15W 2A Adjustable USB Power Supply Module – DP3DT Switch, Regulated Output (NC)

Description

Product Overview

The DP3DT 15W Adjustable USB Power Supply Module is a high-precision, digitally controlled DC-DC converter that combines step-up and step-down capabilities in a compact, ready-to-use package. This versatile power module serves as a programmable constant voltage/constant current (CV/CC) power supply, allowing you to generate a stable output voltage from 1V to 30V using a standard USB power source .

Unlike traditional power supplies, the DP3DT features a digital encoder knob for precise voltage and current adjustment, eliminating the drift and inaccuracy associated with analog potentiometers. The onboard LCD display provides real-time monitoring of input voltage, output voltage, output current, output power, and capacity statistics .

A standout feature of this module is its intelligent fast charge trigger function. By negotiating with QC2.0/3.0, AFC, FCP, or SCP compatible chargers, it can request higher input voltages (9V or 12V), enabling full 15W output power even when powered from a standard USB power bank or phone charger .

Whether you are a hobbyist building a benchtop power supply, a technician needing an adjustable charger for lithium batteries, or an engineer prototyping circuits, the DP3DT provides a precise, portable, and highly functional power solution.

Key Features

• Digital Encoder Control: Uses a high-resolution digital encoder with push-button selection for precise, drift-free adjustment of voltage and current limit .

• Wide Input & Output Range: Accepts 4V–13V DC input (via USB-A, MicroUSB, or Type-C) and provides 1V–30V DC output, covering a vast range of applications .

• 15W / 2A Power Capacity: Delivers up to 15W of output power with a maximum output current of 2A, suitable for powering a wide variety of devices and charging batteries .

• Constant Current (CV/CC) Mode: Features programmable constant current limiting, making it ideal for charging batteries (Li-ion, LiFePO4, Lead-Acid) and driving high-power LEDs without additional circuitry .

• Intelligent Fast Charge Trigger: Automatically negotiates QC2.0/3.0, AFC, FCP, and SCP fast charge protocols with compatible USB chargers to unlock 9V or 12V input for full power operation .

• Comprehensive LCD Display: Monitors input voltage, output voltage, output current, output power, and capacity (mAh) in real-time with a resolution of 0.01V and 0.001A .

• Push-Button Wiring Terminals: Features tool-free, push-button style terminals for fast and secure connection of output wires without needing a screwdriver .

• Multiple Protection Features: Includes Short Circuit Protection (SCP), Over-Current Protection (OCP), Over-Power Protection (OPP), and Over-Temperature Protection (OTP) to safeguard the module and your devices .
