Batteries have had an essential and interesting part of our history and technological advancement.  Going back as far as 250 B.C., batteries provided the main source of energy prior to the development of electric grids and generators.  Improvements in battery technology have made way for major electrical innovations.  From early scientific breakthroughs to devices like the telegraph and telephones right up through today’s modern laptops, mobile phones and even cars, batteries have made all kinds technological strides possible.

Pump Sentry is not a backup pump. It is a combination inverter-battery charger, otherwise known as an uninterruptable power supply (UPS). It is designed to keep your primary pump operating at peak performance during power outages. 

Why is 48V a telecommunications industry standard operating voltage? There are several reasons why this is the case. First, it is considered a “compromise voltage” because this voltage level is high enough to enable relatively low signal loss for transmissions over large distances and yet low enough to be considered a “safe low voltage.”  Most common safety regulations internationally consider levels below 50V to be safe. 

Another advantage of this voltage level is that four 12V batteries connected in series create a 48V DC backup power source, usable in the event of electrical power outage. Many central stations have elaborate arrays of 48V battery banks which may occupy even an entire room.

When trucks first came into popular use, nobody would have dreamed of the numerous specialty applications evolving in the ensuing decades. In those days, only a fraction of homes had electricity. Today one is hard put to find a building that does not, thanks to the existence of the electrical power grid.  The maintenance of the functionality of the power grid is made possible through the capabilities ofutility trucks and their trained operators.

Programmed Logic Controllers are used in many facets of automation control of electromechanical processes. The range of applications has expanded to include managing robotics on automotive assembly lines to controlling chemical sprayers and amusement park rides. Much of PLC circuitry is comprised of relays, and electronic circuit cards, which use DC power as their source.  As PLC’s have evolved, so has the need for them to become mobile for many of their uses. Some of these mobile adaptations include incorporation into:
