CDE300 series Conway frequency converter is a frequency converter manufactured by Conway Group's subsidiary (Shenzhen Conway Control Technology Development Co., Ltd.). G3 G5 series Convo frequency converters are made by bosch rexroth Company. In fact, the performance of Convo inverter of CDE300 is not much different from that of G5 inverter, but the interface mode is opposite. In terms of price, the Cornwall inverter of G3 G5 is more expensive than the domestic Cornwall inverter of CDE300 because of bosch rexroth brand. In terms of cost performance, it should be CDE300, which is more cost-effective. I forgot that their English trademarks are different. The logo of bosch rexroth Kangwo is (Kangwo), and the logo of Shenzhen Kangwo Control Technology Development Co., Ltd. is (CANWORLD).
