Opening it shows a confirmation page with live pricing and stock before anything is added to the cart. - **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/GB-3119-2829-0206:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.) - **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there. - **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description This 6A BEC / Voltage Regulator reduces input voltage down to one of five selectable output voltages. The BEC is highly mountable within the goBILDA® ecosystem thanks to the four hex-counterbored thru-holes on the 32mm square pattern that provide for easy one-tool installation. ### Tech Terms In the world of R/C hobbyists, this component is known as a Battery Eliminator Circuit (BEC) for how it eliminates the need for additional batteries when a project’s components require different voltages. To the electrical engineering crowd, meanwhile, this type of BEC is known by several other names. One is “switching regulator." A switching regulator is more efficient than other regulators, including linear ones. And within the world of switching regulators, it’s specifically named a “buck converter” because it opposes (“bucks off”) voltage from its input. Buck converters themselves are sometimes called “step-down converters” or “step-down voltage regulators.” As the name implies, this sort of voltage regulator specifically regulates voltage down—and not up—from input voltage. ### Tech Tip Incoming voltage (accepted via the BEC’s XT30 input) must be at least 1V above the selected output voltage, set at 3.3 by default. You can change the voltage provided by the BEC’s XT30 output to either 5V, 6V, 8.4V, or 12V by moving a jumper included in the BEC's side. **Note:** To prevent damage to the BEC, ensure that the devices you power with it draw a combined current of less than 6A. When powering motors, take note of their Stall Current. For instance, Yellow Jacket Planetary Gear Motors have a stall current of 9.2A, which makes them incompatible with this BEC. ### Specs | Weight | 34g with Included Hardware | |---|---| | Output Voltage | 5V, 6V, 8.4V, 12V | | Dropout Voltage | 1V | | Typical Efficiency | 83–93% | | Output Current | 6A Continuous (7A Burst) | | Output Voltage Ripple | ≤ 300mVpp | | No Load Current | 10–20mA | | Input Voltage (@5V Output) | 6–30V | | Input Voltage (@6V Output) | 7–30V | | Input Voltage (@8.4V Output) | 10–30V | | Input Voltage (@12V Output) | 13–30V | | Included Hardware | [20mm Length M4 Socket Head Screw](https://core-electronics.com.au/2800-series-zinc-plated-steel-socket-head-screw-m4-x-07mm-20mm-length-25-pack.html) x 4, [M4 x 0.7mm Nylock Nut](https://core-electronics.com.au/2812-series-zinc-plated-steel-nylon-insert-locknut-m4-x-07mm-7mm-hex-25-pack.html) x 4 | | Input Voltage (@3.3V Output) | 5-30V | ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/G/B/GB-3119-2829-0206-1.jpg)
