Load Connections

WARNING
To satisfy safety requirements, load wires must be heavy enough not to overheat while
carrying the short-circuit output current of the device connected to the Electronic Load.
Input connections are made to the + and − terminal block on the rear of the Load. The major
considerations in making input connections are the wire size, length and polarity. The
minimum wire size required to avoid overheating may not be enough to maintain good
regulation. The wires should be large enough to limit the voltage drop to less than 0.5V per
lead. The wires should be as short as possible, and bundled or tied together to minimize
inductance and noise. Connect the wire from the PLUS (+) terminal to the HIGH potential
output terminal of the power supply (UUT). Connect the wire from the MINUS (−) terminal
to the LOW potential output terminal of the power supply (UUT). Figure 2-2 illustrates the
typical setup of the Load to the UUT. When using Model 63208,63209 and 63210 the
distance should be 1 meter for chassis front and 2.5 meters for rear without any foreign object
blocking the vents or the hardware temperature may rise and cause OTP.
