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/ADA3624:1.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 **Mini Power Meter with Voltage, Current, Watts, mAh & mWh Display** (whew that is a mouth-full) is a lot like the [USB In-Line Voltage and Current Meter](https://core-electronics.com.au/usb-voltage-meter-with-oled-display.html) we carry but can be used with a wide range of voltages (not just USB connections). Measure the working voltage and current output for any project with this really fancy power meter. This power meter has a small LCD display that shows off voltage, watts, amps, and mAH and instantly reads the numbers out for testing devices, such as chargers, cables, and cell phones. There are a few nice extras in this very fancy monitor, such as showing the ambient temperature and calculating the cumulative Watt-hours and milliAmp-hours over a running time. Basically it's an all-in-one power management solution that doesn't require any calculation or data logging on your part. You can have it self-power from the power source it's measuring (it has a quiescent of about 20mA and requires at least 3V), or you can power separately from a JST connector or power-only micro USB socket. ## Comes with - 1 x 2-pin JST Connector - 1 x NTC Temperature Sensor Technical Details **Revision History:** - As of June 23, 2020, this power mini kit no longer comes with positive and negative alligator clips, but now includes an NTC temperature sensor. **Specifications:** - **Input/output interface:** 20 A large current screw terminal - **Voltage range:** 0.00 V ~ 150 V ± 0.05V - **Current range:** 0.00A ~ 20.0 A ± 0.05A - **Capacity range:** 0 ~ 999.999 Ah ± 0.01 Ah - **Power cumulative range:** 0 ~ 99999.9 Wh ± 0.01 Wh - **Power range:** 000.00 ~ 2999.99 W ± 0.01 W - **Impedance range:** 1 ~ 999.9 ohm ± 0.1 ohm - **Temperature range:** 0 ~ 99 C ± 1 degree C - **Timing maximum time:** 999 H 59 M 59 S ± 1S - **Small current standby alert threshold parameters:** < 2W / 0.5 H - **Small voltage power supply requirements: measuring**: < 5V - When voltage within range of 4 ~ 30V DC sensor is self powering - For low voltage measurements, please supply independent power supply interface - **Measurement rate:** 0.5 times per second - **Over-voltage over-current set the alarm mode:** display warning interface to alert users - **Over-voltage alert set range:** 1 ~ 300V **Under-voltage alert set range:** 0 ~ 149V - **Current alert set range:** 0.2 ~ 100A - **Product size:** 48mm x 29mm x 22 mm - **Quiescent current:** < 20 mA - **Working temperature:** -10 ~ + 60 degrees Celsius - **Working humidity:** 10 ~ 80 % RH - **Working pressure:** 80 ~ 106 kPa Product Dimensions: 47.5mm x 28.5mm x 26.8mm ### Documents - [Datasheet](https://core-electronics.com.au/attachments/uploads/3694.pdf) ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/v/i/videoframe_4455.png)
