Good evening! The G203V drive gets introduced for sale tomorrow.
The G203V is our first attempt at a truly bullet-proof drive. Short it, run it without a heatsink, overvoltage it, miss-wire motors, reverse power supply polarity; throw everything at it save dunk it in saltwater or fill it with metal chips. The worst consequence it will suffer is to replace an internal socketed 20-cent fuse.
The "V" in G203V stands for "Vampire" as in cannot be killed. It incorporates everything we have learned in the last 6 years about how good drives wind up dead.
New features have been added and many annoyances have been removed. The G203V does'nt need external capacitors, the ADJUST tripot is now top-adjustable, the motor stays very cool when stopped, there are no jumper settings at all, The DISABLE input is optoisolated, the STEP and DIRECTION inputs are common-ground, it works with 3.3V logic (no breakout board needed), no "funny" G2xx timing restrictions, power LED and error LED indicators and more.
All the good things have been kept. 33A at 100VDC MOSFETs and 100VDC tested power section, same package size (G201 package) and the same terminal pin-out, the same mounting-hole pattern.
What this means to you if you are a reseller is drive-related service calls, support and drive replacement should drop to nil. The worst case customer service response will be "sort out the problem and (maybe) replace the fuse". The G203V is targeted at never having to replacing the drive.
Caution: The G203V is an entirely new clean-sheet design. Circuitwise the G203V shares absolutely nothing with its predecessors. As such it has absolutely no history. The older G2xx drives have a 20-year design history where every vice has been bred out of them. They simply have no uncovered bad behaviors or surprises left.
The G203V is completely new. I will not feel comfortable with this new design until there are at least 6 months and 5,000 user's experience under our belts.
Pricing is $147USD single, $114USD in 1K quantities.
