Performance Notes (from test charts)

520KV charts note: data are theoretical values when the input voltage is 22V (reference only). At room temperature 25 C with no additional cooling device: current over 41A is non-working zone; 17-41A is short-term (about 10-30s) working zone; below 17A is sustainable working zone.
700KV charts note: data are theoretical values when the input voltage is 19V (reference only). At room temperature 25 C with no additional cooling device: current over 59A is non-working zone; 18-59A is short-term (about 10-30s) working zone; below 18A is sustainable working zone.
