 SECO DC DRIVES SECO AC/DC Drives Bronco II - Washdown

Bronco II Washdown Duty

A new standard in adjustable speed DC Drives
Specifically designed for food processing and other
industries where the motor and control are constantly
exposed to high pressure washdown to maintain
cleanliness.
The Bronco II Washdown Duty DC Drives convert single
phase AC line voltages of either 115 of 230 VAC to
variable DC for armature voltage speed control of
permanent magnet or shunt wound DC motors from
1/4 to 2 HP.
• Rugged
• Reliable
• Versatile
• Accurate
• Economically priced

Listed

Listed for use in Canada

The white enclosure of the washdown Bronco II is FDA

approved and meets NEMA 4X.
• Totally enclosed
• Cast aluminum
• Epoxy coated
• Gasketed cover Proven Danaher Motion Dependability
• Stainless steel captive screws • Full wave power conversion circuit with 2 SCR’s and 3 diodes with NEMA K
configuration allows cooler motor operation.
• IR compensation improves speed regulation in armature voltage feedback mode.
• Control relay with 3-wire start/stop circuit prevents automatic restart after power
outage for increased safety. (May be reconnected for line start operation if required.)
• Full two year warranty.

For AC motors, the Bronco VFD

line is available. Consult factory
or visit our website for details.
