Remark:
1. The ambient temperature of “Permissible Current” is at 40℃, the withstanding temperature of conductor is at 105
℃ according to the condition of the distributed single wire.
2. The permissible current listed as above is suggested to be used under 70%.
3. If the feedback test leads are in need, the level above UL(CSA) AWG24, 22, 20… can be accepted. Besides,
when the load is a capacitive load, please use the twine wire by twisting (+)output test lead with (S+) feedback
test lead. Same way used on (-) output test lead and (S-) feedback test lead.
4. When the current value exceeds above suggestive list, can select more wires used in parallel according to above
list.
