CUS1500M Series Power Supplies

TDK-Lambda’s CUS1500M series of AC-DC power supplies extends the CUS-M family of products to now cover 30 W to 1500 W.  The CUS1500M has both medical and ITE (information technology equipment) certifications and is ideally suited for industrial, medical, cosmetic laser treatment, and analysis equipment requiring less than 300 µA earth leakage current, low audible noise, and Class B EMI.

The 1500 W additions are available with 12 V, 15 V, 24 V, 36 V, and 48 V outputs, adjustable from -15%/+20% (+15% for the 48 V) of nominal. All models accept an 85 VAC to 265 VAC 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.

The CUS1500M measures 127 mm x 63 mm x 261 mm and has a seven-year warranty. Other features include a 5 V, 1 A standby voltage, remote on/off, parallel operation of up to five units, an isolated open collector DC good/fan fail signal, and a variable speed fan that produces 45 dBA (typical) at +30°C at 70% load.

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 TDK-Lambda CUS1500M models are certified to the safety standards of IEC/ES/CSA/EN 60601-1, IEC/UL/CSA/EN 60950-1 (62368-1 pending), IEC/EN 62477-1 (OVC III), and are CE marked according to the Low Voltage, EMC, and RoHS2 directives. Input to output isolation is 4,000 VAC (2 x MoPP), input to ground 2,000 VAC (1 x MoPP), and 1,500 VAC output to ground (1 x MoPP) for suitability with B and BF rated equipment. All models offer conducted and radiated performance to EN55011/EN55032-B, meet EN 61000-3-2 harmonics, and are compliant to EN 61000-4 and EN 60601-1-2 (Edition 4) immunity standards.
