In modern low-voltage switchgear (LVSG), every centimeter on the DIN rail and panel counts. Instead of installing separate ammeters, voltmeters, wattmeters, and varmeters, a single device is all you need — the PD194PQ-9R4T from the KS® brand.
This is more than just a meter; it is a full-fledged component for telemetry and industrial automation systems (SCADA). The instrument can be configured directly from the front panel (no PC required), and its three-line LED display provides excellent readability even from a distance.
What Can It Do?
The device monitors 31 power network parameters:
-
Voltages: phase, line-to-line, average, zero-sequence.
-
Currents: phase, average, zero-sequence.
-
Power: active, reactive, apparent (per phase and total).
-
Power factors: per phase and total.
-
Frequency: 45 to 55 Hz.
All data is transmitted via the RS-485 (Modbus RTU) interface. It also features a pulse output for integration into energy metering and monitoring systems.
