D52-2066 6-in-1 AC Power Monitor DIN Rail 110V 220V 380V 100A Voltage Current Power Factor kWh Frequency

Managing a circuit effectively means knowing more than just the voltage. The Soltree D52-2066 is a 6-in-1 multi-function AC power monitor that gives you a complete real-time view of your circuit's electrical performance — voltage, current, active power in watts, power factor, cumulative energy in kWh, and supply frequency — all displayed simultaneously on a high-resolution color screen, without needing separate instruments for each parameter.

The D52-2066 supports both single-phase (110V/220V) and three-phase (380V) systems, with two selectable voltage range options: 40–300V for standard single-phase and low-voltage applications, and 250–450V for three-phase and industrial circuits. Current measurement covers 0–100A (0.01A resolution), compatible with both built-in and external current transformers (CT) for flexible installation. Sampling rate is 2 times per second with ±1% ±2-digit accuracy across all parameters.

Energy consumption data is stored automatically during power outages — no readings are lost when the circuit is interrupted. The SAM CK button resets the kWh counter when needed (hold 5 seconds). Compact 54×80×64mm footprint installs on standard 35mm DIN rail. Suitable for home energy monitoring, industrial circuit analysis, and photovoltaic system performance tracking. CE certified, flame-retardant PC housing, operating temperature -10℃ to +50℃.
