AC drive for HVAC

S-Flex enclosed ac drives are said to significantly reduce the cost of providing coordinated motor control for variable torque pump applications.

The drive can be specified as an alternative to an enclosed drive, making it easier to accommodate last-minute project changes, as well as aftermarket retrofits. The drive meets all new requirements for industrial control panels with a 100,000 AIC rating without power fuses. It includes overcurrent and branch circuit protection and has an integrated ac line reactor thermal rated at 150% for harmonic abatement and transient protection.
