The MA501-110V-CU is an LCD ammeter designed for single-phase AC current measurement with True RMS capability and integrated phase selection. It features a 4-digit LCD display with backlight and analog bargraph indicator, displaying current ranges from 0 to 6200A with a manual phase selector switch for flexible operation. The meter operates on 110 VAC ±20% at 50/60 Hz and measures input currents from 50mA to 5A directly, with external current transformers (CT) required for currents exceeding 5A. With an accuracy class of ±0.5% of full-scale value, a sampling rate of 2 samples per second, and programmable CT primary values ranging from 5A to 5000A, this meter is ideal for industrial power monitoring, electrical panel installations, and energy management applications requiring reliable current measurement.
