Small switcher powers medical applications

Edited by the Electronicstalk editorial team Mar 6, 2008

High-density low-leakage 200W medical power supply features a wide range 85-264V AC input with active power factor correction to minimise input harmonic distortion.

The SMM201 medical grade switcher is the first member of the new ZVS Eagle II family of high-efficiency medical power supplies from Conversion Devices.

The high-density low-leakage 200W medical power supply features a wide range 85-264V AC input with active power factor correction to minimise input harmonic distortion.

The SMM201 measures a mere 35.3 x 76.2 x 127mm with a power density of 13.33W/in3.

The unit delivers its full rated output of 200W with 76mm/s of forced air and has a convection rating of 150W.

As a single-output model the SMM201 features a high current main output with available voltages from 12 to 60V DC up to 200W.

The dual-output model has a second output with voltages ranging from 3.3 to 12V with a current rating up to 5A.

Features include a built-in CISPR 22 Class B EMI filter.

Safety earth leakage current is less than 140uA at 132V AC input and 280uA from a 220V AC input.

The new SMM201 model has an operating temperature range of 0 to 50C without derating and can function up to 70C by derating the output 2.5%/C.

This small low-power switcher is ideally suited for a wide variety of medical applications including: medical diagnostic devices, patient monitors, cosmetic lasers, and respiratory systems.

The SMM201 meets worldwide medical safety and performance standards of UL60601, CSA 22.2 No 601.1.

IEC601-1 and EN60601-1.

Availability is from stock to 6 weeks depending on output voltage configuration.

Pricing begins at US $190.00 in 10-piece quantities.
