Buck Converter Dual Display 3A DC-DC 5-23V To 0-16.5V Step Down Power Supply Buck Converter Adjustable LCD Step- down Voltage Regulator With Case

This is the 23V variant of the Buck Converter Dual Display 3A DC-DC 5-23V To 0-16.5V Step Down Power Supply Buck Converter Adjustable LCD Step- down Voltage Regulator With Case in Buck Converter. Available at ₹575.99 (₹488.13 + GST) with free shipping across India.

The Dual Display 3A DC-DC 5-23V to 0-16.5V Step-Down Power Supply Buck Converter Adjustable LCD Step-Down Voltage Regulator is a versatile digital voltage regulator module equipped with an STC LCD screen. It displays both the output voltage and current simultaneously for easy monitoring. The module also features reverse protection for added safety. Unlike traditional potentiometers, it uses an onboard tactile push button to adjust the output voltage, offering more precise control.

Additionally, the module comes with an outer shell for enhanced durability and protection, transforming into a portable digital voltmeter once assembled.

Working Parameters:

• Input Voltage: 5-23V
• Output Voltage: 0.01-18V (continuously adjustable), with the module automatically saving the last set voltage (input voltage must be at least 1V higher than the output voltage).
• Output Current: Maximum 3A (recommended usage within 2A; if heat is excessive, additional heat dissipation measures may be required).

Note: The current adjusts automatically based on the load and is not user-adjustable.

Buck Converter Dual Display 3A DC-DC 5-23V To 0-16.5V Step Overview

The Buck Converter Dual Display 3A DC-DC module is a compact adjustable step-down power regulator that converts 5–23 V input into a precise 0–16.5 V output. With dual LCD readouts for voltage and current, it’s ideal for laboratory benches, DIY electronics and on-the-go power adjustment.

Key Features of Buck Converter Dual Display 3A DC-DC 5-23V To 0-16.5V Step

• Wide input range: 5–23 V DC, supports most adapters, batteries and solar panels
• Adjustable output: 0.01–16.5 V with 0.01 V resolution and 1% display accuracy
• Maximum 3 A output current (use heatsink for sustained >2 A loads)
• Onboard push-button control for precise voltage setting; remembers last voltage on restart
• Built-in reverse polarity protection and high-efficiency design (up to 95%)
• Durable plastic case transforms into portable digital voltmeter after assembly
• Genuine product, fast shipping from Zbotic.in across India

Applications and Use Cases

• Laboratory bench power supply for microcontroller and sensor testing
• Custom voltage source for LED strip dimming or spotlight experiments
• Power regulation for automotive 12 V systems to 5 V or 3.3 V accessories
• Portable field tool: assemble in its case to monitor battery or panel output
• Constant-voltage charging of small NiMH or LiPo battery packs

How to Use Buck Converter Dual Display 3A DC-DC 5-23V To 0-16.5V Step

Connect the input terminals to your 5–23 V supply (observe correct polarity), then hook the load to the output terminals. Power on and short-press the onboard button to enter voltage adjustment, using further presses to set digits. The dual LCD displays real-time output voltage and current. For currents above 2 A, attach a heatsink to maintain thermal stability.

Frequently Asked Questions

What is the minimum input-output voltage difference?

This module requires at least a 1 V difference between the input and output voltages to regulate properly (for example, 12 V in to 11 V out).

Can I run a 3 A load continuously?

Short-term peaks up to 3 A are supported, but for continuous currents above 2 A you should install an additional heatsink to prevent overheating.

How do I set and save the output voltage?

Short-press the tactile button to enter adjustment mode, use repeated presses to select and change each digit, then wait three seconds without pressing to confirm and save the setting automatically.
