Current-carrying capacity of the integrated braking resistor for MDP90A..-C00

The MDP90A..-C00 power supply module (size 1A) has an integrated braking resistor and is capable of converting an effective regenerative power of 220 W. The regenerative peak energies that can be continuously processed depend on 2 operating conditions.

Observe the following operating conditions during configuration:

• Operating condition 1: operation under continuous duty
• The internal braking resistor can absorb peak energy pulses of 11 kJ. There are no restrictions in terms of delay or wait times after power on or restart.
• Operating condition 2: operation under maximum load
• After the DC 24 V supply is switched on (also after the device is switched on after an operating pause) a general waiting time of 2 minutes applies. After this time peak energy pulses of 25 kJ can be absorbed. If the DC 24 V supply is interrupted during the 2 minutes, the waiting time of 2 minutes after switch-on applies again.
• The connection frequency regulations apply to the restart sequence of the DC 24 V supply.
