AutomationDirect: Full-Featured Soft Starters

Stellar soft starters now includes the SR55 series of solid-state soft starters to control three-phase AC induction motors.

Designed to withstand up to 477 FLA (at 200-480 VAC), the starters are available in three frame sizes, are fully digital, provide full motor overload protection, and use thyristors in all three motor phases for controlled, reduced voltage motor starting and stopping. They are used in general purpose soft start motor control applications where traditional across-the-line starting or wye-delta starting would typically be appropriate and are ideal in applications requiring lower inrush currents. The units also have a built-in internal bypass and patented iERS (intelligent Energy Recovery System) that reduces energy costs when used on lightly loaded and oversized motors. Features include 24 VDC, 110 or 230 VAC selectable control voltage, as well as easily and separately adjustable motor start and stop times. The fully programmable units are equipped with a touchscreen with an easy-to-navigate menu structure, a quick automatic application setup feature, built-in SCR failure protection, and full data logging (fault records, motor current, operational status, etc). They offer integrated Modbus RTU, or optional Modbus TCP or Ethernet/IP communication, as well as programmable analog I/O, digital inputs and relay outputs for remote control.

Top 10 Indian Embedded Companies

It has been over two years since I wrote the piece — Top 10 embedded companies in India! It has been the most read, and by far, the most commented.  Now, it is time to do a review, or, more suitably, a recap!

First, who are the top 10 (Indian) embedded systems and software companies in India? My list, in no particular order, would read something like this:

1. Ittiam
2. Sasken
3. Sofcon
4. C-DAC
5. L&T EmSyS
6. ProcSys
7. eInfochips
8. Mistral
9. iWave Systems/Global Edge
10. Vayavya Labs

There are several firms in Pune and Hyderabad, who probably deserve a name.  There may be some folks may not agree with this list, but I would go with these, for now. The next change could be two years down the road!

Some may even question the presence of Sofcon System and C-DAC in this list. However, Sofcon has well over 30+ years of extensive experience in providing consulting, design and development services and testing services in real-time systems.

C-DAC has capabilities in high-performance computing as well as grid computing. It also has unit focusing on professional electronics, including embedded and VLSI products.

Ittiam and Sasken remain in the top 5 category. ProcSys is a new entrant, besides iWave, Global Edge and Vayavya Labs.

Now, may I know if you have any doubts, as well as moves, additions and/or changes (MAC)?
