SMPS – Switched Mode Power Supply for RO, PC & Electronic Devices
Looking to buy a reliable SMPS for your RO system, computer, or industrial device? At Romegamart, we offer a wide range of SMPS power supply units designed for efficient voltage regulation, durability, and safety. Whether you're a home user or a bulk buyer, our SMPS products are priced competitively and sourced from trusted brands to ensure maximum satisfaction.
What is SMPS? (SMPS Full Form)
SMPS full form is Switched Mode Power Supply. It is an electronic circuit that converts AC (Alternating Current) into regulated DC (Direct Current) by switching at high frequency. Unlike traditional linear power supplies, SMPS are more compact, energy-efficient, and generate less heat. They are widely used in RO water purifiers, PCs, LED systems, and automation panels.
SMPS Price in India
The SMPS price in India varies based on type, power capacity, and brand. Here's a general idea:
-
Basic RO SMPS (24V, 2–4 Amp): ₹150 – ₹500
-
High Output SMPS (for 300 GPD RO pumps): ₹500 – ₹1200
-
PC and Industrial SMPS (36V+): ₹1000 – ₹2500
Romegamart offers both retail and wholesale pricing to serve consumers, technicians, and industrial buyers alike.
