FNIRSI DPS150 DC programmable laboratory power supply

FNIRSI DPS150 DC programmable mini laboratory power supply

FNIRSI DPS150 is a compact, programmable laboratory power supply that combines extensive functionality with a portable design. The device provides voltage and current regulation, a clear IPS display (In-Plane Switching, a matrix that uses parallel liquid crystals to ensure rich and perfectly reproduced colors), a range of safety features, and the ability to power from a variety of sources – from classic DC power supplies to power banks with Power Delivery. Thanks to its diverse operating modes and support for computer control, it is suitable for both service, amateur, and educational applications.

Efficient cooling and stable operation

The power supply uses high-quality thermally conductive silicone with a thermal conductivity coefficient of 3.0 W/m·K, which ensures effective heat dissipation from the power components. The aluminum housing acts as a passive radiator, allowing for stable parameters even during prolonged operation and heavy loads. The FNIRSI DPS150 has a complete set of safeguards that protect both the power supply and connected devices. It offers among others . protection against overvoltage (OVP), overload (OCP), short circuit (SCP), overheating (OTP) and reverse voltage connection at input and output.

Convenient operation

The built-in 2.8-inch color IPS screen offers high resolution (320x240 px) and 90° rotation for comfortable use. The display presents voltage, current, power, temperature, and energy meters in real time. Depending on your preferences, you can switch between graphical modes and a classic numerical view. The DPS150 allows you to save up to 6 preset voltage and current setting profiles. This allows you to instantly switch between operating modes, significantly speeding up the testing of different systems or components.

High precision

The power supply features very low noise—ripple below 20 mV. This is crucial when powering audio systems, microprocessors, and sensitive sensors. Thanks to digital regulation and a built-in control system, voltage and current parameters are very stable and accurate.

Universal connection and various power supply methods

The power supply outputs support cables with 4mm banana plugs, U-type spade terminals, and classic copper wires. Solid metal screw sockets ensure reliable contact and low contact resistance, ensuring accuracy and safe operation. The device can be powered either from a classic 5-32V DC power supply or via a USB-C port with PD (Power Delivery, a fast charging technology via USB-C) or QC (Quick Charge, a fast charging standard that significantly reduces battery charging time without compromising battery durability), for example, from a power bank or laptop charger. This allows the DPS150 to be used without access to a power grid, increasing its usefulness in service or field work.
