## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE10148:1` (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/CE10148:1.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

A three-channel DC power supply engineered to provide stable, low-noise power for demanding laboratory and prototyping environments. Featuring two primary adjustable channels and a dedicated high-current 5V output, it serves as a versatile cornerstone for any professional electronics workbench.

Designing complex circuits often requires multiple isolated voltage rails - such as a split-rail supply for operational amplifiers alongside a high-current rail for digital controllers. The GPE-3323 eliminates the clutter of multiple single-output units by providing three independent outputs that can be combined internally for higher voltage or current requirements without external bridge wiring.

### Key Features

- **Achieve higher voltage or current density** through one-touch Series and Parallel tracking modes, allowing the two main channels to function as a single 64V/3A or 32V/6A supply.
- **Protect sensitive prototypes** using the Output ON/OFF switch, which allows you to dial in and verify your settings before applying power to your circuit.
- **Power-hungry control circuits with ease** using the dedicated third channel, which provides a fixed 5V output at a substantial 5A capacity.
- **Maintain precise control** over your parameters with the digital "Set View" function, allowing you to monitor programmed limits in real-time on the display.
- **Prevent accidental set-point changes** during long-term testing or in educational settings by utilising the integrated hardware Key Lock function.
