Digital Power Meter for DIN Rail 8.2 x 5 x 2.4 cm KWS-303 Voltmeter Ammeter Energy Meter AC 85-290 V 40 A
The KWS-303 digital meter represents a comprehensive solution for accurate monitoring of electrical parameters in homes, workshops, and professional distribution boards. This device provides an instant overview of voltage, current, power, frequency, power factor, and total energy consumption, all in real-time on a clear colour display. With compact dimensions of 8.2 x 5 x 2.4 cm and installation on a standard DIN rail, it is suitable for most electrical installation systems. The device operates within a wide voltage range of AC 85–290 V and measures current up to 40 A, ensuring universal use in low voltage applications. Overvoltage, undervoltage, and temperature protection contribute to safe operation.
The KWS-303 also supports temperature measurement using an integrated NTC sensor and can retain energy data even during a power outage thanks to its memory function. Control is straightforward using three buttons that allow for display changes and basic settings. With high measurement accuracy, clear graphical presentation, and rapid value updates twice per second, this device is ideal for monitoring the consumption of individual circuits or appliances. Its design excludes Wi-Fi functionality, timers, and data export options, which will be appreciated by users seeking a reliable device without complicated configurations.
- Precise measurement of electrical parameters – voltage AC 85–290 V, current 0–40 A, power 0–12 kW, and energy 0–99999 kWh.
- Integrated NTC sensor – temperature monitoring in the range of −20 to 150 °C.
- Rapid value updates – measurements occur twice per second.
- Safety protections – overvoltage, undervoltage, overheating, and memory during power failure.
- Compact dimensions 8.2 x 5 x 2.4 cm – easy installation on DIN rail in the distribution board.
- Clear colour display – prominent display of voltage, current, power, kWh, frequency, and power factor.
- Simple operation – ON/OFF buttons, + and − for switching between modes.
- Energy memory – consumption values are not erased even when power is disconnected.
- No Wi-Fi, no timer, no RS485 communication – stable and reliable measurement without configuration.
- Package contents: 1× digital meter KWS-303
