AUMA is now producing the SAC actuator in a variable speed version with an onboard inverter.

This inverter allows starting and speed regulation of the actuator without the problem of ‘locked rotor current’, which is fundamental for direct on line motors. The only current drawn is the nominal current, which is much lower.

The benefits of this inverter drive technology are twofold. Firstly, the actuator may be driven from solar panels and batteries by using a readily available power supply or UPS (uninterruptible power supply). This makes it suitable for remote areas, irrigation canals, dams, rivers and critical services.

Secondly, the actuator AC controller may be programmed to have a variety of speeds during travel. This is useful for water transmission pipelines where energy control and water hammer avoidance is necessary.

Additionally, the actuator may be supplied to the highest water level integrity. Standard products are IP68 to 6 m submersion, but an optional AUMA version can be supplied for permanent submersion (like a submarine).

If a corrosive environment is encountered, the already durable KS double powder coating may be augmented by an overpaint such as the Dulux Ferreko EK3, for example.
