KE330 Open Structure Inverter to meet the rapid development of market especially the demands of OEM customers, MICNO launched the new model "KE330 open structure frequency inverter", which equipped with the same function and performance as KE300 or KE600, only the structure design is changed into open structure instead of a close one. As its structure is open, this inverter does not qualify any waterproof and dustproof ability, which must be installed inside an electronic cabinet.
The KE330 open structure inverter consists of two parts: the movement and the radiator.
Mainly targeted at the supporting market applications and OEM customers.
