TDK announced the introduction of the RWS1000B and RWS1500B Industrial AC/DC power supplies, designed to provide solid performance at an economical price, and are offered with a 7-year warranty. Expanding the series to seven power levels from 50 W to 1500 W, the RWS-B series is ideally suited for industrial, test & measurement, broadcast, communications, and LED signage applications.
The supplies are available with 12 V, 15 V, 24 V, 36 V, and 48 V outputs, adjustable from -15/+10% of nominal. All models accept an 85 Vac to 265 Vac input and can operate at full load in -20 to +50°C ambient temperatures, derating linearly to 60% load at +60°C. High operating efficiencies of up to 88% reduce internal waste heat and component temperatures, resulting in electrolytic capacitor service life predictions of at least ten years.
To facilitate safe and easy installation, output cable connections are made to screw terminal blocks with covers rather than busbars. The terminal block can also be quickly configured for either a vertical or horizontal wiring orientation. The RWS1000B measures 127 x 63 x 198 mm and the RWS1500B 127 x 63 x 261 mm.
Options for the power supplies include double sided board coating, reverse airflow (which extends operation to +70oC ambient temperatures), remote on/off, current share and an isolated DC Good/Fan Fail signal.
The TDK-Lambda RWS-B 1000 and 1500 W models are certified to the safety standards of UL/CSA/EN 60950-1 and are CE marked according to the Low Voltage and RoHS2 Directives. All models offer curve B conducted and radiated performance to EN55011/EN55032-B, meet EN 61000-3-2 harmonics, IEC 61000-4 immunity and SEMI F47 line dip standards.
