Take charge of your electrical circuits with this switching power supply from RECOM. By converting AC signals between 85 and 264V into a stable 5V DC output, it lets you safely energise components with this voltage rating. An isolation voltage rating of 3kV AC means your equipment stays protected against damage caused by rogue surges. You can use this power supply in steamy settings thanks to its maximum operating humidity of 95% RH.

• Though-hole mounting achieves a sturdy connection to your PCB
• Mean time between failures of more than 1.5 million hours at +25°C, so it's dependable in the long term
• Small dimensions of 33.7 (L) x 22.2 (W) x 19mm (H) to slot into tight spots
• Ideal for harsh conditions thanks to a broad operating temperature range of -25°C to +70°C
• Low weight of 12g so your system stays strain-free

• Renewable energy systems
• Household appliances
• Utility grids

Yes, it has a built-in voltage regulator that limits output ripple and noise to between 100 and 200mV peak to peak. This protects your circuit and improves performance.
