Additional Details
The ST-H-62030-6BF is a 20 kW portable EV charger for 620 V lithium battery systems, built on the ST-H portable charging platform. It accepts a wide AC input — single-phase 110–240 Vac and three-phase 220/380/440/480 Vac (3P+PE) — and delivers up to 30 A across a 240–800 Vdc output window with up to 97% peak efficiency and power factor >0.95.
The unit is fully galvanically isolated between the AC grid and the vehicle DC system, sealed to IP65 in a rugged fan-cooled portable enclosure with an integrated carry handle and an on-board LCD with control buttons. CAN control links to the vehicle BMS, multiple units run in parallel for higher power, and comprehensive protections (input/output OVP/UVP, short-circuit, over-temperature derating, insulation-fault and reverse-polarity detection) plus CE/UL compliance suit high-voltage fleet and field charging. Model code ST-H-62030-6BF (620 V, 30 A, B = 3-phase 220–480 Vac input, F = fan cooling).
