With its high eciency, frequency, and speed, this power supply is an essential part of your laser
engraver, converting standard AC power into the high-voltage DC power needed for your laser tube.
The lightweight, compact MYJG-40W laser power supply is easy to operate and highly compatible
with a variety of 40W CO
₂
lasers. It connects directly to your system and works without similar
devices’ usual heat-generating heavy ballast resistance. Using this power supply ensures quick
operation and maximizes the performance of your laser device, extending its service life.

Safety Information
• The input voltage for this device is controlled by a switch on the right side. Make sure that the
selected voltage matches your country’s power supply prior to use.
•
ONLY
install, adjust, or remove this device when all power to your engraver is turned o and
unplugged.
• Similarly, make sure that your engraver is properly grounded prior to use. Use only with
engraving machines that employ a three-prong plug with a ground terminal. For best results,
use with an EMI lter.
• Be careful that the positive and negative output terminals are properly connected to the
proper poles of your laser device prior to use.
• Be
EXTREMELY
careful around the high-voltage anode wire and its connections. The
connection to the laser tube should be sealed to prevent sparking.
• Ensure that your CO
₂
laser’s water cooling system is operating properly during use. In
systems equipped with a protective sensor in their water system, this power supply will
automatically cut o power to the laser if a malfunction is detected on the sensor’s circuit. In
systems without such a circuit, however, the water cooling system is no less important and its
proper operation should be manually ensured prior to each use.
• There is a bleeder resistor inside your power supply. It generally discharges harmlessly into
the ground connection, but do not open this device without specialized training.
• Just like your CO
₂
laser, this power supply should be kept in an environmentally-controlled
room to ensure proper operation. Do not use the device outside of its approved temperature
and humidity ranges.
