## Description

A miniaturised, precision programmable DC power supply designed to bring voltage and current control to any workbench. It condenses the functionality of a traditional heavy benchtop unit into a chassis smaller than a smartphone, capable of delivering up to 150W of power (30V/5A). By utilising modern USB-C Power Delivery (PD) and Quick Charge (QC) protocols, this unit transforms standard wall chargers and power banks into fully adjustable, regulated power sources for testing, prototyping, and diagnostics.

**Note: Input voltage must exceed output voltage. Standard USB PD ~20V (check your USB PD device). Use the DC Barrel Jack input for voltages beyond PD.**

For makers and field engineers, access to a power supply often means being tethered to a fixed workbench. The DPS-150 solves this mobility challenge by offering a "lab-in-a-pocket" solution that runs off the same USB-C chargers you likely already carry for your laptop or phone. Whether you are debugging a PCB in the field, powering a microcontroller project at a hackathon, or simply saving valuable desk space at home, this unit provides clean, stable power without the bulk of a linear transformer.

Manufactured with a focus on usability and precision, the DPS-150 features a 2.8-inch IPS display that tilts 90 degrees for optimal viewing angles, regardless of your setup. It offers exceptional readback accuracy (down to 1mV/1mA) and integrates seamlessly with PC software for automated control and waveform analysis.

### Features

- **Universal Power Compatibility:** Eliminate the need for proprietary power bricks by using standard USB-C PD/QC chargers, power banks, or DC barrel adapters (5V-32V) as your input source.
- **Precise Control & Monitoring:** Safely power sensitive electronics with adjustable output from 0-30V and 0-5A, featuring 1mV/1mA resolution and low ripple noise.
- **Advanced Visual Diagnostics:** Diagnose transient faults and monitor stability using the integrated real-time waveform display, which graphs voltage and current over time directly on the screen.
- **PC Integration & Automation:** streamline complex testing sequences by connecting to a computer via USB to control parameters, log data, and upgrade firmware using the official FNIRSI software.
- **Ergonomic Field Design:** View critical data comfortably from any angle with a 2.8-inch IPS colour screen that physically flips 90 degrees, adapting to crowded or makeshift work surfaces.
- **Comprehensive Circuit Protection:** Protect your projects and the power supply itself with built-in safeguards against Over-Voltage (OVP), Over-Current (OCP), Over-Temperature (OTP), and reverse polarity.

**⚠ Precautions**

- The product operates in step-down mode, so ensure that the input voltage is higher than the output voltage
- The power supply range for this product is Dc 5V~30v. Output will be disabled if the input voltage is lower than 5.0V due to undervoltage lockout, and the device may be damaged if the input voltage exceeds 30V. lt is recommended to use a power supply ranging from 5V to 30V.
- When supplying power to inductive and capacitive loads, it is recommended to connect the load before turning on the device output.
- When outputting high power, some heat generation is normal. lt is recommended to use the device in a well-ventilated environment.
- Please remember not to connect power to both power ports of the device simultaneously, as simultaneous power supply may potentially damage the input source with lower voltage.
- When charging batteries, it is strongly recommended to add a reverse current protection module (such as a Schottky diode) to the output end to protect the device from damage.
