Traco Power Switching Regulator, 470μF Maximum Capacitive Load, 95% Efficiency - TSRN 1 Series - TSRN 1-24120SM

Get your power supply and electronic equipment in line with this switching regulator from Traco Power. It takes variable inputs from 13.5 to 42V DC and gives you ±12V DC in return. This output voltage is adjustable between 4.5 and 13.5V DC to provide the precise level your devices need. Thanks to the unit's remote on/off feature, you have the convenience of hands-off control. Secure installation is no trouble, as it's compatible with surface mounting. Thanks to this regulator's short-circuit protection, it shrugs off common faults and automatically restarts after an issue to cut downtime.

Features & Benefits

• Output load accuracy of ±2% for reliability
• Converts up to 95% of input power, minimising energy waste
• Low ripple voltage of 75mV to cut disruption from electrical noise
• Plastic and epoxy insulation to keep you safe from shocks
• Operates reliably in a temperature range from -40°C to +85°C

Applications

• Automotive engineering
• Games consoles
• Domestic appliances

Do I need to install external components to cool this regulator?

No, the product's 95% efficiency limits heat build-up from lost power. This keeps its internal temperature down and removes the need for a heatsink.
