The registrars of current XL421, XL422, record the values of the signal of current in the necessary period

This instruments are intended for the measurement and the writing into the memory of the values of the signals of alternating current to 2500 [A]. [Pribory]s they record the values of signal they preserve them before the internal storage of registrar for the subsequent transmission of data on PK. Registrars have the built-in current-measuring tongs.
Model XL421 is intended for the single-phase networks
Model XL422 is intended for the three-phase networks

• Obtaining the accurate results of measurements because of the function Of trueRMS
• Possibility of the record of the values of signal during the long time to 6 months
• Connection for the sake of PK (RS-232)
• Storage of the given before the memory even in the absence batteries
• Indication of the discharge of batteries, the fitness for work of instrument due to the conditions of high humidity and low temperatures
