Introduction <br> Model:CO2-TUBE-40W-70CM <br> Output Power:40W <br> Wavelength:10600nm <br> Working Voltage:15KV (Trigging Voltage=22KV) <br> Working Current:15mA <br> Divergence:1.95(beam diameter) <br> Dimensions:Length 700mm <br> Input voltage: AC 220V+30 or AC 110V+20 (to be specified when placing order). <br> Maximum output voltage:DC25KV (40W;50W) / DC28KV (60W) / DC35KV (80W) <br> Maximum output current: DC20mA (40W;50W)/ DC23mA (60W) / DC28mA (80W) <br> Isolation Withstand voltage: Input-output, input-enclosure: AC2000V-10mA-60s; negative pole of output connected to enclosure. <br> Protection: with well-grounded enclosure, output circuit of power supply can be open for short time (but arc between positive pole and enclosure should be avoided). <br> Response time (from time of input being available to the output current being up to nominal value)<1ms <br> TTL voltage level control: effective voltage level can be high or low through setting. <br> Protection switch: for detection of cooling water, to protect laser device; or activate with enclosure is opened. <br> Laser power adjustment: (1) by adjusting the output current of power supply through resistor; (2) through PWM control (magnitude being TTL voltage level). <br> Environmental requirements: temperature (-10 to 40centidegree), relative humidity<85%.
