Digital LCD Single Phase Din Rail Electric Meter 5-32A Electronic KWh Meter Features: The meter is fully in conformity with the relevant technical requirements of GB/T17215.321-2008 national standard and the IEC62053 international standard of grade 1 or level 2 single-phase energy meter, which can directly and accurately measure active energy of the energy consumption. LCD display  is  5+1 meter shows the total power consumption. It features high reliability, small volume, light weight, beautiful appearance, advanced technology, and 35mm DIN standard guide rail installation, etc. It has good anti-electromagnetic interference, low power consumption, high precision, high overload, high stability, anti electricity-stolen and long life. This table is suitable for the measurement of rated frequency 50 Hz or 60 Hz single-phase ac active electricity, used for fixed installation indoors, apply to the environment temperature is -25 ℃ ~ 55 ℃, relative humidity is ≤ 95%, and in the air does not contain corrosive gases and avoid dust, mold, salt fog, condensation, insects, etc. Specification: Model: DDS518C Phase number: single phase Type: guide type Display mode: LCD Rated current: 5-32A Working temperature: -25 ℃ ~ 55 ℃ Accuracy level: level 1 (equivalent to measurement error < 1%) Including S0 port 2000Imp/kWh (ti = 80ms) Relative humidity: 95% Size: as the picture Weight: Approx.104g/3.7oz Installation considerations: 1.Installation of Electric Meter required experienced electrician or professionals. 2.Electric meter should be installed in indoor ventilated and dry place, adopt 35mmDIN standard guide type installation, the bottom plate of the electric energy meter shall be fixed to the rigid refractory, non-vibrating wall. 3.The bottom plate of the electric energy meter shall be fixed to the rigid refractory, non-vibrating wall. 4. Electricity meters should be installed in protective cabinets in places where there are filth and potential damages. 5. The installation should be in accordance with the wiring diagram, preferably with a multi-strand copper wire, avoiding the abnormal or burning of the electricity meter because of the bad contact. 6. When the electricity meter is correctly connected to the power grid, the power indicator of the meter is on 7. Electric energy meter should take the lightning protection measures when it is used in the area with more lightning, so as to avoid damaging the electric energy meter by lightning.   The load capacity of the electricity meter is 0.05ib ~ Imax (direct access) Power indication: when the green light on, indicates that  working power supply is normal Pulse indication: when the red light on, indicates that the power pulse is detected When there is a sampling signal, the pulse light is about 80ms Package list: 1 x  Din-rail energy meter
