Verify the device requirements and connection polarity first.\u003c\/p\u003e\n\u003ch3\u003eDoes the supply always push 10 amps into the device?\u003c\/h3\u003e\n\u003cp\u003eNo. The connected load determines its current demand during constant-voltage operation. The current setting establishes the limit; reaching that limit can cause the supply to enter constant-current operation and reduce output voltage.\u003c\/p\u003e\n\u003ch3\u003eDoes this version include USB-C or programmable presets?\u003c\/h3\u003e\n\u003cp\u003eThis listing is for the red LED SPS-3010 with coarse\/fine adjustment knobs and a 5V\/2A USB-A port.
