## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=DFR0929:1` (comma-separated SKU:qty pairs) and share the link. 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/DFR0929:1.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)

## Description

This industrial-grade 50W high-power step-down module offers a voltage input range of 9-18V and a maximum output of 5V/10A. It has the characteristics of high isolation withstand voltage of 1500V DC or 800V AC, low radiation interference, ripple noise, etc.

With short-circuit protection and input under-voltage protection mechanisms, the converter can be widely used in portable power supply systems on the chassis, railway locomotives, new energy, communications, electric power, industrial control, occasions where input and output are isolated and other industries.

 | Pin | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
|---|---|---|---|---|---|---|---|---|
| Name | FG | +Vin | -Vin | CNT | TRIM | NC | -Vo | +Vo |
| Definition | Shell | Input positive | Input negative | Control foot | Output regulation | floating | Output negative | Output positive |

CNT (control pin): Module on: CNT is floating or connected to TTL high level (3.5~12Vdc); Module off: CNT is connected to GND or low level (0~1.5Vdc)

**Precautions:**

- The power module will generate heat after being energized for a period of time. Please do not touch it with your hands or body, otherwise, it may cause burns.
- Please check whether the wiring is correct before turning on the power, otherwise, it will cause damage to the power supply.
- When testing the insulation withstand voltage between the input and output, please short-circuit all the pins of the input and output terminals respectively and test.
- When the product shell temperature exceeds the specified value, heat dissipation needs to be considered.
