Dynamic Braking (DB) Hardware Continued
15H Catalog Numbers with an “E” Suffix
These controls are equipped with a factory installed dynamic brake transistor and brake
resistor(s). Size A controls have 400 watts and size B controls have 800 watts of
dissipation. These can provide 100% braking torque for 6 seconds of a 20% braking duty
cycle. Should additional braking capacity be required an optional externally mounted
RGA brake resistor can be used in lieu of the internal resistors. See RGA assemblies.

15H Catalog Numbers with an “ER” or “MR” Suffix
These controls include a factory-installed dynamic braking transistor. If dynamic braking
is required, use an optional external RGA brake resistor. See RGA assemblies.
15H Catalog Numbers with an “EO” or “MO” Suffix
No dynamic braking hardware is installed in these controls. If dynamic braking is
required, an optional RBA assembly or a combination of RTA and RGA assemblies
should be added. The RBA assembly provides up to 4,000 watts dynamic braking
capacity. Should more capacity be required, a combination of an RTA (DB transistor) and
RGA (DB resistor) should be used. Refer to RBA, RTA and RGA Assemblies description.
