Single phase multi-loop energy meter is a 24 loops single phase load energy meter which is intended for intelligent distribution, industrial automation, intelligent security monitoring and control of buildings. The meter is with LCD and RS485. Meanwhile, it adopts SMT Design and manufacture with features as high precision, high reliability, large load, low consumption, smooth error curve, strong anti-jamming ability.
Its functions are as follows:
1. Measuring forward/reverse active power energy, four quadrants reactive power energy, combined active power energy and
two type of combined reactive power energy of 24 loops.
2. Measuring multi-period power energy that is to measure and store total, sharp, peak, shoulder, off peak active/reactive power energy of 24 loops;
3. Storing 12 clearing day energy data;
4. Measuring all kinds of electric parameters instantaneous values (voltage, frequency, current, active power, apparent power and power factor under the same voltage loop.
5. Backing up of CRC check to electricity and parameters.
6. Recycle display and Key display of each loop;
7. With many kinds of electric quantity freezing: the fixed time freezing, instantaneous freezing, agreement freezing,
integral point freezing and date electric quantity freezing.
