Temperature based 5-step speed controller - 7,5 A - Cooling
Product description
The GTT-1 transformer fan speed controllers control the speed of single phase voltage regulated motors by altering the output voltage in response to temperature.
They have auto-transformers and can manage the fan speed in either automatic or manual mode. Automatic mode has a cooling control function and allows you to manage the speed in five levels based on the integrated flying lead temperature sensor. In manual mode, the integrated control switch may be used to pick one of the specified fan speed positions. This control switch has seven settings: OFF - Automatic mode - Manual mode has 5 speed settings.
Plastic enclosures are available for controllers up to 7,5 A, while metal enclosures are available for versions over 7,5 A.
The enclosure is intended for surface installation inside (IP54). Voltage taps range from 0-(80)-110-140-170-190-230 VAC.
Additional specifications and description
The GTT series of transformer fan speed controllers are a versatile solution for temperature-based motor speed regulation, offering both automatic and manual control options to meet various user requirements.
Temperature-based control
These controllers use an integrated flying lead sensor to measure temperature, enabling them to determine the appropriate motor speed in automatic mode.
Automatic and manual control modes
They provide users with the flexibility of automatic and manual operation. In automatic mode, the controller adjusts the motor speed based on the measured temperature, while in manual mode users can choose from five predefined motor speed levels using the built-in potentiometer on the enclosure.
Stepped control
The controllers offer five distinct speed levels, allowing users to select the desired speed level based on their cooling needs. When auto mode is selected, the controller automatically switches between output voltage levels based on the measured temperature. This flexibility is valuable in environments like industrial facilities, warehouses, grow rooms, glass houses, where precise ventilation control is essential.
Immediate use
These controllers can be used immediately after installation, saving time and effort for users who want to start utilizing fan speed control right away.
Customizable output voltages (option)
Users have the option to customize the five output voltages by changing the internal wiring. While the factory-connected output voltages are 110, 140, 170, 190, and 230 VAC, the product version features 80 VAC, which can be connected by disconnecting any of the other five steps.
Applications
The GTT series of transformer fan speed controllers find applications in various settings where precise temperature control and motor speed regulation are important. They can be employed in heating, ventilation, and air conditioning systems to regulate fan or blower speeds based on temperature changes, ensuring consistent indoor temperatures. In industrial settings, these controllers are suitable for controlling fan speeds in equipment or processes requiring temperature control, such as electronics manufacturing and chemical processes. They are also essential for controlling temperature and airflow in environments like greenhouses, grow rooms, and mushroom fruiting chambers, facilitating optimal conditions for plant growth. Moreover, these controllers automatically eliminate heat, moisture, odor, and dust from enclosures, rooms,
sheds, and similar structures.
Installation
When installing the fan speed controller, it is important to ensure that it can cool effectively. Ideally, it should be placed in a cool location, avoiding direct sunlight.
Surface mountable enclosure
The fan speed controller's housing is designed and manufactured in-house using high-quality r-ABS VO (UL94) plastic. This material possesses desirable properties for this application, including flame-extinguishing properties, which enhance safety in industrial environments where fire hazards are a concern. Its toughness and impact resistance make it well-suited to protect the internal components of the controller from accidental damage or rough handling.
IP54 protection rating
The enclosure provides an IP54 protection rating, offering a good level of defense against both dust and water ingress. This protection is particularly crucial in industrial 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 exposure to dust and water may occur.
