ELECTRONIC SOLUTION PROVIDER FOR INTELLIGENT MANUFACTURING 3.2 Connection Before connecting the power cord, observe the following precautions to prevent electric shock and damage to the instrument: 1. Make sure that the power supply voltage matches the rated power supply voltage of the instrument; 2. Make sure the power switch is off. 3.3 Installation 3.3.1 AC Input Connection 3.3.1.1 Single Unit AC Input Connection Single Unit AC Input Connection 3.3.1.2 Multiple Units AC Input Connection When multiple 5kW, 6kW, 10kW, and 12kW units are connected to the grid simultaneously, it is...

ELECTRONIC SOLUTION PROVIDER FOR INTELLIGENT MANUFACTURING Figure 2 Multiple 5kW/6kW/10kW/12kW Units AC Input Connection 3.3.2 Voltage Remote Sense Connection When N38300 is working, due to the parasitic resistance of the wire, the voltage at the load input terminal will be lower than the voltage at N38300 output terminal after the current flows through the wire, which will affect the output accuracy of N38300. N38300 series supports remote sense to compensate the voltage drop. When using remote sense, please connect S+ to load input+ and connect S- to load input-. After remote sense...

ELECTRONIC SOLUTION PROVIDER FOR INTELLIGENT MANUFACTURING Note 1. The sense wires can be red and black wires with a cross-sectional area of 0.5mm² to 1mm². It is recommended the sense wire should be twisted. 2. Voltage compensation for models @ 80V is less than 1.5V. Voltage compensation for models above 80V is less than 5V. 3.4 Power-on Test After N38300 is powered on, please check the device according to the following steps.  Power-on test includes two parts: system self-test and output inspection. 1.
