Shielded DC power converters offer cost-effective reliability for quality-critical designs

RS Components now offers the THL 15WI series of shielded 15W DC-DC converters from TRACO Power. Created to be reliable but cost-efficient, the devices are certified to the latest IEC/EN/UL 62368-1 IT safety standards making them ideal for applications such as instrumentation, mobile equipment, and distributed power architectures for communications and industrial electronics.

The series of power converters are encapsulated in 1" x 1" x 0.4" metal packages with an internal EN 55032 class A EMI filter. They give a versatile 4:1 input range at nominal input voltages of 24V (9V to 36V) or 48V (18V to 75V) DC. Output options, all accurately regulated to within ±1% accuracy, are 3.3V (3400mA max.), 5V (3000mA max), 12V (1250mA max), 15V (1000mA max) or 24V (625mA max) DC single output, and ±12V (±625mA max) or ±15V (±500mA max) DC dual output. Single-output models have a ±10% output voltage adjustment range. All devices offer 1500VDC I/O isolation.

Providing high efficiency up to 91%, the converters can work at full load over an operating temperature range from –40C to +70C, with an MTBF surpassing 1.3 million hours. Overload, overvoltage and short circuit protection are included, as are remote on/off and trim functions. Optional heat sinks are offered to enhance temperature performance.
