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. The device provides voltage and current regulation, features an easy-to-read IPS screen, a number of protections, and the ability to power from various sources - from classic DC power supplies to power banks with Power Delivery function. Thanks to its varied operating modes and support for computer control, it will be suitable for both service and amateur and educational applications.

Efficient cooling and stable operation

The power supply uses high-grade thermally conductive silicon with a thermal conductivity coefficient of 3.0 W/m-K, ensuring efficient heat dissipation from power components. The aluminum chassis acts as a passive heat sink to maintain stable performance even under prolonged operation and heavy load. The FNIRSI DPS150 has a complete set of protections that protect both the power supply and connected devices, including overvoltage, overload, short circuit, overheating, and input/output voltage reversal.

Convenient operation

The built-in 2.8-inch color IPS screen offers high resolution (320x240 px) and 90° rotation for convenient use. The display shows voltage, current, power, temperature, and energy counters in real time. Users can switch between graphical modes and classic numerical view. The DPS150 allows saving up to 6 preset profiles of voltage and current settings for quick switching between operating modes.

High precision

The power supply is characterized by very low noise - ripple below 20 mV, crucial for powering audio, microprocessor, or sensitive sensor circuits. Thanks to digital regulation and built-in control system, voltage and current parameters are very stable and accurate.

Universal connection and various power supply methods

The power supply's outputs support cables with 4mm banana plug terminals, U-type fork terminals, and classic copper wires. Robust metal screw sockets guarantee secure contact and low transition resistance. The device can be powered from a classic DC 5-32V power supply, or via a USB-C connector with PD or QC, allowing use without access to a power grid.
