Module current draw information

Post by governor blacksnake » Sat Jul 18, 2015 6:53 pm

This information will find its way to the website and other resources soon. Modules not in this list will be measured soon - I've moved my test equipment to a different room and haven't put the modules onto that power supply yet.

These measurements assume "typical" use with some of the I/O patched up and many of the LEDs lit. Maximum current draw may be slightly higher. All measurements in mA.


Hertz Donut mk2: +98, -35
Piston Honda mk2: +105, -33
Tyme Sefari mk2: +36, -46
Zorlon Cannon mk2: +90, -20
Polivoks VCO: +48, -53
Polivoks VCF: +11, -10
Polivoks VCA/ADSR: +32, -32
Polivoks Modulator: +30, -30
Lider Suboctave: +10, -24

Safe to assume these are approximately "maximum load" type of patches?
i.e., "worst-case scenario" current draw?

Any updates?

How about these:

Black Locust
Malgorithm Mark II
King Slender
Kermit
Double Andore Mark II
English Tear

I did a back of envelope calculation for Kermit in another thread. Can't recall where...

I did some consumption readings on a few of the modules not listed thus far.
The Governor okayed me to publish my findings here.

The +12V readings are important one's so i used a Fluke 175 for this reading.
I applied as much positive CV to practically all CV inputs and had LED's/Modes at their most consuming to get the max +12V power draw.

I've rounded figures to the nearest mA or so.

Double Andore MK2: +150, -80
Malgorithm MK2: +140, -20 (All LED's ON) +110, -20 (ALL LED's OFF)
Kermit: +90, -30
Bionic Lester: +70, -50

The aul ghetto test setup...

Fookin' brilliant. Did you notice any change based on load on the outputs? ie using stackables and sending the outs to multiple modules?

Didn't test that, but there shouldn't be any difference in theory as the audio inputs & outputs are in essence "always on" as opposed to the CV inputs.

1 output multiplied will also just have a voltage reduction and shouldn't impact current in anyway.

Maybe my curiosity for fan-out is for modules in general, but specifically for "my first diy build" modules.

Except for Bionic Lester (+125, -125), I updated modulargrid.

Can you detail the Fluke connection?
Ammeter clamp? Or placed in series?

I emailed asking for the King Slender current draw, and they said
+30, -20.

MG lists the Double Andore MKI as +/- 225.

Is that accurate or has this been updated somewhere?

That's a weird one. I checked the changelog and it was like that for a while.
Analoghaven still sells them and lists the current draw as 150mA.

I updated MG and gave it worst-case scenario to both +12V and -12V even though it's probably only for +12V.

:tu: Thanks!

Just starting my system and was trying to stay below the 90% of maximum rated power that everyone suggests. If the Andore Jr is around 100mA +/- and the Hertz Donut MKIII is similar to the Piston Honda MK III I'll be set.

80% is a better safety factor unless you know all the modules have been spec'd for worst-case loaded scenario (i.e., all blinkenlights on full blast, all inputs active, all outputs active, every jack plugged in, etc).

Well I just noticed postmodular listed it as 225mA:
