## Overview

The DollaTek DPS3012 is a versatile step-down power supply module that offers adjustable output voltage up to 30V and current up to 12A. With its precise control, integrated LCD display, and a blend of digital and analog functionalities, this power supply is designed for professionals seeking reliability and accuracy in their projects.

## Description

Description: Its adjustable output voltage range is 0-30.00V, step by step of 0.01V. Its adjustable output current range is 0-12.00A, stepping 0.01A. This module has a stored standby function and can store a preset value of 10 groups. And it also has the function of quickly extracting the stored value of two groups. Compared with traditional analog power supply, it is more convenient to quickly extract the required voltage or current. The LCD on the module has digital voltmeter and ammeter function. You can display preset voltage, input voltage, output voltage, preset current, output current, output power, etc. In the output state reminder area, you can see whether the output opens or not, the voltage is constant and the current is constant, whether the output is normal or not, whether the key is locked or not, and the current data groups are used. On the setting data interface, you can adjust the overvoltage value, overcurrent value, overpower value, dataset and brightness of the LCD screen. Features: Display: 1.44" """ Colorful LCD Input voltage: DC 6-60V. Output voltage: 0-32.00 V. Output Current: 0-12.00A Output power: 0-384W Voltage resolution: 0.01V. Current resolution: 0.01A IN+: Positive input IN-: Negative input OUT +: positive output OUT-: negative output Connection wire length: 200 mm Display module size: 80 x 42 x 45 mm/3.1 x 1.7 x 1.8 inches. Power module size: 91 x 67 x 40 mm/3.58 x 2.64 x 1.57 inches. Weight: approx. 257 g/9.1 oz. Package includes: 1 x Step-Down Module (DPS3012)

## Features

- Its adjustable output voltage range is 0-30.00V, step by 0.01V. Its adjustable output current range is 0-12.000A, step by 0.001A
- Compared with the traditional analog power supply, it is more convenient to quickly extract the voltage or current required
- The constant voltage and constant current programmable control power supply module put the collection of analog integration and digital control functions in one
- LCD display on the module has the function digital voltmeter and ammeter. You can view the preset voltage, input voltage, output voltage, the preset current, output current, output power, etc
- 【Note】1. It must be ensured that the input supply voltage is 1.1 times or more of the output voltage. At high currents, please pay attention to enhance heat dissipation.2.When connecting the display module to the power module, the connection line of the corresponding character should be correctly connected. If the connection is reversed, it will not work properly.
