About the UVZ-3022
The UVZ-3022 is a 3-phase 22 kW VZ3000 Series Inverter Unit originally mass-produced by Reliance Electric. It may have also been in production with ABB or Baldor Reliance at one point but has been discontinued by all of the original manufacturers. It may be hard to locate, but AX Control still tries to keep the UVZ-3022 stocked.
The UVZ-3022 has a power supply voltage of 200/400 volts. It is UL/IEC/C-UL listed and is in a chassis-style enclosure. It is a separate-type unit. It has an input of 240-350 VDC and 50 A with an output of 0-120 Hz, 0-230 VAC, and 60 A @ 200 volts. It has a 460-700 VDC and 53 A input with a 0-120 Hz, 0-460 VAC, and 60 A @ 400 volts.
There is a front cover that protects part of the faceplate of the UVZ-3022. The cover is protecting two sets of terminals. The first terminal strip is the main circuit terminals. There are six terminals on this strip that are labeled 147 (P), 145 (N), 601(U), 602 (V), 603 (W), and G (E). The second set of terminals also have 6 terminals on the strip. These are labeled IP, RDY, 0 VC, + VC, FR 2, and FR 1. To the right of the front cover on the UVZ-3022 are additional components. There are 5 display lamps that are labeled P/S, RDY, RST, RUN, and COM. There is an LED 7-segment monitor display and a drop number dial. There are 3 communications ports, a PG input port, a control signal port, and a PG output port.
