The new frequency converter from ABB is designed for machine applications that require a high level of protection. Because no special enclosures and cabinets are required, the closed design speeds installation, saves money, and gets the drives into operation quickly. The ACS350 General Machinery Drive – with UL Type 4X (IP66) protection – is offered in a 0.5 to 10 Hp (0.37 to 7.5 kw) range.
"This high level of protection is suitable for indoor applications, such as screw conveyors, mixers, pumps, fans and lifts that are used in places where the machines operate in a load of dust, moisture, high-pressure washing and cleaning chemicals," said Kathleen Watson, the product manager for the series. "These applications typically occur in, but are not limited to, the food & beverage, textile, ceramics, pulp and paper industry and water / wastewater industries," she noted.
Thrives in Wash-down and High-dust Environments
The design and materials used in the drive’s construction comply with current National Sanitary Foundation (NSF) standards. The drive’s sleek design does not provide any nesting places for bacterial, and all components are protected from ingress of water. The control panel is designed for use in humid environments, and is protected against infiltration of dust by a plastic window; the fan is integrated into the housing of the unit. This design does not have an external fan, which reduces the chance for failure in harsh environments.
