Note: Please refer to the recommended wire gauge selection table in the appendix.
6.1 Load Wire
Load wire is not included among N39200 series standard accessories. Users need to
prepare load wire. Please refer to the follow requirements while selecting load wire.
1. The maximum allowable current of wire.
2. The insulation level of wire should not be lower than the maximum output
voltage of the power supply.
3. The maximum wire length and voltage drop.
4. Noise and impedance effects on the load wire.
6.2 Maximum Allowable Current
The following two factors should be considered when selecting the wire gauge.
1. The wire should be thick enough to avoid overheating when carrying rated load
current or load short-circuit current. The greater shall prevail.
2. The wire gauge should be selected properly to minimize the voltage drop on each
wire and to prevent excessive output power consumption of the power supply, which
affects the load regulation. Although N39200 series adopts remote sense to
compensate the voltage, it is still recommended to minimize the voltage drop.
6.3 Connectors
N39200 is supplied with two 2-pin connector and two 4-pin connector for connection
between wire and N39200 output.
Please do not connect wire directly to N39200 output, which is easy to loose. The
2-pin connector or 4-pin connector should be used for connection.
6.4 Effect of Noise and Impedance
In order to reduce noise or radiation, the load wire and the remote sense wire should
be twisted pair. The wire length should be as short as possible. Shielded wires must
be used in high noise environments. The shielding part is connected to chassis
through the grounding screw hole on rear panel.
Note: Please refer to the recommended wire gauge selection table in the appendix.
