History and Background
Company Foundation
The origin of Electronic Control Product Kolkata traces back to the early 1990s when a group of electrical engineers established an engineering consultancy in central Kolkata. The founders sought to bridge the gap between traditional manufacturing practices and emerging automation technologies. Their initial focus was on custom control solutions for local textile mills and power distribution networks.
Early Years and Product Evolution
In 1996, the firm introduced its first batch of programmable logic controllers (PLCs) tailored to regional manufacturing requirements. These units were based on microcontroller architectures popular in the West but were modified to accommodate local power supply variations and climatic conditions. The success of this venture spurred the development of a broader portfolio, including variable frequency drives (VFDs), motor protection relays, and safety interlock systems.
Brand Consolidation
By 2005, the company formalized its brand identity as “Electronic Control Product Kolkata.” The name reflected both the geographical origin and the core product focus. This rebranding coincided with a strategic shift toward standardization, adoption of IEC standards, and the establishment of a dedicated research and development wing. Subsequent years witnessed a steady expansion of product lines, incorporation of advanced communication protocols, and entry into national and international markets.
