Frequently Asked Questions - MYJG60W Vevor

How to connect the MYJG60W power supply to the CO2 laser tube?

Connect the high voltage output (HV+) to the anode of the laser tube (reflector) and the current circuit to the cathode (laser output). Use an ammeter in series if necessary.

What types of control signals are supported?

The power supply accepts TTL signals (high or low level) and analog 0-5 V or PWM signals. Selection is made via the control connector.

How to use the protection function?

The power supply has a protection switch that can be connected to a water flow detector or enclosure switch. In case of anomaly, the laser output is cut off.

What to do if the laser does not turn on?

Check if the LASER indicator is lit. If yes, the tube may be defective. Otherwise, check connections, input voltage, and control signals.

Can I use the power supply without a laser tube connected?

Yes, but only for a short time and with proper grounding. The power supply supports temporary open circuit, but prolonged use may damage it.

What is the required input voltage?

The power supply operates on mains voltage of 100 to 240 V AC, 50/60 Hz. Ensure the socket has a ground terminal.

How to adjust the laser power?

Power is controlled either by an analog 0-5 V signal (via the wattmeter) or by TTL pulse width modulation (PWM). Connect the appropriate signal to the IN port.

What are the status indicators and their meaning?

The LASER indicator lights up when the laser fires. The P indicator lights up when protection is active. The L indicator lights up when a TTL signal is present and the test switch is in position.

Do I need to ground the device?

Yes, the power supply housing must be strictly grounded to avoid electric shock. Use a three-wire plug with grounding.

What are the important safety precautions?

Never leave the high voltage output open circuit. Ensure water cooling of the laser tube. Discharge internal capacitors after power-off (wait a few seconds). Avoid excessive humidity.

This is the original instruction. Please read all manual instructions carefully before operating. VEVOR reserves a clear interpretation of the user manual. The appearance of the product shall be subject to the product you received. Please forgive us that we won't inform you if there are any technology or software updates on our product.

Key features:

The product is a successful high-efficiency, high-frequency, high-speed CO2 laser supported power supply, small size, light weight, easy to operate with good matching performance for lasers. It can be directly connected with the laser, saving the bulky and severe heating of resistance. The power supply can make the CO2 laser lighting easy, taking advantage of the full performance of CO2 laser, improving conversion efficiency, and extending the life of the laser.

Key Technical Parameters:

1. Input voltage: AC 100-240V
2. Response speed: ≤ 1mS.
3. TTL level switch control: effective level can be high and low select
4. Protection switch: can be used for the detection of water, protection lasers, or protection when opening the housing, etc.
5. Laser power regulation: (1) The output current of the laser power is regulated by the power meter. (2) controlled by PWM (TTL level).
6. Feedback Interface: The power supply itself can have a feedback interface and can be used for closed-loop control to verify the actual working current of the laser.
7. Environment of use: Temperature (-10 to 40 degrees C), humidity: 85%.

Instructions For Use:

1. Connection of the Laser Tube: The high-voltage (HV-plus) of the power supply must be connected to the anode (full reflector) of the laser tube. The current circuit of the laser power supply is connected to the cathode (laser output) of the CO2 laser tube via a current me directly)
2. Connection of the Control Signal: In Figure 1 (or Figure 2), the signal line is reliably connected to the control end of the laser power supply.
3. Control Signal Input: As shown in Figure 3, the DAC signal or T signal output from the external computer are connected to the laser power supply as required, and to control laser tube output power.
4. Voltage Selection: The laser power supply requires inputs of AC 100-240V, 50/60Hz.
5. Additional Features: The laser power supply has a set of protective switches for protection for water flow, when the housing is opened.

Important Notes:

1. The laser tube must be cooled with water when working!
2. High-voltage output must not be open! (The high-voltage output positive and negative ends must be properly connected to the laser positive and negative ends).
3. The internal power supply has been designed to discharge any residual charge at shutdown, but can generally take up to two seconds. But for safety reasons you should still be careful of electric shocks! Insulation safety requirements of the suspended 40KV high voltage must be guaranteed at both ends of the high-voltage output).
4. The laser power supply must use a three-hole socket with a ground end. The case must be strictly grounded to avoid electric shock.

Laser Power Supply Main Features:

New stable laser power supply, the biggest features: the use of mod design automatic detection of laser power signal, automatic detection of water protection!

The mounting holes are all consistent and suitable for plant line installation. The use of zero-current half-bridge soft switch circuit makes the power supply highly efficient, with fast response speed, and easy integration. Supports laser tubes from various manufacturers.

Port control is simple, and can use either high or low level signals. TTL can control the laser start and stop.

At the same time, there is an abnormal protection switch to detect whether the outside water, ventilation, etc. are functioning.

Laser power regulation can be controlled between 0 and 5V analog signals or PWM signals, which determine the size of the laser power.

The power supply has an open-circuit protection function: the power supply can work on an open

circuit for a short time when the protection is well grounded, which avoids damage to the laser power supply due to the bursting of the tube.

Factory aging test: Each power supply is tested under full load at a temperature of 60 degrees, with a 12-hour aging test, and is powered on and off 500 times.

Terminal definitions, LEDs, and power detection instructions:

Power supply status lights:

(LASER) Lights when laser is firing: If the light is on and the laser tube is not firing, then the laser tube is broken. If the laser tube is firing, then the laser power is normal.

(P) Lights when the protection circuit is functioning. (L) Lights when the test switch is pressed or a TTL signal is present.
