Frequently Asked Questions - MYJG150W Vevor

What types of control signals does the MYJG150W power supply accept?

The power supply accepts a TTL signal (high or low), a PWM signal (20-50 kHz, 5V duty cycle), and an analog signal 0-5 V to regulate laser power.

How to connect the laser tube to the power supply?

Connect the high voltage (HV+) to the anode of the CO2 laser tube (reflector). The current circuit (negative terminal) connects to the cathode (laser output) via an ammeter.

What is the required input voltage?

The power supply operates on an AC input of 100 to 240 V, 50/60 Hz.

Does the power supply have overcurrent protection?

Yes, it is protected at 130% of the maximum output current.

Can the power supply be used without a laser tube connected?

Yes, briefly: it supports open circuit for a short time thanks to its built-in protection, but it is not recommended to leave the high voltage output open.

How to know if the power supply is working correctly?

The 'LASER' LED lights up when the laser fires. If the LED is on but the laser tube does not light up, the tube is probably defective. The 'P' LED indicates active protection, and 'L' indicates the presence of a TTL signal.

What essential safety precautions are required?

The laser tube must be constantly water-cooled. The high voltage output must never be left open. Use a grounded outlet and ensure strict grounding of the housing.

Is the power supply compatible with all CO2 laser tubes?

It is designed to be compatible with CO2 laser tubes from different manufacturers, thanks to simple control ports and automatic detection.

What is the recommended operating temperature?

The ambient temperature should be between -10 °C and +40 °C for normal use, although the device supports -30 °C to +65 °C.

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. It is small in size, light in weight, easy to operate, and has 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 or 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 meter 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 to integrate. Supports laser tubes from various manufacturers.

Port control is simple, 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, determining the size of the laser power.

The power supply has an open-circuit protection function: the power supply can work on the 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, 12 hours aging test, 7 seconds, 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 light is on and Laser Tube is not firing, then laser tube is broken. If laser tube is firing, then laser power is normal.

(P) Lights when Protection circuit is functioning

(L) Lights when Test Switch is Pressed or TTL Signal is present
