Pin down voltage conversion in compact setups with this switching regulator from RECOM. Thanks to right-angled contacts, it lies flat while connected, helping you settle supply issues without using much space. By reaching up to 91% efficiency, the unit keeps a cool head during conversion so there's no need to hook up a heatsink. An input voltage range between 4.75 and 18V DC makes the regulator a sure fit for standard power supplies. It comes with integrated short-circuit protection, so you can trust it's more than a match for electrical faults.

• Epoxy resin potting and plastic case provide effective insulation to protect against electrical hazards
• Through-hole mounting for quick installation
• Power dissipation of just 0.65W to minimise energy loss
• Maximum line regulation rating of ±0.5%, ensuring a stable output voltage for a reliable power supply

• Remote-control devices
• Electric vehicle chargers
• Construction industry

No, this unit generates low ripple voltages up to 30mV, so there's no need to use shielded cables to protect against electrical noise.
