td4100 calibrator for three-凯发k8国际

overview

model td4100, an intelligent and highly integrated calibrator for three-phase apparatuses. it integrates a variety of measurement and calibration functions, and can be regards as a small mobile electronic s laboratory. the optional accuracy classes are 0.02 and 0.05.

applied to calibrate three-phase apparatuses, multimeters, transmitters and other electrical measurement devices.

this calibrator complies with the following standards:

● jjg 124-2005 verification regulation of amperemeters, voltmeters, wattmeters and ohmmeters

● jjf 1284-2011 calibration specification of calibrators for electrical meters

● dl/t 1112-2009 verification code of verification equipment for ac&dc meter

applications

features

● three-phase electrical parameters output: the voltage is up to 825 v, and the current is up to 55 a (phase a is 110 a).

● dc electrical parameters output: voltage is up to 1100 v, current is up to 55 a.

● ac power output: active power, reactive power, apparent power and power factor.
