SAN DIEGO – TDK-Lambda Americas Inc. in San Diego is introducing the 1500-Watt CUS1500M series of AC-DC power supplies for industrial, medical, cosmetic laser treatment and analysis equipment requiring less than 300 microamps earth leakage current, low audible noise, and class B EMI.
The announcement extends the CUS-M family of products, which cover 30 to 1500 Watts. The CUS1500M has medical and Information Technology Equipment (ITE) certifications.
The 1500-Watt additions are available with 12, 15, 24, 36, and 48-volt outputs, adjustable from -15/+20 percent (+15 percent for the 48-volt) of nominal.
All models accept an 85 to 265-volt AC input and can operate at full load in ambient temperatures from -20 to 50 degrees Celsius, derating linearly to 60 percent load from 50 to 60 C.
High operating efficiencies to 88 percent reduce internal waste heat and component temperatures, resulting in electrolytic capacitor service life predictions of at least 10 years.
The CUS1500M measures 127 by 63 by 261 millimeters and has a seven-year warranty. Other features include a 5-volt, 1-amp standby voltage, remote on/off, parallel operation of as many as five units, an isolated open collector DC good / fan fail signal and a variable speed fan that produces 45dBA (typical) at 30 C at 70 percent load.
To facilitate safe and easy installation of these power supplies, output cable connections are made to screw terminal blocks with covers rather than bus bars. The terminal block also can be configured quickly 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 volts AC (2 by MoPP), input to ground 2,000 volts AC (1 by MoPP) and 1,500 volts AC output to ground (1 by 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 comply with EN 61000-4 and EN 60601-1-2 (Edition 4) immunity standards.
