Frequently Asked Questions
What is a power supply?
A power supply is an electronic device that converts electrical power from a source, such as a wall outlet or battery, into the specific voltage and current required by a device or system. Power supplies are used in a variety of applications, including electronic devices, computers, and industrial equipment.
What is a charger?
A charger is a device that is used to recharge batteries or other energy storage devices. Chargers typically provide a specific voltage and current to the battery, and automatically stop charging when the battery is fully charged.
What is the difference between a linear and switching power supply?
Linear power supplies regulate the output voltage by dissipating excess power as heat, while switching power supplies regulate the output voltage by switching the input voltage on and off at a high frequency. Switching power supplies are generally more efficient than linear power supplies, but may generate more electrical noise.
What is a USB power adapter?
A USB power adapter is a type of power supply that is designed to convert AC power from a wall outlet into the DC power required by a USB device, such as a smartphone or tablet. USB power adapters are commonly used for charging mobile devices.
What is a portable power bank?
A portable power bank is a battery-powered device that is used to charge mobile devices, such as smartphones and tablets. Portable power banks typically include one or more USB ports for connecting to the device to be charged, and may include additional features such as a built-in flashlight or solar charging capability.
What is a voltage regulator?
A voltage regulator is an electronic device that is used to regulate the voltage of a power supply or other electrical circuit. Voltage regulators can be used to ensure that a device receives a stable voltage, regardless of changes in the input voltage or load. They are commonly used in electronic devices and power supplies to ensure proper operation and prevent damage from voltage fluctuations.
Power Supplies and Chargers for Technical Applications
The Power Supplies and Chargers category on FindLight covers electronic sources used to provide regulated energy to instruments, embedded systems, and portable devices. Engineers and scientists will find solutions for bench testing, integration into OEM designs, and maintaining rechargeable battery packs used in photonics, sensing, and control electronics.
Chargers and Related Power Electronics
Within Power Supplies and Chargers, the Chargers subcategory focuses on equipment for controlled charging of battery chemistries such as Li-ion, NiMH, and sealed lead acid. These units typically manage charge stages (bulk, absorption, float), monitor voltage and current, and incorporate protections against overcharge, reverse polarity, and short circuit conditions.
Available products include compact desktop chargers for instrumentation, modular units for rack integration, and field-deployable chargers for mobile systems. Many Power Supplies and Chargers in this category support wide AC input ranges, selectable output voltages, and current-limiting features suitable for sensitive electronics. Some models also provide status indication, remote monitoring interfaces, or programmable charge profiles to align with manufacturer recommendations for specific battery packs.
Specification Considerations for Buyers
When selecting Power Supplies and Chargers, buyers should first define required output voltage and current, ensuring adequate headroom for startup and transient loads. Verify compatibility with the target battery chemistry and capacity, including maximum charge current, end-of-charge criteria, and temperature constraints. For integration into larger systems, review form factor, mounting options, connector types, and compliance with relevant safety and EMC standards.
Ripple, regulation accuracy, and efficiency may be critical for precision electronics or thermally constrained enclosures. For laboratory environments, consider chargers and supplies with clear metering, protection indicators, and easy access to terminals. If remote control or data logging is needed, check availability of interfaces such as USB, RS-232, or other digital control options.
