A 400W laser power source for a major OEM manufacturer of medical equipment and features a 60A constant current source and can drive up to 35W CW laser diodes.

UK Power supply specialist, Ferrus Power, has demonstrated its extensive design capability by developing a new 400W laser power source for a major OEM manufacturer of medical equipment. Featuring a 60A constant current source and nominal voltage of 2V DC the product can drive up to 35W CW laser diodes. In addition a TEC output rated at 250W/25V DC is provided with reversible polarity for driving external peltier devices for diode cooling or heating.

Laser and TEC current is controlled via 0-10V DC external programming in each case.

Current monitoring for both laser and TEC is provided in 0-10V DC format with voltage monitoring proportional to output.

For safety purposes a further laser interlock control offers beam attenuation and shuts down the laser output to meet the requirements of 21 CFR 1040.10.

Signal and control connections are via 16W IDC whilst laser and TEC are via high current screw terminal block.

The need for an external power supply to drive ancillary microprocessor control circuitry is removed as the product also features low voltage outputs of +5V DC,+/-15V DC and 24V DC via six-way 0.156in header.

The product is suitable for worldwide applications and offers universal mains input operation of 90 - 264V AC with active power factor correction to meet the line harmonic distortion requirements of EN61000-3-2 class D.

The product is currently undergoing medical approvals testing to EN60601-1.

Ferrus has the capability to design and manufacture similar products to suit the laser and opto-electronics industry and would welcome enquiries.
