Glass laser tube 50W CO2 800mm length, 50mm Dia laser engraving cutting machine a

  

Here is the laser engraver with this laser tube for your reference: 2. Maximum output voltage:DC25KV (40W;50W) / DC28KV (60W) / DC35KV (80W) Maximum output current: DC20mA (40W;50W)/ DC23mA (60W) / DC28mA (80W) Isolation Withstand voltage: Input-output, input-enclosure: AC2000V- 10mA-60s; negative pole of output connected to enclosure. 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). Response time (from time of input being available to the output current being up to nominal value).
