• 4 pin AMP connector on output
• Internally fused on both primary and secondary side
• Toroid transformer for minimal voltage drop and minimal EMI

Includes 1, KITDC1- connector kits

• Provides protection against Back EMF
• Automatically gates on at >49 VDC
• 27 Ohm 100 Watt Resistance
• Connects in parallel with above enclosed power supplies
• Pin-out is same as enclosed power supplies

The SHUNT42V100W can be inserted between the DC power supply and the SmartMotor to monitor the power voltage. If the voltage exceeds the threshold, the shunt gates on to clamp the voltage to safe level.
This is designed for the 42V supplies but it can also be used for 24V supplies.

Includes 2, KITDC1- connector kits

Use with cable CBLDC1
