The series connection of two units is available but the master-slave operation is not available.
Read the note as follows:
– To operate in the constant voltage (CV) mode, set the voltage to each unit (set the current to either unit to operate in the constant current (CC) mode).
– The COM terminal of the J1 connector is connected to the negative output terminal. Therefore, do not connect the COM terminal of two units to keep their insulation.
– Do not turn off the POWER switch on an either unit. If so, the cooling fun stops so that PAT-T may overheat. When a current flows through an such overheating PAT-T, its semiconductor may be damaged.
– The models of rated output 250 V or more cannot be connected in series.
