Single-Phase Digital Current Voltage Panel Meter
See Electrical Values Clearly at a GlanceDesigned for single-phase electrical monitoring, the meter provides direct digital indication of AC current or voltage with 0.2% FS ±1 digit measurement accuracy. The display refreshes three times per second, giving operators a clear and continuously updated view of electrical conditions. | |
More Than a Display — Connect It to Your SystemBeyond local LED indication, the meter can support RS485 Modbus-RTU communication, analog transmitter output and relay switching functions. RS485 communication supports transmission distances up to 1200m at 9600bps with shielded twisted-pair cable, allowing measurement data to be integrated into remote monitoring and automation systems. | |
Stable Measurement in Electrically Noisy CabinetsThree-port galvanic isolation separates the measurement input, power supply and output/communication circuits, with 2000V AC RMS dielectric withstand capability. Industrial EMC protection against ESD, EFT, surge and RF interference helps maintain stable measurement in electrically noisy distribution and automation cabinets. | |
