The Telemecanique VW3A5305 is a high-performance output dV/dt filter designed to enhance the operation of variable speed drives ranging from 15 to 45kW with a rated current of 95A. This filter is an essential component for industrial applications where it is necessary to mitigate the effects of voltage spikes and electrical noise in motor-driven systems. Its compatibility with the Altivar range, including the Altivar 610, Altivar Process ATV900, Altivar Process ATV600, and Altivar Machine ATV340, makes it a versatile solution for a wide array of setups.
Constructed to maintain efficiency, the VW3A5305 can handle maximum motor cable lengths of up to 500 metres with unshielded cables and 300 metres with shielded cables. It is capable of withstanding dV/dt peaks up to 3000 V/µs, ensuring the longevity and reliability of connected equipment. The filter operates effectively within an ambient air temperature range of -10 to 50°C without current derating, and up to 60°C with a slight derating, making it suitable for challenging environments.
The unit's robust design includes an IP20 degree of protection, which can be upgraded to IP21 with an additional kit, providing flexibility in terms of installation environments. The VW3A5305 is also compliant with environmental regulations, including REACh and EU RoHS, ensuring that it is free from harmful substances such as toxic heavy metals and mercury.
With dimensions of 300mm in width, 610mm in height, and 245mm in depth, and a net weight of 19kg, the filter is designed for easy integration into existing systems. Its thermal losses are minimised, rated at 92W at 4 kHz, contributing to a more energy-efficient operation.
Overall, the Telemecanique VW3A5305 output dV/dt filter is a reliable and environmentally conscious choice for optimising the performance and protection of variable speed drives in industrial applications.
