Description

Midtronics PSC-550S KIT Fully Automatic 12v 55a Regulated Dc Power Supply & CaseThe Midtronics PSC Power Supply Chargers are designed to offer a reliable and clean power source that can be used for charging and maintaining batteries' state of charge. These chargers are specifically crafted to serve during service reflashing, complex maintenance tasks, or on the showroom floor. When in power supply mode, the PSC has the ability to transform a 120 volt AC line input into a consistent and virtually noise free 13. 4 volt DC output.

The Midtronics PSC Power Supply Chargers are designed to offer a reliable and clean power source that can be used for charging and maintaining batteries' state of charge. These chargers are specifically crafted to serve during service reflashing, complex maintenance tasks, or on the showroom floor. When in power supply mode, the PSC has the ability to transform a 120-volt AC line input into a consistent and virtually noise-free 13.4-volt DC output.

When operating as a battery charger, the PSC can supply a current up to the rated value, effectively charging any 12-volt lead-acid battery that has been depleted of voltage. After the charging is complete, the PSC can detect the battery's condition and reduce the current output, ensuring that accessory loads are maintained, or any parasitic drain is offset.

Features

  • Advanced switch-mode design

  • It provides a cleaner, more reliable power source than using a standard charge

  • Fully-regulated DC output prevents overcharging of the battery and provides precise control to maintain the necessary battery voltage during complex service and reflash

  • Multiple protection features for a long, trouble-free life

  • Reverse battery polarity protection via replaceable fuses

  • Brownout input protection

  • Over-current protection; cycle-by-cycle peak limiting and rated current-limiting to maximize the life of the converter

  • Over-temperature protection

  • Quiet, small, and compact for portability

  • Commercial design and heavy-duty internal components ensure years of continuous use

  • Unique proportional fan control circuit

  • Sets the fan speed directly proportional to the converter's internal ambient temperature

  • Enables the fan to turn on and off very slowly, minimizing unwanted fan-starting noise

  • High-quality, detachable cables for easy field service

  • Optional protective carrying case for storage or during use

Very nice shelves they look great up and were easy to install. Same color shown in picture. They seem very sturdy on the wall and I love the look of them. They are light weight and a good size just a little plunder 40 inches. Good quality for the price. I'll be buying again.

Decent shelf but could be improved upon
Color: White, Size: 31.5"L x 8"D, Set of 2
Not bad but could be a little more sturdy. We used longer and a little larger screws to try to make it better and that did help but it still has a little wobble in it. It will serve the purpose for me in my bathroom. They look nice except it would be nice if they would include some of those little covers to go over the screws in the bottom of the shelf so you wouldn’t see them. They really show up on the white shelves.
