Remarks
|
1. Ripple and noise measurement: Use twisted pair wire, connect 0.1uF and 47uF capacitors at the terminal, and measure under the condition of 20MHz oscilloscope bandwidth; 2. Voltage Accuracy: including setting error and load regulation; 3. Standard configuration of structural size of plugs and wiring, it’s also can be customized. 4. Fuse: For safety reasons, the module input must be connected to the fuse. The recommended specification for WA5P is 1A/250V, WA10P-WA15P is 2A/250V, and WA20P-WA40P is 3.15A/250V. |
