Measures DC Power and shows totalized Ampere Hour and Watt Hour. LCD Screen 16character x 2 line. Powered by load or source. Max DC input voltage 30V. Max DC current measurement 50A. Display shows DC Voltage, Current, Wattage, Ampere Hour, Watt Hour, Minimum input voltage, Maximum current. Great for totalizing power to battery from AC Charger or Solar source or measuring UPS power consumption. DIN 96×96 Instrument case unit for up to 60V DC input. Introduction: Solar Power Meter measures and calculates electrical parameters for Solar Installations. Features Measures energy (Wh), charge (Ah), power (W), current (A) and voltage (V) Accurate & precise – 0.01 A current and 0.01 V voltage resolutions Measures peak Amps, peak Watts and voltage minimum (droop) Rugged – handles 50 A continuous and 60 A peak at 30 V2.5SqMM multistrand insulated wire flying leads connect to input and output Small & light with a tough plastic case Acts like a wire so doesn’t affect load performance. Precision Alu-Chrom current Sensing resistor, with only 0.001 Ohms resistance and circuitry that draws only 17 mA Factory calibration stores constants in EEPROM to compensate for component tolerances Powerful, 8 MIPS micro-controller Made in INDIA to quality standards One-year warranty and complete user manual
