FNIRSI DPS150 DC Programmable Mini Laboratory Power Supply Unit
FNIRSI DPS150 is a compact programmable laboratory power supply designed for precise voltage and current control in electronics testing, servicing, and educational applications. The device features a 2.8-inch IPS color display, low-noise output below 20 mV ripple, and support for multiple power sources including DC input, USB-C Power Delivery, and Quick Charge. Advanced safety protections, preset memory profiles, and stable digital regulation make it suitable for powering sensitive circuits, microcontrollers, audio systems, and laboratory projects. Its portable aluminum housing and efficient cooling system ensure reliable operation during extended use in both workshop and field environments.
The power supply features a 2.8-inch IPS color display with a 320×240 resolution and 90-degree screen rotation for convenient operation in different working positions. Real-time monitoring of voltage, current, power, temperature, and energy consumption allows precise control over connected devices. Users can switch between graphical and numerical display modes depending on preference and workflow requirements. Additionally, the device supports storing up to six programmable voltage and current presets, enabling rapid switching between frequently used configurations.
Advanced digital regulation ensures highly stable output parameters with ripple below 20 mV, making the DPS150 suitable for powering sensitive electronic systems such as microcontrollers, audio equipment, sensors, and development boards. Comprehensive protection systems including overvoltage, overload, short-circuit, overheating, and reverse polarity protection safeguard both the power supply and connected equipment during demanding operation.
