As all we know,there are various kind of standard for power supply to match different demand,do you really understand your current power supply which standard it is?

There are 3 standards:A,B,C in our company

Here PEOVG would like to analyze components of the best A standard:

1 400V High Voltage Capacitor:6000hours lifetime (High frequency low resistance for low ripple and high stability)    

2 Heat sink of AC Part (AC part and DC part has separate heat sink, which meets safety certification standard.)

3 AC to DC Transformer

4 Heat sink of DC Part

5 Electrolytic Capacitor (High frequency low resistance for low ripple and high stability)

6 Buzzer Siren:Switch ON or OFF by yourself

7 Rectifier Bridge

8 Varistor for Anti-thunder

9 EMC Magnet Ring:Filtering and Eliminating the interference

10 Thermistors for Overheat protection

11 PTC Recoverable Fuse for over current protection (1.35A)

12 Filter Electrolytic Capacitor to reduce ripple factor

13 Cement Resistor for current content voltage charge (Heat resisting and good heat dissipation)

14 MOS Tube:electric supply to UPS Switch immediately,no delay (Electronic automatic switch)

15 Output Voltage 12-13.8 VDC adjustable,AC Input:100-265V

16 UPS Connecting Cable (Anti-reverse connection design for better protecting the devices.)

17 Acrylic Cover:to protect circuit and isolation of high voltage hazard

Hope the above info help you know power supply better,so does your power supply meet safety certification with standard safe distance?

The power supply just like the heart of the people,it effect the whole project surely if it’s high ripple,bad filter interference,unstable power,please pay more attention and choice the right item.

If you have any technical question of power supply,our team are happy to communicate with you,just write to sales（at）peovg.com
