FNIRSI DPS150 DC Programmable Mini Laboratory Power Supply

FNIRSI DPS150 DC Programmable Mini Laboratory Power Supply

The FNIRSI DPS150 is a compact, programmable laboratory power supply that combines high functionality with a portable form factor. It provides precise voltage and current regulation, features a clear 2.8-inch IPS color screen, multiple protection mechanisms, and supports powering from various sources including traditional DC power supplies and power banks with Power Delivery (PD) functionality. Its versatile operating modes and computer control compatibility make it suitable for professional service, amateur, and educational applications.

Efficient Cooling and Stable Operation

This power supply utilizes high-grade thermally conductive silicon with a thermal conductivity coefficient of 3.0 W/m-K to ensure effective heat dissipation from power components. The aluminum chassis serves as a passive heat sink, maintaining stable performance during prolonged use and under heavy loads. Comprehensive protections include overvoltage, overload, short circuit, overheating, and input/output voltage reversal safeguards to protect both the device and connected equipment.

Convenient Operation

The built-in 2.8-inch color IPS display offers a high resolution of 320x240 pixels and supports 90° rotation for flexible viewing. The screen displays real-time voltage, current, power, temperature, and energy counters. Users can toggle between graphical and classic numerical display modes. The DPS150 allows saving up to six preset profiles of voltage and current settings for quick switching between different operating modes.

High Precision

Characterized by very low noise with ripple below 20 mV, the power supply is ideal for powering sensitive audio, microprocessor, or sensor circuits. Digital regulation and an integrated control system ensure highly stable and accurate voltage and current output parameters.

Universal Connection and Multiple Power Supply Options

The output terminals support cables with 4 mm banana plugs, U-type fork terminals, and traditional copper wires. Robust metal screw sockets provide secure contact and low transition resistance. The device can be powered from a classic DC source ranging from 5 V to 32 V or via a USB-C connector supporting Power Delivery (PD) or Quick Charge (QC), enabling operation without direct access to mains power.
