Matsusada Precision is a manufacturer of general power supply equipment.
Here we will describe the correct operation in order to use your DC power supply safely for many years.
Proper installation is important in order to use your DC power supply for a long time.
When installing a rackmount power supply in a rack, avoid securing the unit only on the front.
Be sure to also support it from the bottom with an L-angled support or similar item.
The service life of a power supply drops by half each time the ambient temperature increases by 10 °C.
(The standard service life of a power supply is based roughly on a temperature of 20 °C.）
In order to draw out the full performance of a DC power supply, it is important to make correct connections and ground the unit.
When wiring a connection to a load, it is necessary to consider the current capacity of the wire and the limitation of the length of the output wire due to sensing (0.5 V/lead). Refer to the following table to determine the gauge of the wire.
|AWG||mm3||Max. current (A)|
When connecting multiple loads in parallel, wire them individually such like following image.
For inductive loads, to protect the power supply from load kickback, insert a diode that is rated higher than the output voltage and the output current of the power supply.
Remote sensing is used to compensate if a voltage drop that cannot be ignored occurs in a connector or wiring.
Please pay attention to the following points when using remote sensing.
Connect the power supplies as shown in the figure on the left.
For D1 and D2, choose diodes with sufficient reverse voltage withstand and forward current withstand for the rated output of the power supply.
This kind of connection is also possible.
When using remote control for the power supplies, note that the control potential will change.
When connecting multiple power supplies in parallel, there is always a difference in the output voltage of the power supplies, so it is necessary to balance the current.
* When using master-slave control, refer to the instruction manual for detailed procedures.
