Energy Meter for DIN Rail 8 x 6.4 x 5.4 cm AC 40–300 V 100 A Built-in Transformer Colour Display Voltage Current Power
This compact digital meter is designed for accurate monitoring of parameters in single-phase alternating current networks in both domestic and industrial distribution boards. It operates within a range of AC 40–300 V and measures current up to 100 A, making it reliable for most common installations of 110 V and 220 V. The large colour multifunction display clearly shows voltage, current, instantaneous power, energy consumption, power factor, and frequency in real time. The device is designed for mounting on a 35 mm DIN rail, allowing easy installation alongside circuit breakers in the distribution board. With an accuracy of 1 % ± 2 digits, it is suitable not only for general overview but also for more detailed monitoring of consumption and circuit load.
- Voltage measurement range AC 40.0–300.0 V for standard single-phase networks of 110 V and 220 V.
- Current range of 0–100.0 A with a resolution of 0.01 A allows monitoring of even minor load changes.
- Measurement of instantaneous power in the range of 0–30,000 W, with fine resolution of 0.1 W up to 9,999.9 W.
- Integrated energy consumption measurement of 0–99,999 kWh with automatically changing resolution of 0.01 / 0.1 / 1 kWh depending on the value.
- Power factor display in the range of 0.00–1.00 PF and frequency of 45.0–65.0 Hz for quick network quality checks.
- Built-in current transformer – simply pass the phase conductor through the opening on the right side of the device, eliminating the need for an external measuring transformer.
- Data refresh interval of 2 times per second for almost instantaneous response to load changes.
- Energy counter reset function using a button (SAM CK/RESET) – a long press resets the accumulated consumption and starts a new measurement.
- Independent memory retains the last energy value even after power is turned off, preventing data loss.
- Compact dimensions 8 x 6.4 x 5.4 cm save space in the distribution board, and the plastic housing is ready for standard DIN rail mounting.
- Clear terminals 1–2 for connecting the measured voltage and the opening for the measured conductor make wiring easy for an experienced electrician.
- Suitable for monitoring supply branches, sub-distribution boards, workshop sockets, and individual machines.
- Package contents: 1× digital meter for DIN rail
During installation, the meter clips onto a standard DIN rail in the distribution board, and the measured voltage is connected to the terminals according to the diagram. The phase conductor to the load is passed through the built-in opening on the right side of the device, ensuring current measurement without additional accessories. During operation, the large display simultaneously shows voltage, power, current, power factor, frequency, and accumulated energy, providing an immediate overview of the monitored circuit's behaviour. Thanks to the energy memory, consumption can be monitored over the long term and reset with a single press if needed to start a new measurement. The meter is intended exclusively for alternating current networks of 45–65 Hz; for safe installation, it is advisable to entrust the mounting to a qualified electrician. This device thus represents a practical tool for load control, consumption optimisation, and timely detection of unusual conditions in both domestic and professional electrical installations.
