ITEM NAME:150A Watt Power Analyzer Rc 150A High Precision Watt Meter And Power Analyz R9W6 150A Watt Power Analyzer Rc 150A High Precision Watt Meter And Power Analyz R9W6 Prevents peak currents damaging battery,ESC,motors,wiring and connectors,Verifies sufficient operating voltage under load,Individual cell balancing.Set cutoff voltages,check battery capacity health,Confirms proper battery charger operation(connect between your battery and charger) Detect receivers and actual operating current so as to make sure whether an UBEC is needed,Blue backlit LCD display,Operates from 4.0-60V,Suitable for 4,6,12,24,36 and 48 volt battery pack systems.Very low 7 mA power consumption.More efficient than any LED meter. The digital LCD LIGHT UP screen provides clear digital readings.Return to LIT.handles currents up to 150 amps and continuous operation 75 amps(48 volts),Microprocessor control produces very accurate and accurate readings.Uses optional auxiliary equipment to measure down to 0v(perfect for battery stress testing) Amplifier Peak(Ap)- The highest amplifier value delivered(usually startup cycles for inverters,compressors,refrigerators,etc.),Voltage - Supply voltage and minimum supply voltage.Suitable for measuring voltage at the lowest power point(such as the minimum nighttime voltage of a car refrigerator battery) During charging,the meter can "turn" to measure the amount of power returned to the battery.In this case,the charger(DCDC,solar,main battery charger)is connected to the power supply,and the battery is connected to the "load".Charge cycle readings:Amplifier Peak(Ap)- The maximum charge available to the battery(Big Charge),Voltage - Point-in-time voltage from charger(charger not charging or under charging) Colour:Black material:plastic Size:85 x 42 x 25mm Package Contents: 1 x 150A Watt Meter and Power Analyzer 1 x English user manual
