Complementing its single-output models announced earlier this year, XPiQ has introduced multi-output versions of the ECM40 and ECM60 families of 40W and 60W ac/dc switching power supplies. Approved for Class I and Class II applications, these families provide up to three outputs at voltages ranging from 3.3Vdc to 48Vdc.

Features include a user-adjustable output on the main source (10 percent), line regulation of 0.5 percent, cross regulation of 2 percent, and load regulation of 3 percent on output 1 and 5 percent on outputs 2 and 3. Ripple and noise are within 1 percent peak-to-peak at 20MHz bandwidth, maximum leakage current is 100?A at 115Vac, or 200?A at 230Vac. The supplies come with over-voltage, overload and short-circuit protection. Operating efficiency is 80 to 85 percent, depending on model.

The supplies meet international safety agency approvals for both medical (UL2601-1/EN60601-1) and commercial (UL60950/EN60950) standards. To aid customers' compliance of their end equipment with IEC60601-1, the ECM40 and ECM60 have dual-fused universal AC inputs. The supplies, measuring a compact 2-by-4-by-1.2 inches, deliver full power over 0C to 50C and will operate at up to 80C, suitably de-rated (only 5 CFM of cooling). The 40W series is priced at $34.70, and the 60W models are $39.30, both in 1,000-unit quantities.
