Voltage: 120 volts 2-wire, 240 volts 2-wire, 120/240 volts 3-wire

Amperage: Up to 100 amps

Type: Pass-Through, Single-Phase, 60Hz

Data: Pulse Output - 800 pulses per kWh

Model: EKM-25XDSE

This new meter model has been designed to replace both of our legacy single phase pass-though kWh meters (EKM-25IDS and EKM-15IDS). The EKM-25XDSE replaces the functionality of both of these legacy meters and offers a number of additional improvements to their designs.

Compact and very easy to install. Simple DIN-Rail Mounting. Wires pass through 13.7mm (0.5 inch) diameter tubes in the meter body -- Will accept 22 AWG – 1 AWG wire. There are two piercing screws that pierce the wires that pass through the meter. The meter comes with two sets of bushings for medium and small wire diameter wires, which keep the wires centered so the piercing screws have no trouble engaging the conductor. The upside-down teardrop shape of the tubes also serves to keep the wires centered.

Single Phase 120/240V 3-Wire (2 hots, 1 neutral):
In this configuration both hot wires pass through the body of the meter. The piercing screws are used to pierce the wire insulation to provide the meter with a voltage reference for each line. There is also a port on the meter for a neutral reference. The meter will function without this connection (at ~1% accuracy) but it will be 0.5% accurate with the neutral connection.

Single Phase 120V or 208-240V 2-Wire (2 hots):
As described above, the meter is designed to meter single phase electrical systems that don't have a neutral available. Both hot wires pass though the body of the meter and the piercing screws are used to pierce the wire insulation to provide voltage references to the meter.

Single Phase 120V or 208-240V 2-Wire (1 hot, 1 neutral):
In this case Line 1 passes though the tube marked L1. The piercing screw is used to pierce the wire insulation for L1 to provide the voltage reference to the meter. The Neutral reference can either pass through the Tube marked L2 or it can be connected to the port marked N. If the neutral passes though the L2 tube then the piercing screw is used to pierce the wire insulation for to provide the neutral reference to the meter.

State-of-the-art, fully solid-state kWh meter with 800 pulse per kWh pulse output.

0.5–1% accuracy dependent on setup (see above), LCD readout in hundredths of a kWh, to 99999.99 kWh. No conversion factor or multiplier.

Non-resettable LCD display. kWh data is maintained through power outages, and for up to 10 years without power.

QUESTIONS & ANSWERS

Ask a Question
  • EKM-25XDSE How does the pulse output monitoring work? How/what do you install for the pulse monitoring?

    The Basic Pulse Output of all of our electric meters is a non-powered open/close switch (though solid state - not a mechanical relay). Electrically the Pulse Output is very similar to the closing of a dry contact switch, such as a Reed switch.

     
    Pulse width: 90ms
    Compatible voltage (the meter itself does not put out a voltage): up to 27V max
    Current range the meter's pulse output can handle: ≤27mA
    The EKM-25XDSE pulses 800 times per kWh. Or: one pulse per 1.25 Watt hours (its little red LED will flash as well with each pulse).

    You could potentially wire this pulse output to some kind of basic pulse counter that would put that low voltage on the line and count how many pulses were created, and you could then translate that into total kWh metered. However we generally recommend our Omnimeter line of meters instead if you need data output, as you can take advantage of our Push system, for instance, to get all kinds of great data delivered to your computer.

  • What are dimensions

    Here is a link to the spec sheet for this meter:  https://documents.ekmmetering.com/EKM-25XDSE-Spec-Sheet.pdf

    The dimensions of the EKM-25XDSE are:

    100mm tall
    88mm wide
    65mm deep

  • Are your products approved by the Canadian Safety Association?

    Our Omnimeter II v.3 UL and our Omnimeter Pulse v.4 UL are both UL and cUL (Canadian UL) listed.  These are tested and certified to the exact same 61010-1 safety standards as CSA (Canadian Safety Association) and can be used in Canada without issues.  We have a lot of customers in Canada that use these meters.  Here is more information about our certifications:  https://help.ekmmetering.com/support/solutions/articles/6000068358-do-your-meters-have-any-certifications-


    The EKM-25XDSE is not UL listed or CSA approved.

  • I would like to install a submeter to determine how much electricity teh suite in my house is using. Would I use a 120V meter or a 240v. Or does it make any difference. Someone else said I should use a 240v but I am concerned that since we use 120v here that the meter will only show 1/2 of the actual electricity used. I am in canada.

    For this install, the EKM 25XDSE would work well for you.  I assume you have 2 hot wires and a neutral wire, what we call 120/240 volt 3-wire.  The voltages you measure depend on which wires you measure between.  If you measure between the 2 hot wires you will get ~240 volts, if you measure between either hot wire and neutral, you will get ~120 volts.  This is the most common residential system in the USA.  Is this what you are seeing in your electrical system?  The EKM 25XDSE will work for you because it has 2 internal CTs and can accurately meter an USA residential unbalanced load.

  • I am planning to install this unit in an area where the temperature can fall well below freezing. Can the LED screen handle the low temperatures?

    Yes, I dont think you should have any trouble at all, we have never had trouble with the LCD screens or our electric meters in general due to the cold.  We have them installed all over the world, including very cold environments (particularly in Canada and Alaska).  They are rated to -30°C to 70°C (which is -22°F to 158°F).  Here is the spec sheet for this meter:  https://documents.ekmmetering.com/EKM-25XDSE-Spec-Sheet.pdf

  • Can I use it to run a 240 v laundry dryer

    Yes, you can use the EKM 25XDSE to meter a 240 volt dryer.  Your dryer will either have just 2 hot wires or 2 hot wires and a neutral wire.  This meter will work in both situations.  Here is the spec sheet for the 25XDSE:  https://documents.ekmmetering.com/EKM-25XDSE-Spec-Sheet.pdf

  • Does this item show thru current, or only the total of kwh's? I would like to bee able to see the flow of current. Thanks

    The EKM-25XDSE only shows the total kWh. Our Omnimeter models, however, do cycle through various display values - including Amps (current).

  • What is the voltage of each pulse?

    The Pulse Output of all of our electric meters is a non-powered open/close switch (though solid state - not a mechanical relay). Electrically the Pulse Output is very similar to the closing of a dry contact switch, such as a Reed switch.
     
    Pulse Output Specs:
    Impulse width: 90ms
    Compatible voltage (the meter itself does not put out a voltage): 27V max
    Current range the meter's pulse output can handle: ≤27mA
    These pulse 800 pulses per kWh, so this means that for every 1.25 Watt hours there will be a pulse from the meter (its little red LED will flash as well with each pulse).

  • I need a rain tight enclosure for this meter or is it men’s 3R?

    Both of our watertight enclosures should work well. Here is our smaller model:
