              This new and renewable power meter has the capacity to measure both AC and DC,

              as well as active/standby power consumption and features a consumer-oriented design

               with an excellent performance vs. price ratio.

              The HPM-300A is able to measure and display four power related items, including voltage,

              current power and frequency simultaneously on a wide LCD with the capacity to measure up to 11 items, i

              ncluding power factor and wattage. In addition, it can measure a high power of 5A or more up to 1,000A

              with the use of the AC/DC clamp sensor, and three phase four wire power with the use of the three wattmeter method.



              Built-in lithium-ion battery for recharge

              Anti-shock holster

              Easy measurements and metering with the use of AC/DC load wires (single-phase)

              LCD display measurement items (voltage, current, power, power factor,

               frequency wattage, and reactive power)

              AC/DC clamp sensor

              Free of charge GUI PROGRAM (calculates electric charges on your PC, check out CO2 emissions)

              Size and weight: 100(W)X200(H)X45(D)㎜. ≒ 200g






              The HPM-300A is designed to measure single-phase power. However, it can also measure three-phase power.

             Below is an application of measurements. It is recommended to proceed with these measurements

              by referring to the examples below if buying a three-phase power meter is beyond your budget.



              The measurements have been made by the Kyoritsu (KEW-6310) power quality analyzer to identify if measurements are correct.

              First, check the type of power to be measured.

              Our factory uses three-phase four-wire power system, which is typical in Korea.  

              The connection diagram is as follows.

              Three-phase four-wire power system (3O, 4Wire)


As shown in the diagram, the connections have been made at the distributing board.



Three units of HPM-300A

Three-phase power meter of Kyoritsu

              Let us enlarge the measurements to facilitate identification.

              Adding the value of three units of HPM-300A,

              you will see that the measurements are the same as those made by Kyoritsu power meter, which is 4.48kw.

              This means, all you have to do is to combine the three single-phase powers for power,

               and to divide the sum of each phase by 3 for power factor.

              If you only have a single unit of HPM-300A,

               you should make three measurements and add them up.

              However, considerations should be made as excessive change in load or input power may cause a significant measurement error.

              On top of this, the HPM-300A manual provides a connection diagram

              depending on the type of power for your reference purposes.
