About IT6720
Compared with other power supplies, IT6720 has the
widest range of voltage and current. The max output
voltage is 60V, the max current is 5A, and the max power
is 100W. You can set multi-groups voltage and current
value as long as the max range allowed. So it can replace
3 power supplies 60V*1.6A / 32V*3A / 20V*5A, and help
you save money.
Example
If you have set the voltage value
with 60V, the max current value can
be set with100(W) / 60(V) = 1.66A,
because the max power is 100W. If
the voltage value is 10V, the max
current value can’t be set with 10V,
only 5V.
