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

ELECTRONICS: 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 to 150W supplies that accept a wide ac input range, have a low profile of only 1.3 inches and a compact footprint of 3 x 5 inches, 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 90-264V ac, 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 264V ac, 63Hz, which is important for many non-patient contact medical and dental applications. In addition, the CSS150 is designed to withstand 4kVac, input-to-output. The series are available with an output voltage of 12V, 15V, 36V, or 48V dc, all of which have a +/-3 percent adjustment range.

With convection cooling (no fans required) these supplies provide up to 100W of output power.  For higher power applications, with forced air cooling of 2.5 m/s, the output power increases to 150W. The operating temperature range is from 0 to +70C 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 0.5W, which complies with many energy-saving initiatives, plus the operating power-saving efficiency is typically 89 percent. Other standard features include overvoltage and overcurrent protections. The input and output connections mate with standard Molex connectors.  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.
