Logic supply voltage 24 VDC (X13)
The following diagram describes external 24 VDC / max. 40 A power supply, electrically isolated, for example, via an isolating transformer. The required current rating depends on the use of motor brake and number of connected MKD-N drives.
The 24 VDC voltage is internally split into a control supply to power the MKD-C electronics and a supply voltage to power the connected MKD-N drives in case of switched off AC mains power.

Standby power is limited to 750 W at 24 V for both strings. This power must supply all drive modules and the remaining power can be used for motor holding brakes. |
Fusing (such as fusible cut-outs, FA1) to be provided by the user: "Fusing" External power supply and 24 V fusing.
