    in reply to: Relay not functioning? #36772

    Hello Kevin f,

    There may be still some misunderstanding.  The third port is not  always negative. And there are no inner connection between the first and fourth terminals.

    If it is hard to get through the first wiring diagram , you can  refer to the second one, that should be more easy to understand how the terminals work.

    It is not necessary to distinguish the polarity for thrid terminal and the last terminal. Conversely, you can also connect power positive to third terminal and negative to the last terminal.

    It doesn’t matter how you connect power supply to these two terminals, they  just work as a switch, which can control the power to load.

    Best regards.

    in reply to: Relay not functioning? #36765

    Hello kevin f,

    As per your description, it seems you only connect power supply for relay.

    Please kindly notice that relay doesn’t offer power for load.  You can connect another power supply for load or just use the same power supply, as shown below.

    Hello Paul Welte,

    Is it this item? 200075

    The new version is as what you mention, there is not connector for power supply terminal. You can solder wire directly.

    Any more questions, please kindly let us know.

    Best regards.

    in reply to: SKU 200219: Arrow Mark on Hall Sensor? #36743

    Hello Nigel Shindler,

    You can put negative cable into sensor, but actually it is not necessary to do that. As long as the current direction changes, sensor can check it at once.

    Meter consuming power is around 0.7W

    Best regards.

    Hello Hugo Lagrandeur，

    We think it should be this item. 200141

    Even though you disconnect power, kwh data is still there. It will keep accumulating unless you reset it.

    Best regards.

    in reply to: DROK 180050 voltage reegulator #36704

    Hello kevin cooper，

    There is no special adjustment way. As what you mention. It is clockwise or anti-clockwise. Therefore we  sincerely hope to check how it is from video. For example, display, connection, your operation. We will pass it on to technicians to check what wrong it is. Is it possible to take a better video or some images?

    Best regards.

    in reply to: The battery indicator fluctuates with the voltage of the battery #36700

    Hello Freddy Huyghe，

    200192 is voltage-type metr. Measurement is related to battery voltage. When there is high power, battery voltage will drop a lot.

    You can think about coulombmeter, which can show stable reading. For example, 200312, 2001712003

    Best regards.

    in reply to: 80-300v 0-100amp CT power meter #36692

    Hello Matt Holmes,

    Our AC meter only read active power.

    There are three kinds of power. Active Power,Reactive power and inspecting power.
    Here we just talk about active power.
    The calculating formula for active power is P=U*I*cosφ( cosφ represents power factor). As different load have different power factor, the current and active power is also different.
    In general,we use P=UI, because the power factor of pure resistive load is closed to 1
    The power factor of inductive and capacitive loads is between 0-1.
    So when you test the pure resistive load, P is equal to or near U*I; but when you test the inductive and capacitive loads (e.g.television,computer), P< U*I.

    Any more questions, please kindly let us know.

    Best regards.
