FNIRSI® DPS-150P 150W Portable DC Power Supply, PD3.1, Microamp Readback

Feature

• 150W Portable Adjustable DC Power Supply: Delivers adjustable output from 0–30V and 0–5A, with a maximum output power of 150W. Supports Constant Voltage (CV) and Constant Current (CC) modes for flexible power control across electronics testing, development, and repair tasks.
• μA-Level Low-Current Readback Accuracy: Supports precise current monitoring across low-current measurement ranges, with readback accuracy of ≤0.2% + 5μA for currents below 500μA and ≤0.2% + 100μA for 500μA to 50mA. This enables closer observation of low-power device consumption, standby behavior, and small current changes during debugging.
• High-Current Readback Accuracy: Provides current readback accuracy of ≤0.1% + 5mA for currents above 50mA, supporting more consistent monitoring of power consumption during higher-current testing and adjustable power supply operation.
• Low-Ripple Output for Stable Power Delivery: Provides ≤10mVpp full-load output ripple, helping reduce unwanted output fluctuations when powering sensitive electronic circuits and supporting more stable power delivery during development and debugging.
• PD3.1, QC & DC Multi-Input Power Supply: Supports PD3.1, QC, and DC input power options. The DC input range is 5.0–32V, while the recommended input voltage is 5–30V. Compatible power banks meeting the required input specifications can also be used for portable operation.
• Programmable Sequence Output: Supports sequential output based on configured voltage, current, sequence numbers, and loop counts. Users can pause the sequence while maintaining the current step, continue the sequence after a delay, or perform manual single-step testing for controlled power test workflows.
• Voltage & Current Sweep Testing: Provides programmable voltage sweep and current sweep functions. Voltage sweep operates with a fixed current, while current sweep operates with a fixed voltage. Adjustable step sizes and delay times support systematic testing of electronic devices and power response characteristics.
• PC Software Monitoring & Output Control: Connects to a computer through the Micro data transfer interface for device monitoring and output control. The PC software supports input voltage, output voltage, current, power, temperature, and status monitoring, as well as output settings and preset management.
• Voltage & Current Waveform Recording: Supports recording, saving, deleting, and reviewing voltage and current waveform data through PC software. Single waveform views can be zoomed using the mouse scroll wheel, helping users inspect measurement trends and recorded data.
• 2.8-Inch IPS Color Display with 90° Flip Design: Features a 2.8-inch, 320 × 240 display with a foldable flip design. The adjustable viewing angle supports more comfortable operation and parameter observation across different working positions.
• Six Preset Output Groups: Supports six preset groups, M1–M6, each storing output voltage and constant current settings. Quickly switch between saved parameter groups from the main interface to reduce repeated manual configuration.
• Eight Safety Protection Mechanisms: Includes overvoltage protection (OVP), overcurrent protection (OCP), overpower protection (OPP), overtemperature protection (OTP), undervoltage protection (LVP), reverse input protection, reverse output protection, and reverse connection protection. When an abnormal condition is detected, the device displays a warning, automatically shuts off output, and activates a buzzer alarm. Output is prohibited under undervoltage protection.
• Real-Time Measurement & Output Statistics: Displays input voltage, output voltage, output current, output power, internal temperature, operating status, and output mode. Measurement functions support capacity, energy, and output time statistics, which can be reset when metering is enabled.
• Compact & Lightweight Portable Design: Measures approximately 106 × 76 × 28mm and weighs about 178g. Its compact form factor supports convenient transportation and mobile power testing where portability is important.
