TDK Corporation officials announce the introduction of the RWS1000B and RWS1500B “ME” medical AC-DC power supplies designed to provide solid performance at an economical price. In addition to the industrial models, the RWS-B series now includes 1000W and 1500W power levels certified to the medical IEC 60601-1 standard. The 7-year warranty RWS-B series is ideally suited for medical, cosmetic laser treatment and analysis equipment requiring less than 300µA earth leakage current.

The 1000W and 1500W additions are available with 12V, 15V, 24V, 36V, and 48V outputs, adjustable up to -15/+15% of nominal. All models accept an 85VAC to 265VAC input and can operate at full load in -20°C to +50°C ambient temperatures, derating linearly to 60% load from +50°C to +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 bus bars. The terminal block can also be quickly configured for either a vertical or horizontal wiring orientation. The RWS1000B/ME measures 127mm x 63mm x 198mm and the RWS1500B/ME 127mm x 63mm x 261mm.

The TDK-Lambda RWS-B 1000 and 1500W ME models are certified to the safety standards of IEC/ES/CSA/EN 60601-1 and are CE marked according to the Low Voltage and RoHS2 Directives. Input to output isolation is 4,000Vac (2 x MoPP), input to ground 2,000Vac (1 x MoPP) and 1,500Vac output to ground (1 x MoPP) for suitability with B and BF rated equipment. All models offer conducted and radiated performance to EN55011/EN55032, meet EN 61000-3-2 harmonics and EN 60601-1-2 (Edition 4) immunity standards.
