digilog.pk stocks a full range of DC power supplies, lab bench supplies, wall adapters, voltage regulators, switching supplies, and buck-boost converters for electronics projects, lab use, and industrial applications in Pakistan. From a 5V/2A USB adapter for a Raspberry Pi to a 30V/10A programmable bench supply for advanced prototyping, we have reliable power solutions at the best prices.

Why the Right Power Supply Matters

• Stable voltage — prevents microcontroller resets and sensor noise caused by voltage sag
• Adequate current — undersized adapters overheat and damage both supply and load
• Regulation quality — switching supplies offer high efficiency; linear supplies offer low ripple for audio and RF
• Protection features — OVP, OCP, and short-circuit protection save expensive boards
• Pakistan voltage compatibility — all supplies listed support 220V AC 50Hz input

Types Available

• Wall adapters — 5V, 9V, 12V, 24V; switching type; for general electronics
• Lab bench power supply — adjustable 0–30V, 0–10A with digital display
• DIN-rail SMPS — 5V/12V/24V industrial switching supplies for panel installations
• Buck converters — LM2596, XL4016; step-down from any voltage to required output
• Boost converters — MT3608; step-up for battery-powered 12V rails
• Buck-boost (SEPIC) — constant output regardless of input variation
• PoE splitters/injectors — power-over-Ethernet for network cameras and access points

How to Choose

1. Output voltage — match to your circuit; always check min/max input requirements
2. Current rating — sum all load currents; choose supply rated at least 20% above that
3. Regulation type — switching for efficiency; linear for low-noise analog/audio
4. Protection needed — always choose OVP + OCP for microcontroller-based projects
