  4. Heat Bed Relay

    Heat Bed Relay


    This Heat Bed Relay will allow you to run larger heat beds that require more power then your electronics can supply.  This is perfect for the 8.4" x 12.6" Heat Bed, 10" x 10" Heat Bed, 12" x 12" heat bed and even help to heat up your 8" x 8" MK1 or MK2 quicker.


    Connect J2 to one heat bed wire and GND from your power supply.  Connect J1 In to 12v+ from your power supply and connect the other heat bed wire to J1 out, then connect the two small Pre-Soldered wires to your Heat Bed out put of your electronics (D8 for RAMPS)

  7. A4988 Stepper Driver

    A4988 Stepper Driver


    Those are 100% compatible drivers with Pololu schematic diagram and genuine A4988 IC on it, those are not inferior A4984 drivers !!! The A4988 is a complete microstepping motor driver with built-in translator for easy operation. It is designed to operate bipolar stepper motors in full-, half-, quarter-, eighth-, and sixteenth-step modes, with an output drive capacity of up to 35 V and ±2 A. The A4988 includes a fixed off-time current regulator which has the ability to operate in slow or mixed decay modes. The translator is the key to the easy implementation of the A4988. Simply inputting one pulse on the STEP input drives the motor one microstep. There are no phase sequence tables, high frequency control lines, or complex interfaces to program. The A4988 interface is an ideal fit for applications where a complex microprocessor is unavailable or is overburdened. During stepping operation, the chopping control in the A4988 automatically selects the current decay mode, Slow or Mixed. In Mixed decay mode, the device is set initially to a fast decay for a proportion of the fixed off-time, then to a slow decay for the remainder of the off-time. Mixed decay current control results in reduced audible motor noise, increased step accuracy, and reduced power dissipation. Internal synchronous rectification control circuitry is provided to improve power dissipation during PWM operation. Internal circuit protection includes: thermal shutdown with hysteresis, undervoltage lockout (UVLO), and crossover-current protection. Special power-on sequencing is not required. Low RDS(ON) outputs Automatic current decay mode detection/selection Mixed and Slow current decay modes Synchronous rectification for low power dissipation Internal UVLO Crossover-current protection 3.3 and 5 V compatible logic supply Thermal shutdown circuitry Short-to-ground protection Shorted load protection Five selectable step modes: full, 1/2, 1/4, 1/8, and 1/16 Learn More

  9. 12v/29A Meanwell Power Supply

    12v/29A Meanwell Power Supply


    This ultra low profile Power Supply delivers 12 Volts with 29 Amps. This is the ideal Power Supply for most electronic setups. "This Power Supply is a solid 12V power source for your projects!" Product Details Qty. 1 12V/29A 215mm(~8.50") x 115mm(~4.5") x 30mm(~1.25") Voltage select switch 110V - 220V 2 DC Outputs Built-in Cooling Fan 85% Efficiency UL 60950-1 Approved Pro-tip: You can easily mount this unit using Single L Brackets and M4 Socket Head Cap Screws. The fan is temperature controlled. It only turns on when the PSU internals heat up above 50degC and then turns back off once the internals fall below 40degC again. Warning - Be sure to disconnect power before attempting to to switch voltage. Power Supply should always be unplugged while you make the connections and also make sure the shield is in place before plugging the cord into an outlet. Warning - high voltage! Always have a qualified electrician connect this unit. Use at your own risk! Learn More
