Product use

DT (S) S238-7 series of three-phase rail-type electronic energy meter is a new product launched by our company, which uses advanced special two-way energy metering digital circuit chip and SMT manufacturing process for the measurement of three-phase AC circuit Active or reactive energy, the counter display, which is characterized by two-way power measurement technology, anti-theft, high precision, high reliability, high overload, low power consumption, light weight, low cost. Using 35mmDIN standard rail installation, in line with DINEN50022 standard. 7 very wide (modulus 12.5m), in line with JB / T7121-1993 standards. Widely used in circuit breaker installation box, complete sets of equipment.
The product is suitable for ambient temperature of 0-40 ° C ~ +75 ℃, relative humidity less than 85% of the conditions used.
The product meets the GB / T17882-1999, GB / T17215.321-2008 standards for three-phase electronic watt-hour meter all the technical requirements.


Product features



Two-way active energy meter, long-term work does not need to be adjusted.

Three-phase power supply, one or two phase power, measurement accuracy is not affected.

Wide voltage, current, operating temperature range.

5 + 1 step counter display or 5 + 1 6 + 1 5 + 2 LCD digital display.


Start

When the rated voltage, rated frequency and power factor are COSФ = 1, the watt-hour meter is active ≥0.002Ib (through transformer connection), no ≥0.003Ib (through transformer connection), active ≥0.004 IB (direct access), reactive power ≥ 0.005Ib (direct access), the meter should be able to continuously measure the power.

Defluction

When 115% of the rated voltage is applied and the current circuit is open, the meter test output should not generate more than one pulse.


Principle and function

Measured three-phase voltage and current through their respective sampling circuit into an appropriate level input to the two-way electrical energy metering special digital integrated circuits, the output and the measured input / reactive power proportional to the pulse signal after frequency division, respectively Driven with / without value of cloth into the motor meter, to achieve three-phase energy metering. Meter with power test pulse and output. The table uses three-phase power supply, in the absence of phase (the lack of phase indicator goes out phase A, B phase, C phase, respectively) can still work properly.
