Ac Input Cord; Load Wiring - Ametek Amrel PLA Series Operation Manual

AC INPUT CORD

WARNING
JJJJJJ
The AC input cord is the disconnect device for the electronic load. T he plug must be readily identifiable to the
operator. The input cord must be no longer than 3 m (9.84 feet).
The AC input cord we recommend is specified in Table 2.3, "AC Cord Specification". If you require a special cord, call
our sales representative.

LOAD WIRING

To select wiring for connecting the load to the electronic load, consider the following factors:
•
Insulation rating of the wire
•
Current carrying capacity of the wire
•
Maximum load wiring length for operation with sense lines
•
Noise and impedance effects of the load lines
CURRENT C ARRYING CAPACITY: As a minimum, load wiring must have a current capacity greater than the output
current rating of the power supply. This ensures that the wiring will not be damaged even if the load is shorted. Table 2.4
shows the maximum current rating, based on 450 A/cm², f or various gauges of wire rate for 105C operations. Operate at
the maximum current rating results in an approximately 30 C temperature rise for a wire operating in free air. Where
load wirin g must operate in areas with elevated ambient temperatures or b undled with other wiring, use larger gauges or
wiring rated for higher temperature.
