CCTV dc power supply units in Sri Lanka allows surveillance systems to manage the power to multiple CCTV cameras using a central unit. It is also known as AC-DC Converter Transformer for CCTV. The central power supply most commonly installed near the dvr unit. This central power supply unit helps to distribute power to many cctv analog and IP cameras in Sri Lanka at ones without requiring individual power supply units. Kumarasinghe Radio Institute have many branded power units including single output, 4 port and 18 port outputs which all are available in retail and wholesale quantities in our shops in Pettah. When you are using a switch mode power supply it is efficient and safe to provide the correct voltage and the proper current according to the project. It is recommended to to use a power supply with 80% of its maximum capacity to avoid any overload problems. Usually the power requirements for cameras are listed on the label or in the installation manual, find the power information in W (watts). Most branded cctv cameras in Sri Lanka like Hikvision, Uniden, Logitech, Netgear, Dahua, ajhua, hivison, avtech can operate with with a 10% variation in power. However night vision and other functions might bet effected including picture clarity if the power is lot low. This is mostly due to low currents not transferring over long rage using twisted twin or tt wire. It is important to not cross polarities, this might results in damaged to both cctv cameras and all equipments connected, so make sure to read the documentation provided with the devises in order to connect them properly. The metal housing provides protection and heat distribution. Most dc power supply unit Sri Lanka are indoor use only they can not operate at him humidity areas as well. Some comes with surge protection and individual fuse for each output. Led dc power supply units, Industrial Automation, Stepper Motor, Peltier Cooling Systems, Robotics supply units in Sri Lanka are bit different in housing and protection capacities, some comes with device surge protection, Shortage Protection, Overload Protection, Over Voltage Protection and stops electromagnetic interference. Maximum output power of all power supplies range from 130.9W, 2.0W, 105.2W, 10W, 100W, 400W, 130.9w, 120W, 105W, [email protected]; [email protected]; [email protected]
Dc 5 Volt power supply in Sri Lanka are made with small transformer circuit are available retail and whole sale in our shops in Pettah. These 5V power supply used for
powering CNC electronics that includes relay boards and breakout boards that runs on regulated power. Some Raspberry Pi 3D Printers use 5V power supply in Sri Lanka. These are commonly known as step down converter or buck converters. Some Dc 5 Volt power supply have positive (+) and negative (-) terminals. These usually comes in printer LCD displays and some mini digital audio amplifier boards or DIY mini boards with dual channel power outputs. Some RC LiPo Chargers use 5 Volt power supply. Low powered led circuits in sri lank use dc 5 Volt power supply that powers op-amp, a transistor and a couple of resistors. Some home automation and industrial automation circuits use 5v psu, arduino servo motors, ham radio transceivers use them as well.
DC 24V 2A 5A 16.7A Power Supply in Sri Lanka comes in from 400W to lower power out put range. These 24V power supplies are used for LED light installation in commercial building and retail spaces. Low Voltage LED Strips and Linear LED Fixtures, 24V Wall Washers, 24V controls and accessories use single central power supply for direct control in step of having multiple consoles everywhere. These 24V power supplies comes as dimmable and non dimmable units. In industrial automation devices 24V units are used in inductive applications such as dc motors, indicator lamps, smart devices, solenoids and relays. These home or industrial automation devices use linear or switching power supplies. Some 24v universal power supplies are used in lamp strips, lamps, light box modules, light emitting words, communications, robotics, internet networks, industry control, 3d printer, cctv security systems, lcd monitors and routers.
