Soft start controllers reduce energy costs, increase system life
Eaton DS7 soft start controller is designed to reduce energy costs and increase system life.
Industrial manufacturer Eaton Corporation introduced the DS7 line of soft start controllers designed for customers. The DS7 soft starters reportedly provide smooth acceleration and deceleration of the load, minimizing shock to mechanical components, extending life of the system, increasing reliability, reducing downtime and lowering costs. Designed for pump, fan and conveyor belt applications, as well as water/wastewater and heating, ventilating and air conditioning (HVAC) industries, the DS7 soft starters reduce the demands made on a motor during start up, resulting in reduced energy requirements. 
“By minimizing mechanical and electronic impact on the system, soft starting increases component life,” said Ram Tenneti, product manager, Eaton. “The DS7 soft starter can control motor deceleration, reduce peak in-rush current, minimize penalties from utilities and reduce costs.”
Because of its small size, the Eaton DS7 soft starter can provide customers with the benefits of soft starting without necessitating a change in enclosure sizes or additional assemblies. Additionally, it has an integrated bypass relay.
The DS7 is available for current ranges from 16 to 32 amps. With an asymmetric delay angle control, the DS7 helps make torque behavior similar to a three-phase starter. It can take 24 volts (V) of direct or alternating current, or 110V/230V of alternating control voltage. It is also Underwriters Laboratories (UL) approved.

2012 Salary Survey
In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.
Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
