Traco Power Switching Regulator, 91% Efficiency, 1 Output - TSR 2 Series - TSR 2-2433

Place the trust of your power management into the hands of this switching regulator from Traco Power. Its tight load regulation levels off your power supply at a stable 3.3V DC, so there's minimal chance of equipment receiving too much or too little energy. This helps to keep your device running reliably and efficiently. Compact dimensions of 14 (L) x 7.5 (W) x 10.1mm (D) mean you can make maximum use of PCB real estate. An efficiency of 91% lets you operate this regulator at full load in ambient conditions of up to +67°C without needing any forced cooling.

Features & Benefits

• Non-conductive plastic casing offers protection from electric shock
• MTBF of over 13 million hours for reliability throughout its extended service life
• Built-in filter capacitor, which protects against ripple and noise interference
• Resists shock and vibration, so suitable to use in demanding environments

Applications

• Battery-operated equipment
• Industrial electronics
• Data acquisition centres
• Hospitals

Does this regulator protect against power surges?

Yes, the unit includes short-circuit and overvoltage protections, helping to prevent power faults from causing damage to equipment.
