L20000RMA4

The L20000RMA4 is a Digital Panel Meter with exceptional performance at half the price of a bench top meter. It can measure true RMS current or voltage of AC signals where there is considerable distortion of the waveform, such as rectifier outputs or waveforms chopped by a SCR, TRIAC or transistor circuit. It is configured for universal 85 to 264VAC power, no relays, no analogue output and no communication option. True RMS readings in 0 to 16ms after completion of one input signal cycle allow anomalies to be detected and alarmed before they become expensive problems. Fast ON/OFF control and alarm can be achieved. The meter can also capture peak and valley readings for each 50/60Hz line cycle. Accuracy is 0.1% of full scale for signals from DC to 10kHz and signal amplitudes down to 0.1% of full scale. The crest factor (Vp/Vrms) is 3.0 at full-scale Vrms of 20000 counts and a Vp 60000 counts. AC or DC coupling is jumper selectable on the signal conditioner board.

• All ranges factory calibrated
• Scalable to 5 digits for external current shunts or 5A current transformers
• Selectable peak or valley display
