Temperature based 5-step speed controller - 12 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.
Equipped with an automatic transformer, it controls the fan speed in automatic or manual mode. In automatic mode, the control function for cooling is provided and the speed can be controlled in five steps according to the measured values of the built-in 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.
Additional specifications and description
The GTT series of transformer fan speed controllers are versatile, easy-to-use and reliable devices designed for temperature-based motor speed regulation.
Temperature-based control
These controllers use an integrated flying lead sensor to measure temperature and adjust the motor speed accordingly in automatic mode.
Automatic and manual modes
They offer both automatic and manual modes of operation. In automatic mode, the controller dynamically adjusts the motor speed based on the measured temperature, while in manual mode, users can select from five predefined motor speed levels using the built-in potentiometer.
Simple 5-step manual fan speed control
Transformer-based fan speed control is a straightforward solution for controlling ventilation in industrial environments. This 5-step fan speed controller provides a convenient way to regulate fans without the need for complex configuration or programming. It offers a quick and efficient method for adjusting the fan speed according to the specific requirements of the environment.
By offering five distinct speed settings, the controller allows users to increase the fan speed gradually or set it to the desired level directly. What is more, 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. Optionally, 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.
Control in steps
The controllers provide distinct speed settings, allowing users to control fan speed gradually or set it to the desired level directly. This flexibility is useful for environments like industrial settings, agricultural premises, warehouses where precise ventilation control is necessary.
Easy installation
These controllers can be used immediately upon connection, saving time and effort during installation.
Customizable output voltages
The controllers come factory connected with specific output voltages but can be easily customized by changing the internal wiring. This allows for greater flexibility in voltage selection, catering to different requirements.
Applications
The GTT series is suitable for various applications, including heating, ventilation, and air conditioning systems, industrial processes, and agricultural settings like glass houses and grow rooms where precise temperature and motor speed control are essential.
Installation guidelines
Installation should be in a cool place, away from direct sunlight, to ensure effective cooling of the controller.
Surface mount enclosure
Enclosures play an important role in protecting the interior components or contents from various external factors such as debris, dust, water, and mechanical impact. The quality of enclosures is indeed essential to ensure the integrity and safety of the enclosed items.
The series features sheet steel enclosures designed to be resistant to external mechanical impacts. They can withstand accidental bumps, collisions, or other physical forces without compromising their structure or the items inside. This feature is particularly important in environments where there is a higher risk of such impacts, ensuring the protection of the enclosed components. The enclosures have a paint finish, which not only provides an aesthetic appeal but also serves as an extra layer of protection against corrosion and other environmental factors. The paint finish helps to enhance the durability and longevity of the enclosure. The EN 62208 certification ensures that the enclosures comply with the standards set for empty enclosures for low-voltage switchgear and control gear assemblies. The ingress protection rating of IP54 guarantees that the enclosures are designed to provide a high level of protection against dust and water ingress, they are effectively sealed against dust particles and can withstand water splashes from any direction, making them suitable for moderately harsh environments.
