Computer Power Supply

FNIRSI DPS150 DC programmable mini laboratory power supplyThe 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 (In-Plane Switching, a matrix that uses liquid crystals aligned in parallel, thus providing rich and perfectly reproduced colors), a number of protections, and the ability to power from various sources - from classic DC power supplies to powerbanks 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 operationThe power supply uses high-grade thermally conductive silicon with a thermal conductivity coefficient of 3.0 W/m-K, which ensures 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. Among other things, it offers protection against overvoltage (OVP), overload (OCP), short circuit (SCP), overheating (OTP) and input and output voltage reversal.Convenient operationThe built-in 2.8-inch color IPS screen offers high resolution (320×240 px) and 90° rotation for convenient use. The display shows voltage, current, power, temperature and energy counters in real time. Depending on preference, the user can switch between graphical modes and the classic numerical view. The DPS150 allows the user to save up to 6 preset profiles of voltage and current settings. This allows you to instantly switch between operating modes, which significantly speeds up testing of different circuits or components.High precisionThe power supply is characterized by very low noise - ripple below 20 mV. This is crucial when 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 methodsThe 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, which translates into accuracy and safe operation. The device can be powered either from a classic DC 5-32V power supply, or via a USB-C connector with PD (Power Delivery, USB-C fast charging technology) or QC (Quick Charge, a fast charging standard that significantly reduces battery charging time without compromising battery life), such as from a powerbank or laptop charger. This allows the DPS150 to be used without access to a power grid, increasing its use in service or field work.Included cable with crocodile clamp x2 USB cable user manual Manufacturer Fnirsi Model DPS-150 Input voltage DC 5.0 V - 32 V Input current 100 mA - 5 A Resolution Voltage: 10 mV; Current: 1 mA Reading accuracy Input voltage: ≤0.2% ±5 mV; Output voltage: ≤0.1% ±10 mV; Output current: ≤0.1% ±5 mA (for 0-3.5 A range) Operating environment Temperature: 0 °C - 40 °C; Relative humidity: 0% - 75% RH Display 2.8 inches (320×240 pixel resolution) Output Voltage: 0 - 30 V; Current: 0 - 5 A; Power: 0 - 150 W.

It offers adjustable brightness up to 350 lm and the ability to adjust the color temperature in the range of 2700–6000 K. This allows you to easily adjust the lighting to different tasks and times of day! The thoughtful design eliminates screen reflections, and the additional RGB backlighting creates a pleasant atmosphere when watching movies or playing games. You can also synchronize the light with games, movies, or music. The lamp is compatible with the Matter standard and is easy to operate with the included remote control knob.Comfort for your eyes and true-to-life color reproductionThe lamp is designed to reduce eye strain during long periods of computer use. The light falls on the desk at a 45° angle, illuminating the keyboard and workspace while eliminating glare on the monitor. This keeps the image clear and reduces eye strain, even during long hours of work or study. What's more, the light generated by the lamp does not dazzle or flicker. You also don't have to worry about harmful blue light. In addition, Yeelight Libra 2 provides very good color rendering thanks to a CRI of Ra95. Illuminated objects retain their natural colors and clear details, which is especially important when working with graphics, photos, or video materials.Smooth adjustment, RGB backlighting, and synchronization with your screen or musicThe lamp allows you to precisely adjust the lighting to your current needs. Smooth color temperature adjustment in the range from 2700 K to 6000 K allows you to create the right conditions for both evening relaxation and work requiring concentration. You can also adjust the brightness to the conditions in the room at any time. In addition, there is a memory function that allows the device to restore the last settings when it is turned on again. You don't have to adjust everything from scratch every time! But that's not all – the back of the lamp is equipped with RGB ambient lighting, which creates an atmospheric background behind the monitor. You can also synchronize the device with the image on the screen or music so that the light reacts to the game, movie, or songs being played. It's a great way to create a unique atmosphere!Convenient control – wireless knob and Matter compatibilityThe lamp is operated using a wireless control knob that allows you to quickly turn the light on and off, choose from available modes (Office, Relax, Custom), adjust the color temperature, and set the brightness. Everything you need is at your fingertips! In addition, the device is compatible with the Matter standard, so it can work with popular smart home systems such as Apple Home, Google Home, Amazon Alexa, and SmartThings. Control your lighting with an app or voice commands, create automations, and much more!Stable mounting on various monitorsA specially designed mount allows the lamp to be securely attached to various types of monitors – from thin (minimum 10 mm) to thick (up to 50 mm) to curved (R1000-R1800). The 25° tilt adjustment option allows you to direct the light exactly where you need it. In addition, the length of approximately 486 mm makes the Libra 2 suitable for 27-inch screens, and the soft silicone base protects the display from scratches. The lamp is powered by USB-C.
