POWER SUPPLIES: Variety

POWER SUPPLIES: Variety

• A wide variety of Power Supplies ideal for use in the science laboratory including:
  AC-DC / EHT / EHV / PSSC / Dual mode / Ranger / Lockmaster / Adjustable / Continuous / Variable.

(Wikipedia excerpt: ..."A power supply (PS) is an electrical device that supplies electric (P) to an electrical load. The main purpose of a (PS) is to convert electric current from a source to the correct voltage, current, and frequency to power the load. As a result, (PS) are sometimes referred to as electric (P) converters. Some (PS) are separate standalone pieces of equipment, while others are built into the load appliances that they (P). Examples of the latter include power supplies found in desktop computers and consumer electronics devices.

Other functions that power supplies may perform include limiting the current drawn by the load to safe levels, shutting off the current in the event of an electrical fault, power conditioning to prevent electronic noise or voltage surges on the input from reaching the load, power-factor correction, and storing energy so it can continue to power the load in the event of a temporary interruption in the source power (uninterruptible (PS)).

All (PS) have a (P) input connection, which receives energy in the form of electric current from a source, and one or more (P) output or power rail connections that deliver current to the load. The source (P) may come from the electric (P) grid, such as an electrical outlet, energy storage devices such as batteries or fuel cells, generators or alternators, solar (P) converters, or another (PS). The input and output are usually hardwired circuit connections, though some power supplies employ wireless energy transfer to power their loads without wired connections. Some power supplies have other types of inputs and outputs as well, for functions such as external monitoring and control...")
