The DP301AN-AC is a low-cost, compact 3-1/2 digit
panel meter for AC power line monitoring. It uses a
half-wave rectifier calibrated to read the RMS value of
sinusoidal signals.
Two input ranges are jumper-selectable: 50.0 to
199.9 Vac with 100 mV resolution and accuracy
optimized for 115 Vac, and 50 to 650V with 1V
resolution and accuracy optimized for 230 Vac. The
meter fits a standard ¹/8 DIN panel cutout 92 x 45 mm
(3.62 x 1.77") and requires a depth of less than 104 mm
(4.1") behind the panel. A screw-terminal barrier strip
for signal and power is standard.
Mechanical options include a board-edge connector
display TEST, display HOLD, +4.7V and -4.7V outputs
splash-proof lens cover which meets NEMA 4 (IP65)
requirement is available for industrial environments.
Power options isolated 9 to 32 Vdc and 26 to 56 Vdc.
SPECIFICATIONS Noise Rejection (AC GND to SIG GND) CMR: 120 dB, DC to 60 Hz CMV: 1500 Vp per HV test, 354 Vp per IEC spacing
