ACM20 Series www.murata-ps.com Four-Function AC Power Meters PRODUCT OVERVIEW Actual size C US E156931 Murata Power Solutions ACM20 series AC power meters display the most critical measure- ments in mains-powered equipment: voltage, amperage, active power (watts), and power factor. A front panel selector-switch provides two modes of operation: a fixed reading of FEATURES any of the four parameters, or a continuous cycling through all four measurements. An n Displays AC Volts, Amps, Watts, and Power Factor or Hertz optional model displays line frequency with 0.1Hz resolution. All ACM20 multi-function n Two display modes: continuous auto cycling or fixed power meters include built-in current transformersno other user-supplied components are required. n Universal 85-264Vac (47-63Hz) operating range (Measurement Category II) ACM20 series AC power meters are available in a choice of three input ranges: 0-10A (with n Built-in current transformers simplify installation choice of 0.001A resolution, 999.9 watts max.) 0-32A (with 0.01A resolution, 9999 watts max.) and 10A, 32A, or 100A ranges 0-100A (0.1A resolution, 26.4kW max.). An 85-264Vac (47-63Hz) operating supply range makes these power meters perfect for worldwide power monitoring applications. And, n Ideal for power distribution units (PDUs) and power strips unlike conventional, average-responding products, ACM20 power meters can accurately n True-rms readings of complex voltage and current waveforms display the real power and true-rms current values of triangle waves, square waves, and n Low-power consumption: less than watt from 120Vac other irregularly shaped waveforms, with a typical accuracy of 1% of full scale. n One-piece polycarbonate housing fits 0U & 1U racks Their large (0.36 /9.2mm), bright red LED display makes ACM20 AC power meters easily n Surface mount design occupies minimal panel space readable from as far as 15 feet (5 meters). All units are packaged in a one-piece, vibration resistant, polycarbonate housing that can be installed in vertical 0U and 1U rack spaces. n Bright red LED-display with four annunciators Their miniature size is perfect for UPS power sources, power strips, laboratory instrumenta- n Optional Frequency reading models (0.1Hz resolution) tion, alternative energy applications, and any other products that require precise monitoring n Approvals to UL/CSA/IEC/EN 61010-1 of AC power.

Measurement Type: ACM20 series multifunction AC power meters Current Accuracy (3) 1% employ a precision energy metering integrated circuit and a low- power microcontroller to measure and display the rms voltage and Power Accuracy (3) 2% current, active (real) power, power factor (or line frequency on F Frequency Accuracy (3) 0.1 Hz suffix models) of ac mains supplies from 47-63Hz. Please note, Power Factor Accuracy 3% ACM20 power meters use the voltage present at their TB1 terminal Measurement Bandwidth 140Hz (Voltage), 14kHz (Current) block and the secondary current of their built-in current transformer L1 to calculate and then display VOLTS, AMPS, WATTS, power factor Temperature Drift (0 to 60C) 0.5 Counts/C (PF), or line frequency on -F HERTZ models. Zero-Current Reading (within 2 sec.) 0.00 Amps While the ACM20 displays the rms value of line voltage and line Zero-Power Reading (within 2 sec.) 0 Watts current, the VOLTS reading has an upper limit of 140Hz (-3db point), UL/IEC61010-1 Measurement category II which means rectangular-shaped voltage waveforms, and waveforms Supply Voltage (TB1) (Measurement Category II) with sharp transitions, will read lower than their true-rms value. For All Models 47-63 Hz 85 120 264 Vac example, a square wave line voltage will read approximately 1-2% Supply Current (4) lower, a triangle wave will read 3% lower, and a modified sine wave will read 18% lower. The oscillograms on page seven illustrate typical All Models 35 50 110 mA ACM20 VOLTS readings when powered from four ac waveforms. Power Supply Terminal Block The 140Hz bandwidth limit does not apply to the WATTS reading nor Wire Size 16-22AWG, solid or stranded to the AMPS reading. The circuitry used for these two measurements Insulation Strip Length 6.4mm (0.250 in) has an upper bandwidth of 14kHz. ACM20 power meters are mains Screw Tightening Torque 0.4Nm (3.6 lb-in) operated devices designed to measure ac currents and voltages, Rated Voltage 300Vac within the specified limits previously noted. DC currents and voltages will not be measured accurately. Display Display Type and Size 4 Digit LED, 9.14mm (0.36in) high 2. Basic Operation: Upon application of ac power to TB1, the unit will first perform a self-test routine and then continuously display ac volts Overrange Indication Flashing 9999 Watts (5) with the VOLTS LED annunciator illuminated.
