LED Voltmeter Ammeter Blue Red LED 100V 10A Meter

WHAT IS ITA Self-Powered Voltage Ammeter (for voltages < 30V) consuming < 20mA. Voltages > 30V require a separate supply. WHAT IS IT USED FORTo display the voltage and current along two wires. HOW DO I USE ITTwo clip in plugs with wires are provided to hook this into your supply. \nPut the current in the -ve return, and the red and yellow voltage sense wires to +ve. \nSee the pictures for wiring. TECHNICAL SPECIFICATION\nSupply voltage: 4.5 - 30V \nVoltage measurement range: DC 0-100V\nCurrent measurement range: DC 0-10A\nDisplay screen: 0.28 inch LED\nOperating current:<20mA\nMeasuring speed:\u2265 500mS / times\nAccuracy: \u00B1 1%\nDesigned to clip into a rectangular hole 45.4mm x 26.5mm\n30mm deep with the plugs in, requiring another 10mm or so for cable bend.\nSee the pictures for connection details.OBSERVATIONSNice bright red and blue LEDs give a crystal clear readout\nQuick reaction time\n\nSee my other interesting power suppli.
