Overview

The Hammond Power 2909C16 is a 2A-series, 2-coil autotransformer engineered for industrial motor starting applications. Designed for 480V systems, this unit supports motors up to 1600 HP. Its primary function is to significantly reduce the high inrush current experienced during motor startup. By mitigating this surge, the autotransformer helps to prevent excessive voltage drops across the power system, thereby protecting not only the motor itself but also other connected electrical equipment. This reduction in electrical stress contributes to an extended motor lifespan and improved overall system reliability. Manufactured by Hammond Power, a recognized name in power solutions, the 2909C16 is built for dependable operation in demanding industrial settings such as manufacturing plants, mining operations, and water treatment facilities. Its construction emphasizes durability for heavy-duty use. The design also aims for efficient motor starting, which can translate to lower energy consumption during the startup phase. This autotransformer is compatible with standard 480V electrical infrastructure and provides precise voltage regulation, crucial for safeguarding motors and associated machinery. It is an ideal component for applications that require substantial starting torque while minimizing electrical strain on the power grid and motor components.

Motor Starting Autotransformers 3A-series, 3 Coil, 480V, 1600 HP
The softstarter PSR72-600-70 has a rated maximum operational current of 72 A with an operating voltage span from 208...600 V AC. The rated control voltage is between 100...240 V AC at 50/60 Hz. PSR features a two-phase control soft start and stop through a voltage ramp. It has built-in bypass for easy installation and energy saving. A RUN and a TOR signal is available from a relay output in NO (normally open state). The start/stop ramp and time is easy to set by three potentiometers on the front. PSR is often used in combination with a manual motor starter (MMS) from ABB, so mechanical connection kits are available. Another popular option is Fieldbus communication, which can be enabled by an external adaptor and a Fieldbus plug. The PSR range is our most compact softstarters with basic functionality and values. They are suitable for small three-phase motors with nominal currents from 3...105 A and can manage up to 100 starts per hour. Common applications are, for example, pumps, fans, compressors, and conveyors.
