It measures key electrical parameters including voltage, current, frequency, power factor, active power, and total energy consumption, all displayed on a clear LED display. The meter supports two voltage input ranges—AC 50–300V for single-phase applications or AC 250–450V for three-phase applications—allowing users to select the appropriate model based on their system requirements. With a current measurement range of 0–99.99A, active power up to 30,000W, and energy accumulation up to 99,999 kWh, this meter is suitable for a wide variety of monitoring tasks. It features automatic data saving during power loss and includes a reset button for clearing energy readings. Housed in a compact 49×47×52mm enclosure with a Φ22mm mounting hole, the TOVM48S is ideal for panel mounting in industrial, commercial, and residential power distribution systems.\u003c\/p\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cp\u003e\u003cbr\u003e\u003cspan style=\"font-size:24px\"\u003e\u003cstrong\u003eProduct Data Sheet\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cp\u003e\u003cbr\u003eModel: TOVM48S\u003c\/p\u003e\n\u003cp\u003eType: Multi-function Digital Meter\u003c\/p\u003e\n\u003cp\u003eDisplay: LED\u003c\/p\u003e\n\u003cp\u003eMeasured Parameters: Voltage, Current, Frequency, Power Factor, Active Power, Total Energy\u003c\/p\u003e\n\u003cp\u003eAccuracy: 1% ±2 digits\u003c\/p\u003e\n\u003cp\u003eVoltage Range (Single-phase): AC 50.0–300.0V\u003c\/p\u003e\n\u003cp\u003eVoltage Range (Three-phase): AC 250.0–450.0V\u003c\/p\u003e\n\u003cp\u003eCurrent Range: AC 0.0–99.99A (resolution: 0.01A below 100A;
