## Description

Pass-through DIN Rail 120 240 Volts. KWh energy meter - desertcart.com

Review: JUST AS ADVERTISED - Hooked to 240 volt sub box as instructed, turned power back on, and it is working as advertised. Great little device to measure power use at a secondary breaker box, and required no special wiring. Two hot wires pass through matching opening in device, hook back up to main lugs, screw two small screws into those hot wires, turn on power, and it cumulatively measures kwh. Perfect, at a reasonable cost.
Review: Easy to use. - I was doing some research into how much power my mini splits were actually using. I pulled the wires from the breaker, crimp spliced an extension, and VoiLa! Super fast, super easy, and only temporary for a 30 day sampling. I do wish it had a 0 reset option, but other than that, it seems well made, from sturdy materials. I would definitely recommend this meter.

## Questions & Answers

**Q: What is the frequency of the pulse output and how often is it updated? 27VDC? PNP or NPN?**
A: It's not a radio frequency, you connect two ports from the meter to a pulse reader no polarity. It is 800 pulses per minute, passive.

**Q: Can this be used for 4500 Watt - dual element electric water heater? I am concerned about the wattage/ rating of this meter.  Thanks**
A: Yes,  up to 100 Amps,  so even if the water heater is 120V then 120 x 100 = 12000 Watts Max.   Most likely your heater is for 240V then the max watts in that case would be 240 x 100 = 24000 Watt.  So in either case the Amps will be within the meter's range of 100 Amps.  In other words,  what matters for the meter is the Amps. They have to be less than 100 Amps.  In you case 4500÷120=37.5 Amps. Or most likely 4500÷240=18.75 Amps.  Even better.

**Q: Must the current flow in the direction of the arrows?  My source would be below the meter and the load above.**
A: As far as I know, yes, I haven't tested it on the opposite direction,  O would put the meter upside down in that case, and take pictures every month for the reading ...

**Q: Will the meter  run backward for solar panels?**
A: I don't think this meter reads backwards.  I would try this one for one phase:

### ⭐⭐⭐⭐ Quick fix!
*by P***Y on August 21, 2022*

Works as described. The only problem is the screws that tap the wires are a bit flimsy so if the wire is just a little too big to use the bushings, you have to really hold the wires steady to get them to cut into the Insulation as theres enough space the screws just go around the wires. After installing it I wish I had just drilled the bushing out to fit my wire. That would have been a fix.
