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 —one per cent, load regulation of —one per cent for outputs 1 and 2 (—seven per cent for output 3, and —five per cent for output 4), and ripple and noise of the greater of 50mV or one per cent. Transient response (V1 and V2 outputs) is the greater of 150mV, or three per cent for a 25 per cent load change at 1A/µs.

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 Rs.4,324.40 ($95) each for 1,000-piece quantities.
