Optimized for medium frequency (<l kHz) and low turn-off losses

High reliability

High electromagnetic immunity

Simple control interface with status feedbackAC or DC supply voltage

Suitable for series connection (contact factory)

The output of the analog signal is a continuous waveform, according to the size of the instantaneous value, directly acting on the load, such as the computer sound card output, the waveform is as follows:

The output of the digital signal is high and low, and the load side needs a digital processing circuit to further convert the received pulse into the required signal

To add or replace a memory module, do the following:

1. Save your work.

2. Shut down the laptop and close the display.

If you can't determine whether your computer is turned off or in sleep mode, press the power button to turn your computer on first. Then by operation

8. Lift the hard drive cover to detach it from the laptop (2).

9. If you want to replace the memory module, first remove the existing memory module:

a. Open the fixing clips (1) on both sides of the memory module.

Memory modules tilt upward.

Note: To prevent damage to the memory module, hold only the edges of the memory module. Do not touch the components on the memory module.

b. Hold the edge of the memory module (2) and gently pull it out of the memory module slot.

Hold the edge of the memory module (2) and gently pull it out of the memory module slot

Place the removed memory module in an ESD package to protect the memory module.

10. To insert a new memory module, do the following:

Note: To prevent damage to the memory module, hold only the edges of the memory module. Do not touch the components on the memory module and do not fold them

The memory module is bent.

a. Align the notch edge (1) of the memory module with the latch of the memory module slot.

b. When the memory module is at a 45 degree Angle from the surface of the memory module box, press the memory module (2) into the memory module slot until it snaps into place

Take your positions.

c. Gently press memory module (3) and exert force on both sides of the memory module until the fixing clips are in place.

Gently press down on the memory module (3) and exert force on the left and right sides of the memory module at the same time until the retainer clips snap into place

Note: To prevent damage to the memory module, do not bend the memory module.

11. Align the latch (1) on the hard drive cover with the corresponding slot on the laptop.

12. Close the hard drive cover (2).

13. Fasten the four screws (3) on the hard drive cover.

Tighten the 4 screws on the hard drive cover (3)

14. Replace the battery.

15. Lift the right side of the laptop up, and then reconnect the external power supply and external devices.
