DDS3666 DTS3666
YONY
1. General
DDS3666 series single-phase electronic type watt-hour meter adopts the advanced SMT process and solid-state integrated circuit technology of ultra-low power consumption, it is used to measure the active electric energy of single-phase AC 50Hz, all technical indexes are in conformity with IEC62053-21-2003,GB/T17215.321-2008 Electricity metering equipment (a.c.) – Particular requirements - Part 21: Static meters for active energy (classes 1 ) on single-phase static watt-hour meter.
2. Functions and characteristics
2.1 Stable measuring accuracy, general speaking, it would be free from effect of frequency, temperature, voltage or high order harmonic. After leaving the factory, it is unnecessary to make further regulation to the complete machine, it is allowable to prolong the verification period, which sharply reduces the testing and inspection work of power department, it has obviously advantage in reliability when comparing with other similar products.
2.2 Bi-directional measuring function, it is able to measure out the forward and reverse active energy accurately, and the reverse active energy would also be reckoned in forward value.
2.3 It is able to reserve the data of electric quantity permanently without help of standby battery.
2.4 The register will be driven by single chip directly, preventing pulse-loss phenomenon during power on or off, which guarantees consistency of meter reading data and register indicating value, avoids unnecessary dissension due to inconsistency of data.
3. Specifications and main parameters
3.1 Specification & model
4. Installation and connection
4.1 Outline and installation dimension drawing
4.2 Wiring diagram
