Sensor-accessible energy meters

Product Overview

Sensor access type power meter is a kind of power meter adapted to electronic transformer or non-traditional transformer secondary signal access, the input signal is analog small signal. It is suitable for metering places that use electronic transformers with outputs complying with IEC60044-7/8 standard.

Intellectual Property Rights

"ZL200820187889.9 Weak Power Sampling Energy Meter" and other 5 other subsidiary patent technologies.

Product features

1, the input signal is analog small signal, the connection point adopts waterproof connector form, avoiding wiring error. At the same time, there is no high-current crimping point, which avoids the possible heating phenomenon in long-term operation.

2、The internal sampling point circuit of the power meter is simplified, canceling the manganese copper shunt resistor or current transformer, voltage transformer and other originals, without the phenomenon of "burning the end of the meter"; 3、Matching the electronic transformer, avoiding wiring errors.

3、Matching electronic transformer improves the safety of primary line.

4、The energy meter can be calibrated separately or together with the electronic transformer, which not only improves the accuracy, but also reasonably matches the two loads.
