Snubber Transistor Kits (M3575TH__, M3575TL__)
The figure below depicts the breakdown of the Enclosed Transistor kit part number.
Enclosed Transistor Braking Unit Status Indicators
Braking units have the following status indicators:
• DC BUS: A green LED that turns on when the DC bus voltage is equal to or greater than 90 VDC.
• ACTIVE BRAKING: A red LED that turns on when the dynamic braking transistor turns on. Note that if this
indicator is on continuously, the AC line voltage may be high. Use an input transformer to reduce the
incoming AC line voltage to the AC drive or consult your local Rockwell Automation - Reliance Electric sales
office for assistance.
Enclosed Transistor Braking Unit Fault Outputs
Enclosed Transistor Braking units have one normally-closed contact (NC) rated at 2 amps, 125 VDC or
125 VAC that opens on the following fault conditions:
• loss of DC bus voltage
• open load
• Overtemperature
• transistor failure
