OVERVIEW

CV/CC Crossover Characteristics
Background
T3PS power supplies automatically switch
between constant voltage mode (CV) and constant
current mode (CC), according to the load
conditions.
When the current level is smaller than
the output setting , T3PS operates in
Constant Voltage mode . The C.V.
indicator on the front panel turns green.
The Voltage level is kept at the setting
and the Current level fluctuates
according to the load condition until it
reaches the output current setting.
C.V.
When the current level reaches the
output setting , T3PS starts operating in
Constant Current mode . The indicator
on the front panel turns red (C.C.) The
Current level is kept at the setting but
the Voltage level becomes lower than
the setting, in order to suppress the
output power level from overload.
When the current level becomes lower
than the setting, T3PS goes back to the
Constant Voltage mode.
