 B016LGLALE Availability: Currently unavailable Score: 7.042 Category: Electronics Rating: 5 Votes: 1 Find similar productsAMPS Real HIGH POWER Watt Meter 180A BIG WIRE HEAVY 8 AWG Solar/Wind Turbines. This meter is a RARE find with THE heavy 8 Gauge silicon wire since most meters only use 14G wire and can't take high amps at low voltages like 12 volts which is common in wind turbines. Custom Made For The Wind Industry. BACK LIT LED SCREEN FOR EASY NIGHT VIEWING . All other meters in the 180 AMP class only have 12G wires and those can get VERY HOT when used on 12 and 24 volt systems! Make very sure that you buy the only meter on the market made with heavy 8 Gauge wires. Buy ours or be sorry. Works on all 4, 6, 12, 24, 36, 48 and 60 Volt Systems This all range Amp / Watt meter is also a powerful data logger that keeps track of AH Wh Vh Vm, load time and more. It also works on all systems including all 4 to 60 volt systems with a full voltage range up to 60 volts. It can also handle 180 amps surge and operate at 140 amps continuous at 6 volts. Works on all wind turbines, solar panels and hydro systems up to 60 volt DC input. It can also work on AC three phase systems after the rectifier. Also measures accumulated Amp Hours, Watt hours, Volt minutes and Watt production. Truly amazing to have so many features packed into this small meter. |  B08YWHPQM7 Price: $180.7 Score: 6.897 Category: Electronics Rating: 5 Votes: 1 Find similar productsciciglow Digital SWR/Watt Meter,DG-503 Digital LCD 3.5 SWR/Watt Meter 1.6-60MHz/125-525MHz SWR Meter for Two-Way Radios Professional Meter Tool for Radios. . |
