TRACO POWER TSR 2-24120N

The TSR 2N series is a 2-amp step-down switching regulator designed as a drop-in replacement for any linear regulator in a TO-220 package. Housed in a compact SIP-3 plastic package, this next-generation point-of-load converter delivers significantly improved key electrical specifications while maintaining a cost-effective design. It accepts an input voltage range of 4.6 to 36 VDC and offers selectable output voltages from 1.2 to 15 VDC. Depending on the specific model, its high-efficiency design allows full-load operation at ambient temperatures up to +95°C (at rated input voltage) without any heatsink or forced cooling. The TSR 2N series also provides important features such as short-circuit protection, current limiting, and undervoltage lockout. Overall, it offers broad applicability across a wide range of environments — particularly well-suited for high-volume projects — delivering a cost-effective solution with high reliability that helps reduce production costs.
