FNIRSI DPS-150 Mini DC Adjustable CNC Programmable Regulated Switching Power Supply

The FNIRSI DPS150 is a compact, programmable laboratory power supply that combines high functionality with a mobile form factor. The device provides voltage and current regulation, has an easy-to-read IPS screen, numerous protections and the ability to be powered from different sources - from classic DC power supplies to power banks with the Power Delivery function. With different operating modes and support for PC control, it will be suitable for both service and amateur and educational applications.
The power supply uses high-quality thermally conductive silicon with a thermal conductivity coefficient of 3.0 W/m-K, which ensures efficient heat dissipation from the power components. The aluminum housing acts as a passive heatsink, so it provides stable performance even during longer operation and heavy load. The FNIRSI DPS150 has comprehensive safety features that protect both the power supply and connected devices. The device offers the following, among others. protection against overvoltage (OVP), overload (OCP), short circuit (SCP), overheating (OTP), and input and output voltage reversal.
The built-in 2.8-inch color IPS screen offers high resolution (320×240 px) and 90° rotatability for comfortable use. The display shows voltage, current, power, temperature and energy counters in real time. Depending on the user's preferences, he can switch between graphic modes and the classic numerical view. The DPS150 allows the user to save up to 6 preset voltage and current setting profiles. This allows for immediate switching between operating modes, which significantly speeds up the testing of different circuits or components.
The 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 the digital regulation and built-in control system, the voltage and current parameters are very stable and accurate.
The outputs of the power supply support cables with 4 mm banana plug connectors, U-type plug connectors and classic copper conductors. Robust metal screw sockets guarantee secure contact and low transient resistance, which means accuracy and safe operation. The device can be powered either from a classic 5-32 V DC power supply or via a USB-C connector with PD/QC function, such as a power bank or laptop charger. This allows the DPS150 to be used without access to the mains, increasing its use during service or field work.
