The ND20LITE meter is a digital programmable panel meter destined for the measurement of single-phase power network parameters (2-wire network) and 3-phase, 3,4-wire network in balanced and unbalanced systems with the simultaneous display of measured quantities on a LCD display. The meter enables the control and optimization of power electronics devices, systems and industrial installation operations.

ND20LITE是一種數(shù)字式可編程面板儀表，用于測(cè)量單相電網(wǎng)參數(shù)(2線網(wǎng))和3相、3、4線網(wǎng)絡(luò)在平衡和不平衡的系統(tǒng)中，同時(shí)在液晶顯示器上顯示測(cè)量的數(shù)量。該儀表能夠控制和優(yōu)化電力電子設(shè)備、系統(tǒng)和工業(yè)安裝操作。
