DIY: Make 50Hz/220VAC motors run under 60Hz/220VAC ***

Postby jackryan » Thu Nov 01, 2007 10:00 pm

A number of you might have purchased abroad certain wavemaker pump motor pumps such as Hydor Koralia, Tunze Wavemakers, and the like from countries such as Singapore or Hong Kong.

In most likelihood, it will run but not operate properly once you plug them into the local Philippines 220VAC / 60 Hz power mains.

The key dependency revolves around the need to make a 50Hz rated motor to run under 60Hz frequency.

Don't despair. There is a workable work-around.

A <-> B <-> C <-> D

where:

A = 220VAC/60Hz mains supply
[your local Meralco outlets]
B = 220VAC to 12VDC converter (3-5Amps)
[regulated is best; this usually costs anywhere from php 600 up]
C = 12VDC to 220VAC 50/60Hz inverter (150watts up rated)
[CDRKing sells them at Php 750]
D = 220VAC/50Hz motor load
[Tunze or Koralia's purchased from HK or Singapore or equivalent]

Happy Reefing!

This works...I did try it to my two tunze's rated at 50HZ...running smoothly upto now...Thanks to Jackryan!

Ooooooh kind of confused pre...how do you know that the equipment isn't working properly?? i've had my skimmer from the states running for a while, the Tunze i bought i just plugged in a couple of months ago...I mean is there a noticeable difference?? Sound?? slow propeller?? is it breaking it by running 60hz?

And with the A<->B etc, do you pick from the A,B,C,D?? or do you have to mix, vice versa?? hehe sorry definitely confused :oops:

TIA!

If it's a 110VAC / 60Hz device, then this will not help you. Better check with Edwin if there is a way to get spare parts for your Tunze locally through him.

for those who want to DYI even the frequency converter, here's a circuit for your reference:

PCB Inverter 100W by IC 4047 + 2N3055

This circuit Inverter input 12V (battery 12V)
to out 220V 50HZ, Eesy circuit because less component to use.
It use IC 4047 (oscillator 50HZ) and
Power Transistor 2N3055 x 2 ,OUTPUT Power 100W.

sir peter yung output niya is still 50 Hz, wala bang output ay 60Hz? this can be great para dun sa mga brownout times, pwede gumamit ng battery ng motor para na 12V para magpatakbo ng airpump or even a powerhead..:D

bro, our electricity here is 220v/60hz, but most pumps from HK or Sing is 50hz. if your pump is 110v/60hz then all you need is a transformer. hth!

i think we have to modify the circuit ang provide a 60Hz oscillator..

para sa 50Hz pala.. hindi ko nabasa yung title..:D
we can still use this circuit to and modify it sa 60V tapos kabit sa battery ng kotse.. hehe!

WHOA?? hehe very confused...i am so lost LoL...anyways sir's what about the US 120v?? what hz do they come with, haven't really had time to check that out...is it doing damage to my equipment plugging them in 110v here sa pinas?? TIA

Bro, while I am not sure what your equipment specs are, what they have in the US should all be rated for 110V/60Hz. Majority of the world uses 220V/50Hz ata, in fact not sure if anyone else aside from say the US and Canada (perhaps Mexico as well???) uses 110V. The only 2 countries that I know of that uses 220V/60Hz are us here in the Philippines and South Korea. I amy be wrong and there might be others so perhaps we could wait for some of the others who are more knowledgeable in this to chime in their 2 cents worth.

sir pugo, question lang po... based on your diagram, where can we get the IC4047 locally... or can you kindly be more specific (MC, LM, etc)?

TIA :D

Sir Jb 50 hz ba inverter sa cd-r king :?: I was there yesterday , the sales lady didn't know if its 50 0r 60hz coz their is no marking in the unit of 300wat inverter but the 150 wat generic meron but I like the 300 watt :wink:

Bro, the CDRKing inverter is okay to go. I have tested two models that they have sold before and they worked with the Tunze pump I got from another member here before (that he got from Singapore).

You must however, ensure that you have "regulator" AC-to-DC 12VAC with the right amperage converter to power that inverter though.

Hope this helps!
