Decades ago, the critical electronic components in a race car were the ignition coil and points. Race cars now feature advanced engine management systems, antilock brake systems, paddle shifters, dataloggers, radios, electric pumps, fans, and lights. All components need to be controlled at the correct moment, and all components require circuit protection to prevent damage or fire.

Traditionally, fuses and relays served all of those purposes, but they have many disadvantages like complicated wiring looms, sensitivity to vibration/temperature, and difficult diagnostics.

All of these problems can be solved by using intelligent power management units (PMUs). Our newly developed PMU unit is at the forefront of technology. It provides 16 high current outputs (and use of multiple units if more outputs are required).

One of the main advantages of the PMU is continuous current sensing and self-resetting function if the current exceeds a defined level. All output state, voltage and current information can be logged and transmitted via a CAN bus to dash displays to inform drivers of potential problems.

An additional advantage of the PMU system is the ability to define logic for controlling outputs. This is done with data from analog input channels or CAN bus data, and math operations can be defined for each channel. The PMU is also equipped with LED indicators to show the status of each output.

With use of CAN bus keypads or steering wheel switches, all wiring is vastly simplified and lightened.

Two unique features are the inbuilt accelerometer and gyro for logging and “inertia switch” in case of accident.

TECHNOLOGY

The PMU is assembled according to IPC-S-815A standards to ensure product reliability. The device is manufactured on an automated assembly line with optical inspection, and automated testing (including burn-in).  The PCB material and design, special surface coating and IP65 enclosure ensure reliability even in the harshest environments. Carefully selected components allow for continuous and reliable operation across a very wide temperature range (AECQ-100 GRADE 1 (-40 to +125˚C).

Nice jewelry box
Color: White, Size: 2 Layer, Color: White, Size: 2 Layer
This is a very nice jewelry box. It has two drawers with lots of compartments and can hold a lot of jewelry. I love that it is easy to see inside the compartments and will make it so easy to organize my jewelry. It doesn’t take up much space and looks great on the dresser. I highly recommend this jewelry box!

Excellent organizer
Color: White, Size: 2 Layer
I wanted something to help me with the jewelry I keep in our safe and this works perfectly. I had kept items in their individual boxes, having to open each one to find what I sought. No more. I keep my more popular items in the top tray and I can see them through the glass. Next order items are in the lower drawer and easy to see many at once. The compact size lets it sit in the same form factor on the shelf in the safe. I’m very pleased with it.

“Stylish and Spacious Jewelry Box, but Quality Could Be Better”
Color: White, Size: 2 Layer
The Casegrace jewelry box looks elegant and feels durable with a nice weight to it. The interior is soft and well-organized, with plenty of compartments for rings, earrings, and other pieces. It’s great for keeping jewelry neatly arranged and easy to find. However, the top cover isn’t real glass — it’s more like plexiglass or plastic — and it doesn’t lift open, which was a bit disappointing. The outer material looks nice but feels like it could start to wear or peel over time. Overall, it’s still a stylish and functional jewelry box with good storage space and a clean look, but the build quality could be a little better for the price.

Top tier rotating jewelry box; soft and great quality
This has got to be the most functional jewelry box I’ve ever seen. It’s not very traditional in design and I love that about it. It stands vertically and rotates! Every side is designed differently and constructed to house multiple types of jewelry. I tried to snap a picture of each angle. I like that it has features to keep the jewelry organized too, like the necklaces or bracelets that can be hung on clips/rungs and placed neatly inside a pocket which kind of binds it into place and lowers the chances of it tangling. There’s even a mirror that you can look into when putting your jewelry on. It seems like the box favors rings and necklaces more-so than earrings (which I have most of) but you can get creative and place earrings in the pocket that’s under the mirror flap or inside the drawer. This is definitely worth its value—it does not disappoint! 5/5:)
