D52-2042 Double Display Guide Rail Digital Voltmeter Digital Display AC Voltmeter AC Current Meter
A part of the review has been auto-translated.
Goods arrived in good shape , inside a carton box each, along with user instructions .. A connection diagram is also printed to the side of the meter. Practically L+N for the voltmeter to work. As for the Ampere- meter the max cable thickness is up to 1 cm , there exists the relevant hole, where the cable leading the power to the "load" has to go through there .. Not tested it yet , have to do some modifications in my panel including a over-under voltage protection , also sold through Banggood
Goods arrived in perfect shape, descent packaging, along with instructions paper in box. There exists a "connection diagram" printed to the side of the item as well. The two screws are for the Voltage meter part, while there exists a hole, 1 cm in diameter, where the cable providing the power to the "Load" goes through it for the Ampere meter part. Nice "large" digits ... Red for the Voltage - Green for the Amperes ... Not installed yet, to test it , as it arrived yesterday .. I plan to pair it with an Over-Under Voltage Protector in my panel ( sold in Banggood as well .. check it out )
Works perfect, current is measured with magnetic coupling. voltage error ca 1 volt (acceptable)
The plastic is more tinted (yellow) than the appliances in the board, but it is not inhibitory because in the end well hidden under the hood. The display is clear and globally accurate: 1 volt deviation. The unit is integrated without the need for adjustment on the grid or the external cover. Very well for the price. To see in time for sustainability...
Received ok. It is the second item I bought. It is very useful in tracking the energy consumption.
Everything arrived OK, thank you.
Nagyon jó termék. Jó megjelenés . Pontos működés .
OK arrived fine waiting for wiring
I haven't cut it yet. But it looks good.
