Product Description:

The 135U3275 is a frequency converter that boasts of an enclosure that meets the IP55 protection category and allows for the efficient protection of the internal components of the units, even when it is used in environments that will normally be considered to be too unfavorable for conventional products. This is specifically designed to be used for the control of motors used in water management. It is very flexible in design and will adapt its operation to suit the current motor load. Compared to other converter designs, this product is able to provide an operation efficiency level that falls between 3 to 8 percent. During the operation of this product, it automatically detects faults in the servo system and alerts operators by displaying an error message on its Graphical Local Control Panel (LCP). The warnings and alerts of this product can be adapted according to the preferences of the operator.

The 135U3275 frequency converter contains an internal fan that helps it to maintain permissible internal temperature levels. The operation of these fans is generally determined by the heat sensors; at low load or sleep load, the fans are not running, and energy is significantly conserved. Radio Frequency Interference is a significant problem that affects the electrical circuit of this product; however, there is a built-in filter that is present in this product to reduce high-frequency signals and ensure that the operation of the converter meets international standards.

The 135U3275 frequency converter keeps track of the thermistor installed inside the winding of this product. This monitoring allows it to detect rising temperature levels in the connected motor and raise an alarm before overheating occurs. Temperature levels around this product should be closely watched and maintained below 45 degrees to ensure operation without derating.
