Power supply equipment to supply 24V DC to this product
① 24V DC power supply
● Switching power supply (24V DC)
● 24V DC battery
3A 72W or more per MDR
■
A switching power supply is recommended as the DC power supply (24V DC±10%) for drivers.
■
Use a stabilized power supply that has an adequate capacity of 24V DC and 3A or higher
and does not fluctuate due to load variation.
■
If the power supply capacity is smaller than the rated power of the dedicated driver card
multiplied by the number of MDRs to be used, the supply voltage may drop and cause failure or
damage of the MDR and driver card. Be sure to use a power supply with a capacity larger than
the rated power of this product multiplied by the number of MDRs to be used.。 ⇒Refer to P.29
＊When starting multiple MDRs simultaneously, use a power supply with a capacity of 3A
multiplied by the number of MDRs to be used.
■
For the power supply unit, use an isolation type switching power supply compliant with the
safety standard (IEC62368-1). Do not use a non-isolation type power supply for safety
reasons, since it may not conform to the radiation noise regulations.
■
A transformer type power supply cannot be used.
■
Secure a voltage of 24V DC±10% at the power supply terminal of a driver card.
■
The power supply should not activate protection with peak current 20A, 1msec or below.

Following is conditions to comply UL standard
Recommended power supply specification
・Stabilized power supply that isolates between output and input.
・Connect driver cards within a capacity of power supply.
<Cautions>
The installation of over current protection device at primary side in power source might be requested
when using a compliant safety standard which is UL62368-1, IEC62368-1 or CSA C22.2 No. 62368-1.
In this case, install specified over current protection device.
