VONSCH has long been aware of the fact that the majority of converter applications are simple, not taking the advantage of various hardware and software advanced features offered, making the purchase aimlessly expensive. Therefore, VONSCH has developed special converter solution for not high-demanding applications. An innovation of cost effective solution has resulted in E (Economy) series of maximally reliable and quality frequency converters fulfilling customer’s requirements at an unbeatable price. VQFREM 400 E and VQFREM 230 E frequency converter series have been designed to modify successful VQFREM 400 M series into economic version with fewer features. VQFREM 400 E/ 230 E frequency converter series basically do not include RS 485/ 232 interface, do not include braking module, vector control is not supported. User interface has been reduced to simple LED display and a three-button keypad. VQFREM 400 E / 230E primary benefits from its features:
          competitive utilization features at favourable quality-to-price ratio
