Taking a look at the Zivan chargers. They have a range of chargers, and have been in the business of supplying EV conversions for a long time.
The literature doesn't explicitly say these chargers are power factor corrected. I've heard they aren't. They can be modified to support different charging algorithms. Only one model (NG3) supports either 120 volt or 240 volt. In order to use the public charging networks, as well as (in the US) plug into any wall outlet, the charger must support both voltages. Hence, it's only the NG3 that's suitable for use in the U.S.
The models are:
NG1 - High frequency Battery Charger NG1 Single-phase 115 VAC (230 VAC Available)
NG1 12-50 12 V 50 A 60 A 320-650 AH
NG1 96-7.5 96 V 7.5 A 9 A 40-80 AH
NG3 - High frequency Battery Charger NG3 Single-phase 230/115 VAC
NG3 12-100 12 V 100 A 120 500-1000 AH
NG3 144-15 144 V 15 A 18 75-150 AH
NG3 312-7 312 V 7.5 A 9 50-100 AH
NG5 - High frequency Battery Charger NG5: Single-phase 230 VAC = FA Three-phase 208 VAC = FF Three-phase 440/480 VAC = GC
NG5 24-100 24 V 100 A - 500+ AH
NG5 144-30 144 V 25 A 30 A 125+ AH
NG5 312-14 312 V 12 A 14 A 60+ AH
NG7 - High frequency Battery Charger NG7 Three-phase 440/480 VAC
24 V 100 A - 500-1000 AH
NG5 120-30 120 V 30 A 35 A 150-300 AH
NG9 - High frequency Battery Charger NG9 Three-phase 440/480 VAC
NG5 24-100 24 V 100 A - 500-1000 AH
NG5 120-30 120 V 30 A 35 A 150-300 AH
NGTOP - High frequency Battery Charger NG Top Three-phase 400 VAC - NOTE, this one is mounted in a roll-around cart apparently meant for lab rather than on-board use
NGTOP 24-200 24 200 - 800– 2000
NGTOP 96-120 96 100 120 600-1000
