systems?\u003c\/h4\u003e\n\u003cp\u003eA: No — this panel meter is designed for \u003cstrong\u003eDC circuits only\u003c\/strong\u003e. It measures DC voltage from 0–100V and DC current from 0–10A. It should not be connected to AC power systems.\u003c\/p\u003e\n\u003ch4\u003eQ: Does the meter need a separate power supply to operate?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The meter requires an external DC supply of \u003cstrong\u003e4–30V\u003c\/strong\u003e to power the display. If the meter's supply and the load share the same source and the load voltage is within 4–30V, the same supply can be used. If your load voltage exceeds 30V, a separate 4–30V power source is required for the meter itself to avoid damage.\u003c\/p\u003e\n\u003ch4\u003eQ: How do I mount this voltmeter ammeter into a panel?\u003c\/h4\u003e\n\u003cp\u003eA: Cut a rectangular hole of \u003cstrong\u003e46 × 27 mm\u003c\/strong\u003e in your panel or enclosure, insert the meter from the front, and secure it with the included clips or friction fit. The total body size is 48 × 29 × 21 mm, so the bezel will sit flush against the panel surface.\u003c\/p\u003e\n\u003ch4\u003eQ: What do the red and blue LED displays show?\u003c\/h4\u003e\n\u003cp\u003eA: The \u003cstrong\u003ered LED digits\u003c\/strong\u003e display the measured voltage, while the \u003cstrong\u003eblue LED digits\u003c\/strong\u003e display the measured current. Both readings are shown simultaneously, making it easy to distinguish values at a glance without confusion.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"Can this digital voltmeter ammeter be used with AC power systems?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"No — this panel meter is designed for DC circuits only.
