Hunan Next Generation Instrumental T&C Tech. Co., Ltd. 3.5 Installation Instruction N68000 dissipates heat through the built-in fans. When installing, please make sure there is a gap of at least 20cm between N68000 and other objects for air circulation. The power cord is a 3-core wire with grounding protection. Please use a suitable socket for operation. The power cord also matches your local voltage and plug type. If it is not matched, please contact NGI. 7 NGI l NGI N68000 Series High Power DC Electronic Load

Hunan Next Generation Instrumental T&C Tech. Co., Ltd. 3.5.2 Power-on Self Test Before power-on, please make sure the following. 1) The nominal voltage of the AC input socket should be in the correct range. 2) The power cord is plugged into AC input socket. Warning: The three-core power cord provides chassis grounding. Before operating on N68000, please make sure N68000 is well grounded. After switched on, N68000 will start power-on self test. If no error is found, the LCD screen will display the below CC interface. In case of test failure, please record the error information and contact...

Hunan Next Generation Instrumental T&C Tech. Co., Ltd. ZlA Warning: To meet safety requirements, the load wires should be capable of bearing the maximum current which the load can bear, without overheat. Input connection refers to connecting the DUT to +&- terminals on N68000's rear panel. The major concerns for input connection are the wire diameter, length and polarity. The wire diameter should be big enough to ensure measurement accuracy. Meanwhile exceeding heating may cause safety accidents. It is recommended to use standard copper wire with bigger diameter and less length to ensure...

Hunan Next Generation Instrumental T&C Tech. Co., Ltd. Note: The input voltage range for external programming is 0 ~ 10V. Input voltage below 0V or above 10V may cause abnormal operation or even damage. 3.6.3 Sense Connection N68000 provides two types of sense: local sense and remote sense. User can select sense mode on the screen. ♦ Local sense It is used when the load current is not very high. ♦ Remote sense Remote sense is also four-wire sense. When N68000 is working, it will cause a voltage drop in the leads between the DUT and terminals of N68000, which will affect the voltage...

Hunan Next Generation Instrumental T&C Tech. Co., Ltd. Remote Sense Connection 3.6.4 Low Voltage Test Connection Please refer to the technical data sheet for the minimum operating voltage of each model. If lower voltage at full current needs to be tested, users can connect a DC power supply in series mode to compensate the minimum operating voltage. The DC power supply will provide a fixed voltage to ensure a high test voltage at N68000 input terminal. Low Voltage Test Connection N68000 Series High Power DC Electronic Load
