◎
Please adjust the output voltages to the required value before wiring the output modules. The voltage difference among output
modules should be minimized that less than 2% is required.
±
◎
All wirings should be properly connected before turning on. The power supply can not be hot swapped.
◎
Please connect the output terminal of each output module in parallel first and then connect to the load as shown in Figure 3-7.
Don't connect to the load separately.
3.13 Parallel Operation
◎
MS-210, MS-300 and MS-360 are allowed to work in parallel.
◎
Only same output modules adjoining one another inside the same power supply are recommended to connect in parallel.
◎
The total output current should not exceed 90% of the sum of rated currents.
For example: MP650-2C2CO-1
Parallel code "1" means that the two MS-300-2C(5V/50A) located at SLOT 1,2 & SLOT 3,4 should be connected in parallel and the
maximum output current is 90A [(50A+50A)*0.9].

3.14 Series Operation
◎
Higher output voltage can be acquired by using MS-75, MS-150, MS-210, MS-300 or MS-360 in series connection.
◎
Only output modules with the same output wattage and adjoining one another are recommended to connect in series
◎
Output current for series connection should not exceed the smallest rated current of all series connecting modules.
◎
The difference in rise times of individual output module will lead to steps/stairs like turn on.
◎
The output voltage after series connection should be less than 60Vdc [the requirement of SELV(Safety Extra Low Voltage) of IEC60950-1].

(3)Connecting an additional 100K potentiometer to PIN CN7-6, PIN CN7-7 and PIN CN7-8 will provide an adjustment for the
Ω
output voltage in a range of -5% to +5% of the rated voltage (ex: -3%, +2.5% and etc.)
Note The remote margin V program function cannot be used when units are connected in parallel
