Overview

The Hammond Power 2909B16 is a 2-coil autotransformer from the 2A-series, designed for industrial motor starting applications. This unit operates at 240V and is rated for up to 1600 HP, providing substantial capacity for large motor loads. Its primary function is to reduce the high inrush current experienced during motor startup. By lowering the voltage supplied to the motor during the starting phase, it significantly decreases the electrical stress on the motor windings, power supply, and associated switchgear. This reduction in starting current helps to prevent voltage sags, protects equipment from premature wear, and extends the operational lifespan of the motor. Manufactured by Hammond Power, a recognized name in electrical power solutions, the 2909B16 is built for reliability in demanding industrial settings. Its robust construction ensures consistent performance, making it a suitable choice for facilities requiring dependable motor control and protection. The autotransformer design offers an efficient method for motor starting without the need for separate starting windings or complex control circuits. The SKU for this model is 2909B16, and it is manufactured in the USA. Its UNSPSC code is 39121035.

Motor Starting Autotransformers 3A-series, 3 Coil, 240V, 1600 HP
The softstarter PSR12-600-70 has a rated maximum operational current of 12 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 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.
