The Based on microprocessor technology, the PME-20-PH is an instrument designed mainly as a phase angle meter, although other parameters, such as Frequency and Power Factor can be measured. The instrument has an analogic scale that enables it to be used as a synchroscope.
The instrument is mounted in a high resistance plastic box, reduced in size and weight. The instrument has two inputs, which are individualy isolated galvanically. This allows for a voltage input up to 500 V RMS and current input up to 25 A RMS, to be connected directly into the input taps. It is not necessary to change measurement ranges and scales. The phase angle is measured between these 2 inputs, with a resolution of 0.1º, regardless of the input values, magnitude (Voltage, Current), or the combinations used.
With external optional accessories the input values can be raised up to 750V and 1000 A.
The instrument is powered with 4 rechargeable batteries, with a capacity of 1.5 V and 1500 A/H, having a use of 6 hours, with a recharge time of 3 hours. An External battery charger is supplied with the instrument.
