TDK Corporation's 1000 W and 1500 W models are the latest addition to the TDK-Lambda RWS-B series of industrial and medical power supplies. All models accept an 85 V_AC to 265 V_AC input and can operate at full load in -20°C 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.

These 1000 W and 1500 W additions are available with 12 V, 15 V, 24 V, 36 V, and 48 V outputs, adjustable from -15/+10% of nominal. 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 mm x 63 mm x 198 mm and the RWS1500B 127 mm x 63 mm x 261 mm.

Options for the power supplies include medical certification, double sided board coating, reverse airflow (which extends operation to +70°C ambient temperatures), remote on/off, current share, and an isolated DC Good/Fan Fail signal.

The TDK-Lambda RWS-B 1000 W and 1500 W models are certified to either the safety standards of UL/CSA/EN 60950-1 or UL/CSA/EN 60601-1 (/ME suffix for medical) and are CE marked according to the low voltage and RoHS 2 directives. The models offer conducted and radiated performance to EN55011/EN55032-B, (-A for /ME suffix) meet EN 61000-3-2 harmonics, IEC 61000-4 immunity, and SEMI F47 line dip standards.
