iStart AC Motor Soft-Starter

iStart is an electronic single phase AC motor soft-starter designed for Permanent Split Capacitor (PSC) motors of up to 4.5kW (6HP) output. These motors are typically used in appplications such as air conditioning and refrigeration compressor motors, condensing units and air curtains.

Its primary purpose is to reduce the current drawn by the PSC motor at start-up to below 45 Amps. This is a regulatory requirement in Australia, and being enforced by energy suppliers to reduce excessive loads on power supply. It is also becoming adopted as a 'best practice' by air conditioning system suppliers and installation contractors, as well as electricians, in order to reduce motor wear and tear, particularly in areas with poor quality of supply, especially where varying voltages and under-voltage issues may cause damage to attached devices.

Using iStart results in lower power consumption at start-up, reduced acoustic noise and significantly less ‘light flicker’ when the motor starts. It also features ‘under-voltage’ protection, which disables the attached motor in the event of mains power outages, power ‘brown-outs’, or hardware failure. 

The overall result is superior motor protection, greater reliability and extended motor life, all at a very low price. And with iStart having proved itself extraordinarily reliable in the field, it represents excellent value for money in a range of applications, including those in remote areas, or where 'high availability of service' levels are essential. But given it's from a company with more than two decades's of experience and a history of supplying hundreds of thousands of electronic control devices into a range of industrial, commercial and consumer applications, you wouldn't expect any less.

Note:
 iStart can also be supplied in an OEM format (without a housing, and
   with or without the capacitor) for compressor or fan motor suppliers
   wanting to incorporate an efficient, reliable soft starter into their own
   product.
