24 V DC/over 200 mA (Operation range: 14 – 28 V DC)
Usable power input plug: Non-polarity type
(5.5 mm outer diameter, 2.1 mm inner diameter, and 9.5 mm long)
Note
Plugging a DC plug into the RM-200M's DC POWER IN terminal automatically switches the RM-200M's DC
power input to this terminal, disconnecting the unit's power supply from the LINK connector.
Be sure to firmly secure the DC plug by fixing the power cable onto the RM-200M's bottom-mounted cable
hook.
If the DC plug is pulled out, the LINK connector takes over the unit's power supply and is connected to the
system power line. This may cause the voltage drop of power supply and increase the current consumption
from the VM-3240VA or VM-3360VA, resulting in the system malfunction.
