I'm working around the clock building MINI's
- Today I'll be installing Belleson super-regulators and setting output voltage.
- Tomorrow the internal microcontroller will be programmed (based on output voltage) and
testing under load begins.
- Shipping begins Friday and I hope to have ALL the pre-orders shipped by mid-December.
Here is a quick pic from my phone:1)
The large E-I core transformer that you see is for the linear charging circuit (which charges the two banks of ultracapacitors).2)
The heatsink on the top of the red board is for the constant-current charging of the linear regulated voltage feed.3)
Microchip on the red board is programmed to run the patent-pending MINI PURE-DC-4EVR (controls the silent switching of the cap banks, monitors cap bank voltage, etc.)4)
Simple on/off via a red-illuminated push-button switch on the front panel (and the "pre-charge" time for the supply when you first plug it into AC power is only approx. 60 seconds).5)
The Belleson SPVR-X linear super-regulators will be attached to the rear next (large heat sink on the back) and offer extremely low noise and output impedance over a wide frequency range. I believe they are actually unrivaled in this regard (or among the very best super-regulators available at this level of output current!). Belleson promised me o'scope plots for those interested in some performance measurements.
The Belleson SPVR-X has no problem with 2.5A continuous output current, and 5A peaks.6)
For those who ordered our custom cable, here is a pic of what it will look like (this one is 3-feet, for a microRendu):
Gold-plated banana plugs that mate with MINI's output posts (if you are making your own cable, you can also
use spades or bare wire).7)
5-year warranty (Parts & Labor)
That's it for now - back to building!
PS: Pre-ordering ends in < 9 hours
