SureStep Regen Braking Accessories

• Built-in 50W power resistor for more continuous current handling (optional 100W resistor is also available)
• Mounted on a heat sink
• Voltage range: 24–80 VDC; no user adjustments required
• Power: 50W continuous; 800W peak
• Wire connection: 6-pin screw terminal block; 12–18 AWG wire
• Indicators (LED):
  - Green = power supply voltage is present
  - Red = clamp is operating (usually when stepper is decelerating)
• Protection: The external power supply is internally connected to an "Input Diode" in the regen clamp that protects the power supply from high regeneration voltages. This diode protects the system from connecting the power supply in reverse. If the clamp circuit fails, the diode will continue to protect the power supply from over-voltage.
• SureStep Regen Clamp 50W, 24-80 VDC (STP-DRVA-RC-050)
  and SureStep Braking Resistor 100W, 10 ohm, encapsulated (STP-DRVA-BR-100)
• The SureStep Regen Clamp is $92.00 (STP-DRVA-RC-050)
