FNIRSI DPS-150 Mini Adjustable DC Power Supply

The FNIRSI DPS-150 is a compact, CNC-programmable regulated DC power supply designed to fit perfectly on any FPV builder's workbench. Whether you need a stable voltage source for testing standalone flight controllers and video transmitters, or a current-limited supply for safely powering up a new quadcopter to check for shorts, this unit delivers precise electrical control. Its minimal footprint saves valuable desk space and makes it easy to pack for field repairs, while the programmable interface allows for repeatable, accurate testing of your drone components.

Key features

• Fully adjustable output voltage and current for safe component testing and short-circuit prevention.
• CNC-programmable interface featuring memory presets, allowing you to quickly jump between common FPV voltage levels.
• Housed in a rigid CNC-machined aluminium enclosure to withstand daily workshop use and transport.
• Clear digital screen provides real-time monitoring of voltage and amp draw, essential for diagnosing electrical faults.

A reliable bench power supply is an essential diagnostic tool for preventing blown regulators on freshly soldered stacks. The DPS-150 handles everything from low-current receiver binding to full-system voltage checks with accuracy.
