Stepper drive, 3 phase 24~100VDC/18~80VAC, 1.4~8.0A.
Three-phase stepper drive, 24-100 V DC or 18-80 V AC input, output current 1.4-8.0 A.
Overview
The DW3880 is a three-phase stepper drive, accepting either 24-100 V DC or 18-80 V AC directly, with the same 1.4-8.0 A output current range as the DW3580 in this catalogue.
A three-phase stepper motor and drive pairing - such as this drive with this catalogue's M3576T015-8 - runs a finer step angle than the more common two-phase arrangement for the same physical motor size, at the cost of needing a three-phase-specific drive rather than the wider range of two-phase drives elsewhere in this catalogue. The two aren't interchangeable: a three-phase motor needs a three-phase drive, and vice versa.
The extra voltage headroom over the DW3580's 24-50 V matters most on a longer axis or higher step rate, where a stepper motor's winding inductance limits how fast current can be re-established and torque falls away as speed rises - more supply voltage keeps torque up further into the speed range on the same motor.
For the same current range at a lower input voltage, the DW3580 in this range covers 24-50 V DC only.

Questions
Can I run a regular two-phase stepper motor off this?
No — a three-phase motor needs a three-phase drive and vice versa. The two aren't interchangeable, so this is specifically for three-phase steppers, not the two-phase motors most of this catalogue's drives run.
Why would I go three-phase instead of the more common two-phase setup?
A three-phase motor/drive pairing runs a finer step angle than the more common two-phase arrangement for the same physical motor size — the tradeoff is needing a three-phase-specific drive rather than the wider choice of two-phase drives elsewhere in this catalogue.
Which motor is this actually meant to pair with?
This catalogue's M3576T015-8.
Can I feed this from an AC transformer secondary directly?
Yes — it accepts either 24-100V DC or 18-80V AC.
