TDK-Lambda Unveils Compact 100W to 150W Medical & ITE Safety Certified Power Supplies

San Diego, CA - TDK-Lambda has unveiled its latest addition to its line of AC-DC medical and ITE (Information Technology Equipment) power supplies. The new single-output CSS150 series are 100 to150-watt supplies that accept a wide AC input range, have a low profile of only 1.3" and a compact footprint of 3" x 5", making them an ideal choice for applications in non-patient contact medical/dental, light industrial, business, gaming, point-of-sale and instrumentation equipment, to name a few.

These new open-frame supplies feature a universal 90-264Vac, 47-440Hz input, enabling them to be used anywhere in the world. Plus, they can operate from a 120-180Vdc input. These supplies feature a low leakage current of less than 250µA at 264Vac, 63Hz, which is important for many non-patient contact medical and dental applications. In addition, the CSS150 is designed to with-stand 4kVac, input-to-output. The series are available with an output voltage of 12V, 15V, 36V, or 48Vdc, all of which have a +/-3% adjustment range.

With convection cooling (no fans required) these supplies provide up to 100-watts of output power. For higher power applications, with forced air cooling of 2.5 m/s, the output power increases to 150-watts. The operating temperature range is from 0°C to +70°C and the output is floating so it can be used as either a positive or negative polarity.

Remote On/Off connections are provided to allow for remote control of the supply. The off-load power draw is less than 0.5-watt, which complies with many energy-saving initiatives, plus the operating power-saving efficiency is typically 89%. Other standard features include overvoltage and overcurrent protections. The input and output connections mate with standard Molex connec-tors. And, fuses are provided internally on both the AC Line and Neutral inputs (dual fuses).

The CSS150 series have global medical safety agency approvals per UL/EN/IEC60601-1 as well as ITE and general purpose safety agency approvals per UL/EN60950-1, are CE Marked, meet the conducted and radiated EMI requirements of EN55022-B and FCC Class B (which is much tougher to meet than Class A), and they are RoHS compliant.

These units are available now and economically priced at $40.00 each in 1000 piece quantities.
