DC Power Supply Explained: Types, Uses, and How to Choose One
A DC power supply is the foundation of any electronics lab or test bench. This guide breaks down every type, what the specs actually mean, and how to choose the right one.

About DC Regulated Power Supplies
CIE Instruments supplies the complete Vartech DC regulated power supply range - from classic transformer-based linear supplies (3005 B, 3010, 3020, 6005, 6010) and dual/multi-output linear units (3005-3 D2, 3005-4, 3010-2, 6005-2) to slim SMPS models (3005 S, 3010 S, 6005 S, 3010 S-2), high-power SMPS with PC interface (SR series: 3020 SR through 20010 SR, up to 2000 W), programmable SMPS supplies (PPS-S series: 7 models, 30–100 V, with USB ModBus-RTU), and the auto-ranging PPSA-100W-8005 S.
Linear power supplies offer the lowest ripple and noise, making them ideal for sensitive analog, RF and precision measurement applications. SMPS-based models trade slightly higher ripple for dramatically reduced weight and heat - the slim S series units weigh just ~1 kg. The SR series adds USB/RS232/RS485 PC interface and ModBus-RTU protocol for automated test and ATE integration. The programmable PPS-S series adds list mode, 6 memories, a rotary dial and display of watts for complete bench automation. Available through CIE Instruments with pan-India supply.
Cambridge Instruments & Engg. Co. (CIE) - manufacturer of precision electrical test and measurement instruments in Howrah, West Bengal, India, established 1963. Pan-India supply: Kolkata · Howrah · Bhubaneswar · Cuttack · Bangalore · Chennai · Hyderabad · Mumbai · Pune · Delhi · Ahmedabad · Lucknow · Chandigarh · Ranchi · Raipur · Visakhapatnam · Nagpur.

Find the right power supply
Tell us the voltage and current your equipment needs. We check all 37 Vartech models and show the ones that fit, closest fit first.
Tip: choose a model with about 20% spare voltage and current over your load, so it is not running at its limit. Ratings shown are the maximum output of the main variable channel. Check the full specification page before ordering.
