The ICE2QS03G is a quasi-resonant PWM Controller optimized for off-line switch power supply. The digital frequency reduction with decreasing load enables a quasi-resonant operation till very low load. As a result, the overall system efficiency is significantly improved compared to other conventional solutions. The active burst mode operation enables ultra-low power consumption at standby mode with small and controllable output voltage ripple. Based on the BiCMOS technology, the product has a wide operation range (up to 25V) of IC power supply and lower power consumption. The numerous protection functions give a full protection of the power supply system in failure situations. All of these make the ICE2QS03G an outstanding controller for quasi resonant flyback converter in the market.
- Active burst mode for low standby power
- Quasi resonant operation
- Digital frequency reduction for better overall system efficiency
- Quasi resonant operation till very low load
- Active burst mode operation at light/no load for low standby input power (<100mW)
- Digital frequency reduction with decreasing load
- Startup cell for VCC pre-charging with constant current
- Built-in digital soft-start
- Foldback correction and cycle-by-cycle peak current limitation
- Latch-off mode for adjustable output over-voltage protection and short-winding protection

Not a huge fan
Size: 10mm*33m, Color: Blue, Number of Items: 4
I don’t know why I keep accidentally ordering this. I love htvront but this tape isn’t super great for ceramic ornaments. It’s not as sticky as I need.

Holds tape awesome

Durable and functions as needed. Easy to use. Makes getting tape off easy. Wish I would have bought this a year ago when I started ironing on patches to hats.

A great printer with lower pricing
Style: ET-4800, Color: White, Set: FAX/ADF/Print/Copy/Scan
I am quite happy with my ET-4800 purchase. From wirelessly connecting to my Mac to software installation to adding the ink, it was easy to set up. I feel you can't go wrong with this level of ink capacity. It holds so much ink without the bother and added expense of frequently replacing cartridges. I will never go back to a cartridge machine. I don't care who makes it! I've used my printer several times so far, and each time it has done a great job by giving me the colors and clarity that I expected.
This is the first printer that I've owned that wasn't a front-feeder. I wasn't sure how I would like that, but I've found that holding the paper straight and then dropping it into the slot rather than placing it, gives the best result for paper alignment. For my needs, I have only used it one sheet of paper at a time. So if you are wanting to load several sheets at once, your loading experience may be different from mine. But just make sure that you do not load more than 100 sheets at a time, per the manufacturer's instructions. Also, be sure that the movable paper guides are in the correct spots for the size of paper being used, without any buckling.
To date, I have not used the scanner, but it is definitely a feature that I did not want to be without, so I'm looking forward to using it. The display window, though small, is simple to follow along with, and I appreciate that the angle of the keypad can be adjusted. Working with the Epson Smart Panel app gives a bit more flexibility, particularly if you're not right next to your printer and want to check the ink levels or start a printing job. To use the app, be sure that you turn on your printer first and that both the printer and your device are set to the same wi-fi, so that the app can find your printer and you can begin operating it from afar. Once inside of the app, be sure to check out the "Other Features Menu" from the app's homescreen. There is a link to another Epson app that can be used to boost your creativity and streamline layouts for collages, and a colorful guide full of project ideas that outline everything that you need for each project and how to execute them. There's even a feature for sharing what you've scanned and submitting it as an assignment. This is something that you'd want to read more about to see if it is an applicable and helpful addition for you. You can use the search term, "google classroom in epson smart panel app," to find out more.
There is only one downside that I have found at this point. The pull-out paper catching tray in the front feels flimsy. It seems out of place on an otherwise sturdy machine. But so far, I've had no problems with it. I just take my time pulling it out, flipping down the end, folding it back up, and pushing the tray back in. I figure if I baby it a bit, then all should be well. Overall, I really like the Epson ET-4800 as much as my ET-5170. I feel it performs well at an acceptable price point.

Excellent product for the price.
Style: ET-4800, Color: White, Set: FAX/ADF/Print/Copy/Scan
I have had many, many printers over the many years at the business and for home. I honestly think this is the best value for what I need. The eco tank is fabulous. This is the first printer I have purchased with the ecotank. So much better than the cartridges. The quality is good and it was easy to setup and put on the network. I did wait a few months before writing this review to truly test it out and write a fair review. I am pleased. I have had Epson products in the past and do appreciate their quality and affordability.
