Connecting the Load

 

 

 

SHOCK HAZARD Turn off AC power before making rear panel connections.

 

WARNING

 

 

All wires and straps must be properly connected with screws securely

 

 

tightened.

As further explained in this section, the following factors should be considered when selecting wiring to connect the load to the power supply:

•Current carrying capacity of the wire

•Insulation rating of the wire should be at least equivalent to the maximum output voltage of the power supply

•Maximum wire length and voltage drop

•Noise and impedance effects of the load wiring

Wire Size

 

 

FIRE HAZARD To satisfy safety requirements, select a wire size heavy

WARNING

 

 

enough not to overheat

while carrying the power supply load current at the

 

 

rated load, or the current that would flow in the event the load wires were

 

 

shorted, whichever is greater.

 

 

 

 

 

 

 

 

 

Along with conductor temperature, you must also consider voltage

 

 

drop when selecting wire sizes. The following chart lists the

 

 

 

resistance for various wire sizes and also the maximum lengths to

 

 

limit the voltage drop to 1.0 volt for various currents.

 

 

 

Although the power supply will compensate for up to 5V in each load

 

 

wire, it is recommended to minimize the voltage drop to less than 1V

 

 

to prevent excessive output power consumption from the power

 

 

supply and poor dynamic response to load changes.
