List of products by brand SLAS
SLAS Switched-Mode Power Supplies (SMPSs) are a series aimed at users seeking reliable, cost-effective power solutions and network accessories. The manufacturer's offerings include SMPSs with various voltage and current specifications, ideal for home applications, simple installations, CCTV, and automation systems. These devices are simple, functional, and designed for trouble-free everyday use.
SLAS – budget switching power supplies and network accessories
SLAS switching power supplies are available in many configurations in terms of power and output voltage. In fact, these are key parameters when choosing any power supply. Popular models include a 12V/3.5A power supply with a standard 5.5x2.5 mm DC plug and a more compact 15V/400mA variant, also with a classic DC socket. The universal connector and voltage standard makes these power supplies compatible with devices such as routers, IP cameras, recorders, monitors, and signal amplifiers. The power supplies operate over a wide input voltage range (most often 220–240V AC), allowing for safe use in home, office, and industrial environments. Their small size and weight make them easy to install and space-saving – chargers should be operational in confined spaces, and that's certainly the case here.
Is it worth choosing a switching power supply?
A switching power supply is worth buying primarily because it's efficient, lightweight, and energy-efficient, while also delivering a stable output voltage even under variable load. Thanks to switching technology, they consume less energy and generate less heat. Home applications and switching power supplies are a truly great match – everything runs quietly, doesn't take up much space, and doesn't heat up like older power supplies. Switching power supply technology itself works by very quickly switching current on and off. Switching power supplies use transistors that switch between states using variable-length control pulses. The voltage is applied to the primary winding of a switching transformer. This is achieved by using a bridge rectifier (usually a Graetz bridge) and smoothing capacitors. The results include greater energy efficiency, stable output voltage, and reliability.
What else should you pay attention to, i.e. the parameters of switching power supplies
Plug polarity indicates which part of the plug is the "positive" and which is the "negative." Most devices have a positive terminal inside, but not all. Connecting a power supply with reverse polarity can damage the device, so check this before purchasing. The optimal cable length depends on the installation location. For desktop equipment, 1–1.5 m is usually sufficient. A DC (Direct Current) plug connects the power supply to the device. The most common standard is 5.5 x 2.5 mm, but others exist, such as 5.5 x 2.1 mm. They differ only in internal diameter, and although they look similar, they don't always fit. It's worth measuring this or checking the device's manual.
