is particularly important in settings where airborne particles and moisture can pose risks to electronic devices. With this level of protection, the fan speed controller can operate reliably even in environments where dust and water exposure may occur.
