## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SEN0098-V2:1` (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/SEN0098-V2:1.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

Get this low-power current sensor to monitor your project every second for saving energy or protecting the circuit!

This fully integrated Hall Effect-based linear SC780 current sensor gives precise measurement for both AC and DC currents up to 50A. The thickness of the copper conductor allows the survival of the device at high over-current conditions.

The SC780 can output an analog voltage signal that varies linearly with sensed current.

The input and output are designed as through-hole vias and slots, which allow for soldering thick electrical wires and T-shaped connectors. The polarity of the input power is clearly labeled on the board so users can conveniently solder wires or use metal alligator clips to make the electrical connections.

The current sensor features enhanced heat dissipation and circuit-protection functions, which typically can be applied to scenarios such as motor control, load detection & management, aeromodelling, and robot over-current detection.
