are you overclocking your antminers ?
maybe im pushing the PSU too hard running it at 2000watt constantly.
The S1's are overclocked to 393/400. But still I'm only running 4 per PSU so at most I'm pushing 1600watt, most likely closer to 1500. |

Just a quick peek at what I am working on for these PSU modular "racks"  |

Shipped a batch of DPS2kBB PSU breakout board bases to MinerSource.net just yesterday!
I will be test printing these racks asap. Stay tuned

Partly because of a multi-point failure of finances (deposit computer errors and slow/non-paying customers) we were delayed about two weeks on ordering materials for the next batch of DPS2K boards. The next round should be available starting in about 4 weeks. We'll open up a (pre)order queue probably sometime next week once we have a better idea of when we'll be shipping.

Nice bro! Shoot me your shipping info, I will toss a case or two in the mail asap. |

RE: cooling the PSUs I just use a $20 3 speed 8" A/C fan per 2 PSU, never had a cooling issue. The fans were on middle setting for >90F ambient summer cooling. Recently down to 'low' super quiet.  I follow the school of thought that pushing is preferred to pulling air for cooling. Compressed air can carry more heat away. (in theory) I also prefer lower tone of fans pushing. One must inspect and in some cases clean the insides of dirt. Some are pretty clean and some have gunk in there... RE: DPS-1600 and DPS-1800 W PSUs I can confirm the 1800 and 2000 work equally. I'd expect the 1600 to also work. I wouldn't mix different watt PSU on a 'combined' 12VDC rail though. YMMV |

Novak and I are working on a design for a control board that'll interface to six or eight of our PSU boards at a time (both the D750 and DPS2K boards, plus whatever we release in the future since they should all have a standard header) for monitoring and control. The current plan is to make the board-end giblets connect to the control base with ethernet cable, so you can spread things out however you want with what lengths of standard cable are available; the control base would tie to a computer through USB. We'll probably write some basic linux command-line software for monitoring and control, possibly with a basic webpage port for displaying status. If everything works how it should, it's a thing that should run off a Pi without trouble. Still in design phase, but more people expressing interest will probably speed that up. We figure on deploying some at least within our own hosting setup to test and mess with, should make it easy to power-cycle miners remotely as well as monitor PSU status and such.

The dip switch on the board, does it have to be on a specific setting

Switch 1 enables internal fan control
Switch 2 enables external fan control
Switch 3 enables external-on function

That depends on you. We typically ship them out with internal fan and external-on enabled. If you don't want to be able to turn it on from an external signal, kill EON. If you want to control the fan speed from an external source instead of the built-in knob, turn that on.

internal fan control will control the pwm fan based on the temp in the psu ?

No. Internal fan will control the PWM fan based on the knob on the board. If you want temp control, you set up a temp measurement and pipe it through the external fan control.

Sidehack is there a 5v out on this board? I am looking to use one to replace my current cointerra machines. the 5v feeds the beaglebone.

Yeah there's two pins on the header labeled 5VO which can source 5VDC up to 2A without any trouble.

Mind showing me where? Don't see em Meaning I have 2 connector. I understand the output. Do I need to split the connection, and where would I get ground from? |

The ten-pin header at the corner of the board. I don't have one in front of me, but it's identical to the header on our D750 boards; in fact, any questions about the operation of the board not specific to attaching fans to the 4-pin headers can probably be answered by reviewing the D750 V0.5 spec doc on the product page on our website.
On the header is a ground pin and two 5VDC pins, all labeled. The 5VDC is available any time the 12V of the PSU is outputting.

I saw it on the spec doc. BTW the link to your 2000w on the homepage is bad, you have it pointed to the local ip instead of gekkoscience.com Can you tell me how I would wire a 3 pin fan instead of a 4 pin? Thanks in advance! |
