Appendix 1 Recommended Braking Unit and Resistor
1. Megmeet provides four specifications of braking units, they are MDBU-4-90, MDBU-4-132, MDBU-4-200,
MDBU-4-280. Refer to the braking unit User Manual for details.
2. The drive of 75kW or below have internal brake units, without the need for external. For 90kW and above
models, we need external brake unit. The specifications of drive, braking unit and braking resistor are shown
as the following table, for other specifications please contact megmeet engineer. The following table is only
our recommended values, specific configuration need engineer to calculate according to the system
requirements.
