    TDK-Lambda Unveils 150- and 240-W Power Supplies

    Sept. 5, 2012
    Evaluation Engineering

    September 5, 2012. TDK Corporation has announced the new TDK-Lambda ZWS-BP series of compact, open-frame, 150-W and 240-W power supplies. These single-output supplies have a low profile of 1.46” to 1.65” and compact footprints of 2.95” x 6.3” or 3.31” x 7.09”.  Moreover, these units can provide a peak output power of up to 200% (for motors, pumps, etc.), making them suitable for applications in industrial, gaming, point-of-sale, test-and-measurement, LED signage, and communications equipment. 

    These new TDK-Lambda AC/DC supplies feature a universal 85- to 264-VAC, 47- to 63-Hz input. The ZWS-BP is designed to withstand 3 kVAC, input-to-output. In addition, they can operate with a DC input over the range of 120 to 370 VDC. The supplies are available with an output voltage of 24, 36, or 48 VDC and include an onboard output adjustment potentiometer.

    With convection cooling (no fans required), these supplies provide up to 150 or 240 W of output power.  The operating temperature range is from -10°C to +70°C with derating above +50°C. The output is floating so it can be used as either a positive or a negative polarity. The power-saving efficiency is up to 91%. Standard features include overvoltage and overcurrent protections. Optional remote on/off connections are available to allow for remote control of the supply.

    The company reports that the ZWS-BP series is an extension of the ZWS series, which were employed in the high-definition Diamond Vision video displays that were built by Mitsubishi Electric and have been used to power some of the world’s largest LED displays located at the Cowboys Stadium (Texas), Yankee Stadium (New York) and many other global sites.

    The ZWS-BP series feature global ITE and general-purpose safety agency certifications per UL/CSA/EN60950-1 and EN50178 (OV II). They are CE marked and meet the conducted and radiated EMI requirements of EN55011/EN55022-B, VCCI-B, and FCC Class B. These units are RoHS compliant and include a 5-year warranty.

    They are priced from $100.00 each in quantities of 100 units.
