Prok Devices

What Prok Devices does

Prok Devices Private Limited, founded in 1991 by three engineers in Electrical and Electronics Engineering, is a Bengaluru-headquartered private manufacturer of static and microcontroller-based protection relays and digital meters for power system applications. The company's portfolio spans three categories: 16 relay types (Earth Leakage, Earth Fault, Restricted Earth Fault, Over Current, Motor Protection, Power Factor Controller, Voltage, Line Voltage Monitor, Reverse Power, Phase Failure, Frequency, Neutral Displacement, Differential, Auxiliary, and Master Trip relays), five meter types (Energy Meter, Ammeter, Voltmeter, VAF Meter, Tap Position Indicator), and two control devices (Auto Source Changeover Cum Current Limiter and Battery Chargers/SMPS). Core technology rests on in-house R&D that has migrated the entire product line from static to microcontroller/numerical architecture, with most products featuring RS-485 Modbus communication, IDMT/Definite Time/Instantaneous characteristics, fault recording, and tropicalised design suited to Indian conditions. Products are ISO 9001-2015 certified and type-tested at authorized labs (C.P.R.I, E.T.D.C, L.R.D.E, SAMEER).

Prok Devices generates revenue through B2B hardware sales, project-based panel design services, and an inquiry-driven pricing model with no public list prices. Go-to-market combines a pan-India dealer network, direct enterprise sales via branch offices in major metros, and marketplace listings on IndiaMART and Alibaba for SMB and small-order capture; the company also exports through distribution partners and participates in international exhibitions. Approved-vendor status with Technical Consultants, Electricity Boards, Public Sectors, and OEMs creates a qualification-driven switching cost across enterprise accounts in mining, cement, steel, oil refineries, power generation and distribution, software-industry campuses, commercial high-rise buildings, and educational institutions.

Operations are led by founding Directors H.K. Shivaram (Design, Marketing, Finance), R. Narasingarao (Production, Purchase, Vendor Development), and Mahesh Jain (also founder of SEBI-registered AIF fund Sprout Venture Partners), with next-generation executive Taksh Jain (Applied AI) leading digital transformation and smart-grid automation initiatives. The company received the 2017 Sri M. Visvesvaraya Manufacturing Excellence Award and is privately held with no external institutional capital disclosed. Customer concentration spans heavy-industrial verticals with project-driven order cycles, and 2025 saw launches of Automatic Transfer Switch, Power Pack, Master Trip, and Auxiliary relays alongside scheduled appearances at Middle East Energy Dubai 2026, Elektrotec 2026, and EL Asia 2026, signalling near-term export push.
