Notes
|
1. All parameters NOT specially mentioned are measured at 120V/220VAC input , rated load and 25℃of ambient temperature.
2. Tolerance: includes set us tolerance, line regulation and load regulation .
3. The power supply is considered as a component that will be operated in combination with final Equipment. Since EMC performance will be affected by the complete installation, the final equipment manufactures must be-qualify EMC Directive on the complete installation again.

4) Suggested wire diameter: Input 0.75-2.5mm2; Output: 0.5-2.5mm2
5) Please make sure you connect these correctly otherwise your product will not function correctly and could be damaged.
6) Note: Any other requests we can customized.
What do you mean by constant voltage?
|
Constant voltage' refers to the ability to fluctuate output current to maintain a set voltage.
Constant voltage can be used for applications where the workpieces do not have flat surfaces, e.g. crossed wires,
and where the resistance varies significantly, and for extremely short welds (less than 1 millisecond).
