Frequently Asked Questions
Q: What does the 8-in-1 measurement feature mean on this AC power meter?
A: The 8-in-1 design means the KWS-302 power meter simultaneously measures and displays eight key electrical parameters: voltage (V), current (amps/A), power (watts/W), energy consumption (kWh), timing (hours), temperature (°C), frequency (Hz), and power factor (PF) — all on a single color screen, giving you a complete picture of your electricity usage at a glance.
Q: Can I control this energy meter remotely from my phone?
A: Yes — the KWS-302WF model features built-in WiFi connectivity, allowing you to monitor readings and control the meter remotely via your smartphone at unlimited distance. The KWS-302L and KWS-302 models do not include WiFi functionality.
Q: How is this power meter installed?
A: The meter uses a standard DIN rail (guide rail) snap-on mounting system. No screws are required — simply clip it onto a compatible guide rail and wire it according to the included wiring diagram. Always ensure the power is off before installation and follow the diagram carefully for safe setup.
Q: Does this meter protect against voltage fluctuations?
A: The KWS-302WF (WiFi) and KWS-302L models include both overvoltage and undervoltage protection, automatically cutting power to prevent damage to connected devices during voltage irregularities. The basic KWS-302 model does not include voltage protection or power-off memory.
