The
Braking hp
rating is dependent on the transistors, diodes, snubbers, and fuses
provided with the module. It is a function of the DC bus amp rating and indicates the
maximum hp that the module is designed to dissipate. Modules are able to provide
full
Braking hp
for at least
60 seconds
. Modules can provide less than full Braking
hp for longer times.
The
Continuous hp
rating is a function of package style, heatsinks, and cooling
fans. This rating is always equal to or less than the
Braking hp
rating. For
applications the following must exist:
Continuous Regen hp rating
≥
Required hp rating * Duty Cycle

Tables 6-1 thru 6-3 list the maximum Watt/Loss generated by each of the listed
Regen units. When installing Regen units in an additional enclosure, consideration
should be given to internal temperature rise. The Watt/Loss rating in these tables is
based upon the maximum regen capability of each unit. Applications that do not
utilize the full capacity may be calculated as follows:
hp*746*5%+100 = Watt Loss
Where
hp
is the average estimated regen horsepower

ERTIFICATIONS
There are presently no certifications for the M3345 Regen Unit. If certification is
required, check with your integrator and/or panel shop for full system certification.
The M3345 is constructed with industry guidelines and safety taken into
consideration. If information is required for certification please contact Bonitron with
your request.

•
Only replace fuses with original type and rating.
•
Due to the current limit control capability, blown fuses typically indicate internal
device failure or severe transient absorption event.
