TRACO POWER TSR3-0533

TRACO POWER DC/DC Converters TSR3 SERIES 3 Watt Non-Isolated / POL DC-DC Converter TSR-3 Series, 3 A Measures: 0.61 x 0.41 x 0.24” Features ◆ High performance 3 Amp. switching regulator ◆ Suitable for positive & negative output circuit ◆ High efficiency up to 95 % ◆ Adjustable output voltages ◆ Wide input voltage ranges 2.5–5.5, 4.5–14 and 10–30 VDC ◆ Over-temperature protection ◆ Short circuit protection ◆ Remote On/Off input ◆ Low output ripple & noise The TSR 3 models are non isolated step down switching regulators. Since production ◆ 3-year product warranty May 2013 they can also be operated with negative output voltage. They come in a very compact open frame package of 15.5 x 9.4 x 6.2mm. The high efficiency of up to 95% admits a full load operation up to 50°C and up to 85°C with 50% current reduction. A low standby current, a very wider input range and no requirement for heatsink give these switching regulators a significant advantage over linear regulators. Togther with a remote On/Off input and protection against short circuit and over temperature the TSR 3 Series models are ideal point of load regulators for high reli- able and energy critical applications.
