Features:  Wide applications: This power supplys can be used suitable for precision debugging, mobilephone maintenance, enterprise factory, electronic maintenance and other uses.  You can change the display style by your like, you can change the display mode between classic style, detailed style and curve style.  2.4inch big screen and the display color supports 15 colors to be freely matched and set, and the color customization switch needv to be turned on to take effect, whcich allows youto see the data more clearly and directly.  Output power setting ranges is 10-740W, when setting the output voltage and current, the device will automatically adjust to ensure that the power dose not exceed the set output power.  The power supplys can be monitored and set on the PC software, you can achieve the basic functions such as voltage/current preset, data group quick call out, calibration fine tuning, brightness setting, voltage and current curve exporting. (Only support wins7 or above)  Multiple protections: The output over-voltage and over-current value can be set when the output voltage/current exceeds the protections value, the power supplys will automatically stop the output to avert the damage to the device.  Double fuse setting and detachable design, which is easy for you to replace in time.  RD6012P-W support connect with the mobilephone and on control it on APP through WiFi , RD6012P do not has this function. This two types all support USB connect.    Specifications:  Material: ABS  Color: white  Type: RD6012P, RD6012P-W (optional)  Display screen: 2.4 inch color LCD display  Input voltage ranges: 7-70.00V  Output voltage ranges: 0-60.00V  Output current ranges: 0-12.0000A  Output power ranges: 0-720.00W  Input voltage measurement resolution: 0.01V  Output voltage setting measurement resolution: 0.001V  Output current setting measurement resolution: 0.0001A(6A ranges) /0.001A(12A ranges)  Battery voltage measurement resolution: 0.01V  Input voltage measurement accuracy: ±(1%+5 digits)  Output voltage accuracy between setting and measurement: ±(0.5‰+4 digits)  Output current accuracy between setting and measurement: ±(1‰+6 digits)  Battery voltage measurement accuracy: ±(0.5%+3 digits)  Automatic cut off current value when recharging: Set by yourself  Output ripple typical: 20mV VPP  Working temperature ranges: -10℃~40℃  External sensors Temperature detection ranges: -10℃~100℃/0℉~200℉  External sensors Temperature detection accuracy: ±3℃/±6℉  Constant voltage mode response time: 2ms（0.1A-5A load）  Constant voltage mode load regulation: ±(0.1%+2 digits)  Constant current mode load regulation: ±(0.1%+3 digits)  Capacity measurement ranges: 0-9999.99Ah  Energy measurement ranges: 0-9999.99Wh  Constant voltage mode response time: ±2％  Max output voltage: (input voltage÷1.1）-2  Cooling fan starts condition: Output current>4A or System temperature>50℃  Cooling fan shut down condition when working: Output current <3.
