Nord Wave Power Consumption

Postby mmarc » 01 Oct 2012, 14:47

Hi

if Nord Wave power is

115V~25W
50/60Hz
FUSE 300 MA
250V

and local electricity is

220V
50Hz

so maybe I need Voltage Stabilizer and if I need it, how to configure it ?

You need to open the unit, and configure it for 220 VAC. I don't know if the Wave board is the same as other Nord's, so you will need to take a look. Make sure you discharge any static electricity from your body before entering the unit.

I used to have one and if I remember correctly, it has a newer-style power supply (like pretty much everything developed after the Lead 2X) and a case that is very similar to the Lead 2X.

The new style power supplies also have a switch, but may be placed in a mesh that makes it impossible to touch the (mains voltage) parts inside. I don't think the Wave has that mesh, though my Stage 2 did. You can use an isolated screw driver to move the switch (a pen would work too, but an isolated screw driver is safer).

You should change the fuse to a 250V 125 mA SLOWBLOW fuse. It will work fine with the current fuse (since it is already 250V and allows more than the required amount of power to pass), but in some situations the 125 (or 150, if you can't get that) might blow (and protect your Wave) while the 300 mA one wouldn't. Described in a different way: the 125 mA fuse would allow the synth to use about 30 watts of power for a few seconds before it blows, while the 300 mA one would allow it to use just under 70 watts continuously. The Nord power supply is probably somewhere between 20-25 watts, so if that would start using say 60 watts for several seconds there must be something wrong so ideally the fuse would blow and you would know this would happen so you can have a service technician check it out.

Summarized: the heavier 300 mA will project you (the user) just fine, but provides a bit less protection for the Wave.

If you do flip that switch, make sure to put some new sticker near the power connector that states it is now configured for use with 230 volt. Plugging a 230v unit into 115v likely won't damage it (it won't work though), but the other way around will probably damage the power supply (and possible a whole lot more).

You could use an external step-down transformer to go from 230 to 115 volt, but those are cumbersome.

Small tip (might be in the link above): just loosen the screw at the back-left and back-right, because the top panel rotates around those. On the pictures of the Lead 2X you'd see a plastic washer under those screws; my Lead 2X had that, my Wave didn't. But at least you can see in the pictures what screws I mean: the ones with the white, plastic washer underneat them.

thank you for answer! so I got two solutions, switch the power consumption from the inside, in this case I need open the unit or just use converter 220 <-> 110 V

Convert the internal power routing. Leave the fuses alone.

NO NO NO!!!!!

TrueTone550's advice: "Convert the internal power routing. Leave the fuses alone."
is COLOSSALLY BAD!!

...unless, of course, frying your Nord's guts to a crisp is the main objective here.

Nord's which have been set up to run in a 110v environment are fused at 300mA. Nords which have been set up to run in a 220v environment are fused at 125mA. Changing the setting on the internal power supply from 110v to 220v without changing the fuse is exposing the unit to potentially catastrophic damage.

IF THE SWITCH IS TO BE FLIPPED, THE FUSE MUST BE CHANGED.

Going from 220v to 110v, if the fuse is not changed it will likely blow fairly quickly, rendering the unit inoperable, but damaging ONLY the fuse. Going the other way without changing the fuse is asking for a disaster.

Bless,

Pablo

I use 80 WATT Power Convertor Input: 220V/240V 50/60Hz Output: 100/120V 50/60Hz

LOL! I have this image in my mind of the bus in Speed screeching to a halt. Instead of getting on, jadams (possibly wisely) decides not to get on and walk instead (get a convertor). :mrgreen:
