Shenyang auto-voltage starting control cabinet factory direct

Control cabinet Name: auto control cabinet control cabinet Overview: auto-voltage starting control cabinet with overload, short circuit, phase protection and pump leakage, motor over-temperature protection features and leakage, etc. and complete status display, self coupling transformer voltage starting methods to reduce the impact on power and have a single pump and multi-pump control mode. It can be widely applied to life drainage, industrial control pumps, sewage and other industries. Control motor power range 15-300KW. Key performance indicators: Ambient temperature: -25 ℃ - + 55 ℃ Altitude: less than 2000m, 2000m above need to reduce the capacity of the working environment: no conductive dust, corrosive gases, ventilated; Operating Environment: Power supply: mains, since Network equipment, diesel generating sets; three-phase AC 380V, (- 10%, + 15%), 50HZ Applicable motor: Usually squirrel cage induction motor starting frequency: for frequent starting, recommends no more than 20 times per hour Protection class: IP41 or IP20 environmental conditions: altitude of not more than 2000 meters (over 2000 meters must be derated), the ambient temperature between -25 ℃ --- + 40 ℃, relative humidity less than 95%, non-condensing. Vibration Less than 0.5G.
