EX Series Operating Manual
Precautions
◆ You must connect the power supplies up to 5 unit included master power supply.
◆ You must set the only one master power supply.
◆ The voltage of slave power supply must be set higher than master power supply's voltage.
◆ It doesn't matter to connect between 1 and 2, 3 and 4, 5 and 6 because of electric connection
inside inside.
◆ Between power supplies, connection wiring length must be 1.5meter less.
And when wiring the connector, it is very important as like inner circuit. So this signal wire
must be lsolated from AC line or flexible line and you must use shield cable for signal cable
and earth Shield that is located in the outer net must be connect to ground.
◆ In other to meet current good balance, each power supply wiring length to DUT must be
same. If the wiring length is not same, you can not set the current balance.
◆ Do not use the 100 percent current usage We will recommend the usage rate up to 90 % ◆ Do not use the 100 percent current usage. We will recommend the usage rate up to 90 %.
Because of current balance, sometimes the power supply can be under OCP trip and
and automatically power supply cut the output and at that time, remained current can rush
to another power supplies and another power supply can be damaged.
◆ The current flowing parallel to the load is total sum of parallel power supplies current.
Therefore, the total amount of current for each power supply current is equal to the sum that
is shown in the display.
◆ The following connection diagram is for connecting of parallel between power supplies and ◆ The following connection diagram is for connecting of parallel between power supplies and
DUT.
