Ferrus Power has developed a new 400W laser power source for a major OEM manufacturer of medical equipment. Featuring a 60A constant current source and nominal voltage of 2Vdc, the product can drive up to 35W CW laser diodes. In addition a TEC output rated at 250W/25Vdc is provided with reversible polarity for driving external peltier devices for diode cooling or heating.
Laser and TEC current is controlled via 0-10Vdc external programming in each case. Current monitoring for both laser and TEC is provided in 0-10Vdc 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 +5Vdc,+/-15Vdc and 24Vdc via 6 Way 0.156” header.
The product is suitable for worldwide applications and offers universal mains input operation of 90 – 264Vac 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.
