DDS450 series single-phase electronic watt-hour meter adopts special large-scale int-egrated circuit with anti-electricity theft and SMT technology, to make sure the accuracy and reliability of measurement, and has multi functions of anti-electricity theft. This product is suitable for measuring AC single-phase active energy of reference voltage 220/240V and reference frequency 50/60 HZ.
1. Measurement: Measure active energy positively and negatively, and accumulate positively
2. Output: It has functions of pulse output and "" LED alarm indication for power utilization, the indicator lamp for alarming is red.
3. Anti-electricity theft: Measure accurately under current reversed phase, load grounding, current loop short circuit and so on
4. Start: Under reference voltage, reference frequency and COSφ =1.0, when load current is 0.4%lb, the watt-hour meter can start and continuously measure the electricenergy.
5. Creeping: When the voltage circuit is applied 1.15Un, the current circuit breaks, the watt-hour meter output test pulse is not more than one
