Power supply INTER-TECH SDS 12-90 12V 90W switching unit for 12V devices

INTER-TECH SDS 12-90 is a switching power supply that provides a regulated 12 V DC output with a maximum power of 90 W. The unit is intended to power a variety of low-voltage devices such as LED strips, routers, CCTV cameras and other 12 V equipment. Its compact housing and standard DC output simplify integration into residential and commercial installations where stable 12 V supply and reliable performance are required.

Advantages

The switching topology delivers efficient conversion from mains to 12 V, reducing heat generation and improving energy use compared with linear supplies. The design offers stable voltage under varying load conditions and protection features typical for switching units, enabling continuous or intermittent operation of connected devices. Compact dimensions and a durable enclosure support straightforward mounting and space-saving installation.

Suitable for

• Powering 12 V LED strips and lighting modules
• Supplying network equipment such as routers and switches that accept 12 V input
• Providing power for CCTV cameras and other surveillance devices
• Use in hobby electronics, small embedded systems and instrumentation requiring 12 V

Key specifications

• Output voltage: 12 V DC
• Maximum output power: 90 W
• Output current capability suitable for devices drawing up to the rated wattage
• Switching (SMPS) topology for mains-to-DC conversion
• Compact metal/plastic enclosure for indoor installation
• Typical operating modes: continuous or intermittent operation, depending on cooling and load

How to use

Install the power supply on a stable surface or mounting point with adequate ventilation. Connect the mains input to the supply using appropriate wiring and protective devices in accordance with local electrical codes. Verify the device to be powered accepts 12 V DC and that its current draw does not exceed the supply’s rated capacity. Connect the 12 V output to the load, observing correct polarity. Power on the mains supply and check the output voltage and device operation before finalizing the installation.

Recommendations

Place the unit in a dry, well-ventilated location and avoid covering the enclosure to maintain cooling. Use appropriately rated cables and connectors to minimise voltage drop at higher currents. For installations with continuous high loads, ensure sufficient ventilation or consider derating to maintain longevity. Follow local safety regulations and, if unsure, consult a qualified electrician for wiring and mounting.
