mains
Here's the fan I want to use: http://www.nmbtc.com/pdf/acfans/4715ms.pdf
The 220VAC model costs $70 while the 230VAC model costs $17. Can I safely use the 230VAC model in China, where the mains voltage is 220? What are the consequences of using the 230 part in a 220 environment?
**From reviewing your Photo, I misread 60-D-16R as 16Ω but in fact 391 is correct and \$16E\$ is upside down was my misteak
Assuming 33 mA, 390Ω, Vtot = 2.8V*4 + 390Ω*0.033A = 24.07V ...*0.033A= =0.8W
Plan B ( based on poor specs)
- Measuring the Photo the 4LED + 16R , pitch is 60mm and total power @14V= 2.367W/m
- Thus 24W per 10 m minimum. cooler.
- Suggested Supply Tolerance 14V+/-0.2V @ 2A min pref 3A
- 12V will work but dimmer.
In order to smoothen the flicker let's do some calculations.
Second , the decay time between 10ms pulses needs to attenuate 100Hz by at least 20dB or 10:1 in current to be significantly attenuate flicker.
So what value C is needed and at what cost?
You can substitute your values and see if you want to retire it or rewire it with a bridge , **cap, power resistor . have fun and get extra R in case it is too bright or too hot. The resistor must be flame proof and rated for line voltage.
On the right of the diagram swap live and neutral. This is a safety thing although you should never assume neutral is anywhere near earth it is likely to be lower than live. Now your switch is floating on the neutral line not the live.
The drive voltage for your gates has to float referenced on the source connection between Q5 and Q6. Short out R19.
Remove the bridge rectifier it is not needed instead connect D7 to the point that you have labelled in your current diagram as Neutral_230VAc. The ground end uses the body diode of Q6.
Here is a rough diagram component values same as yours
Best Answer
Yes, certainly, provided that it is rated for the 50Hz power used in China.
That voltage is less than 5% low, so you'll just get slightly less air flow and slightly less (acoustic) noise.
