AAD160 AC/DC from Tamura

Tamura's AAD160 series of compact, regulated triple- and quad-output switching power supplies delivers 160W for 1U-high applications.

These universal AC-input supplies with power factor correction, in nine models, provide 1.8-48V in triple output versions (1.8-15V at main output 1), and provide a low-current output at -1.8-48V in quad versions. Each output offers a wide range of factory set-points. Each supply has two independently regulated main outputs (up to 16A and 14A, respectively, for main outputs 1 and 2), substantially improving cross regulation performance. Features include a line regulation of 1 percent, load regulation of 1 percent for outputs 1 and 2 (7 percent for output 3, and 5 percent for output 4), and ripple and noise of the greater of 50mV or 1 percent. Transient response (V1 and V2 outputs) is the greater of 150mV, or 3 percent for a 25 percent load change at 1A/?s.

The supplies provide remote sense and power fail functions, and overcurrent and overvoltage protection. Current-share and inverted status/control signals are standard options. All models are RoHS compliant, qualified to UL60950-1/CSA 22.2 60950-1-03/BAUART EN60950-1 safety standards, offer CB Reports (IEC60950-1) and bear the CE Mark (LVD). Emission levels meet EN55022 (Level B)/FCC Part 15 Class B standards.

Standard units are available from stock. The supply is priced at $95 each for 1,000-piece quantities.
