Resently I discovered the Phoenix T81 sepex controller (800+80a - 96v) by Elektrosistem (www.elektrosistem.com/UK/i-tesep.html). Still waiting to hear back pricing from their US distributer in NC. They also have a smaller T51 (500+50a - 96v) which is smaller footprint than the Zapi SEM-3 but same capacity. These also don't requre directional contactors. Phoenix T51 96v 500+50a 10.16" x 6.25" x 4.10" 10 lb Phoenix T81 96v 800+80a 14.65" x 6.25" x 4.10" 13 lb
Same manufacturer also sells some high-power series controllers with regen braking (for 4 terminal motors): IMC 41 96-144v 400a 8.40" x 7.19" x 3.75" IMC 61 96-144v 600a 8.40" x 7.19" x 3.75" IMC 81 96-144v 800a 15.23" x 7.19" x 3.75" IMC 101 96-144v 1000a 15.23" x 7.19" x 3.75" Chris Tromley wrote: >They use 96 V, 500 A controllers. >(Zapi controller, Kostov motor, I think.) > Is it fair to assume a 96V sep-ex road EV would have similar > performance to a 96V series setup?
