The Electronic Load series is a single-channel programmable DC electronic load. It provides various solutions according to your design and test requirements with the optional RS232, USB, RS485 communication interfaces. Constant Current Operation Mode (CC) In this mode, the electronic load will consume a current in accordance with the programmed value regardless of the input voltage. Constant Voltage Operation Mode (CV). In this mode, the electronic load will attempt to consume enough current to control the source voltage to the programmed value.Constant Resistance Operation Mode (CR) In this mode, the module will consume a current linearly proportional to the input voltage in accordance with the programmed resistance. Constant Power Operation Mode (CW) In this mode, the electronic load will consume a power. If the input voltage rises, the input current will decrease and the power P (=V*I) will be maintained at the programmed value.
