Wattvarmeter D343 (D 343, D-343)
Wattvarmeter D343 - ferrodinamicheskoy panel meter with a direct-reading system designed for measurement of active and reactive power in three-phase three-wire AC circuits 50Hz at the uniform and non-uniform load phases.
Accuracy class - 2.5.
- 0 - 800 kW;
- 0 - 800kVar.
The size of the front panel - 160 × 160 mm.
Structurally, watt meters D343 constructively arranged in a rectangular plastic box for flush mounting.
D343 devices are used in ambient temperatures from -40 ° C to +50 ° C, n relative humidity to 95% (at 35 ° C).
Positioning and mounting D343
Wattvarmeter D343 are designed for flush mounting on vertical or horizontal panels (panels) made as of the magnetic and non-magnetic materials.
When installing the D343 should adhere to the following rules:
- Installation of equipment should be made carefully, without distortions;
- Fastening vattvarmetrov D343 panel must be rigid and not create additional stress;
- Wattvarmeter D343 at installation should be located away from sources of strong magnetic fields with a strength greater than 0.4 kA / m;
- Appliances intended for inclusion in the network with a voltage of more than 650V, mounted on insulators of reach to touch.
The manufacturer guarantees that the device D343 technical requirements under normal use, storage, transportation and installation. Wattvarmeter D343 compliant, ensuring the safety of life, health, consumer and environmental protection.
