Enrgtech stocks an extensive range of exquisite bench power supplies from the leading manufacturers. Read on further to explore the essentials of these devices in detail.
What Are Bench Power Supplies?
Bench power supplies are plug-in devices that offer an adjustable DC voltage range on their output terminals. Typically, they feature a few knobs and a meter of some kind to help set the ideal voltage. Some additionally include current limits for assistance with debugging or testing a new project. In the lab, we have a wide range of bench supplies, from very little to extremely huge! Any of these might provide you with the power you want but check to see whether the supply can handle any special voltage or current demands you may have. The ratings are prominently posted on every supply.
Types of Power Supplies:
The two most commonly used types of power supply are linear and switch mode. Both can be utilized as bench DC power sources.
Operate by converting DC from AC line power to user-selectable voltage or current levels through filtering and regulation. Because the 50 Hz or 60 Hz transformer and related filters are physically bigger, linear supplies are heavier.
- Switch-mode power supplies
The AC line input voltage is rectified and filtered in the same manner at first; the DC is then switched (or "chopped") into high-frequency AC. Switch-mode power supplies have taken the role of linear power supplies in many applications because they are substantially lighter, smaller, and more efficient.
Typical Applications:
- Ordinary laboratory
- Education system
- Industry
- Research areas
- Production platforms
- Workshops.
