Traco Power Switching Regulator, SIP3 Package, 12W Power Rating - TSR 1 Series - TSR 1-24120


Bring your power supply in line with your hardware using this switching regulator from Traco Power. It switches input voltages down to a steady 12V DC supply, ironing out the differences between an electrical source and its machine. As it switches up to 95% of its input load, the product makes for a handy energy-efficient power conversion system. A response time of 250μs means the unit tackles sudden input changes in a jiffy. Don't worry about losing power to electrical faults, as the device's integrated short-circuit protection lets it automatically reboot after an issue to skip past excess downtime.

Features & Benefits


• Wide input voltage range between 15 and 36V DC, so it works with many power supplies
• Simple through-hole mounting for a quick and secure connection to a PCB
• Operates in temperatures between -40°C and +85°C, standing up to harsh industrial settings
• Low ripple voltage of 75mV to minimise disruption from electrical noise

Applications


• Warehouses
• Construction industry
• Renewable energy installations
