Single-output AC-DC power supplies have low profile

TDK-Lambdavisit website


Lambda UK is launching the new ZPSA range of single-output 20, 40 and 60W AC-DC power supplies, all of which boast a very low profile. For example, the ZPSA20 measures just 88.9 x 50.8 x 20.32mm, so these supplies are suitable for applications such as video/audio routers, datacoms, point-of-sale equipment, low-power LED signs and lighting.

While the ZPSA20 series is available in standard output voltage configurations from 3.3-24VDC, the ZPSA40 and ZPSA60 are available from 3.3-48VDC. Intermediate voltages for each series are available on request. The 40 and 60W models are industry-standard 2 x 4inch format, and the 20W model measures 2 x 3.5inch.

AC input range for the ZPSA20 is 85-264V AC, 47-63Hz, or 120-225V DC. For the ZPSA40 and ZPSA60 series, the universal input is 90-264V AC, 47-63Hz. Designed to complement Lambda's popular KPSA PCB-mountable AC-DC power supply range, the ZPSA series is similarly rated for convection-cooled operation between 0-70degC, with appropriate derating. Over-voltage protection and short-circuit protection are standard for all three series.

To maximise design-in flexibility, Lambda is making the units available in either an open-board configuration with Molex connectors, or in a pinned version for PCB mounting to special order.

The ZPSA series meet EN 61000-4 immunity and Class B EMI standards, and all models are CE-marked and safety approved to UL60950-1, CSA60950-1, and EN 60950-1.
