Digital Torque-Control Electric Wrench(vertical type) Power supply: 220-240V 50Hz;  Continuous rotation without impact,Website:http://www.dudemachinery.com, much more efficient than hydraulic wrench;  Intelligent torque control system,with fault self-checking function and power-off memory function;  Torque precision:±4%, repeatability: ±1%,double speed design, high/low speed can be shifted freely;  Two ways of torque setting:  - Set the torque manually  - System recommends torque as per bolt parameters;  Human-computer interface. Torque value is shown directly on LCD display. Torque table, is not needed;  Electronic system against over-tighten and the clutch against overload, they can protect driving components effectively;  Intelligent motor-speed control system, it makes the using life of carbon-brush 5-10 times longer than other brand wrenches.ModelMin.torque      (Nm)Max.torque      (Nm)Square      C D      (mm)L      (mm)E      (mm)Weight      (Kg)Non-load      speed(rpm)DTE-62S1206203/4''884302106.427.0DTE-85S1508503/4''884302106.823.0DTE-125S25012501''884382106.819.0DTE-255S35025501''884852108.57.0DTE-390S50039001-1/2''884952109.15.0DTE-500S80050001-1/2''11051021012.54.5DTE-620S120062001-1/2''12852021016.24.0DTE-820S140082001-1/2''12855521017.92.0DTE-1020S2000102001-1/2''128555210182.0DTE-1250S2200125001-1/2''12855521018.51.5
