Stabel power and continuous adjustment

A high speed switch with frequency conversion technology is used to switch the currents of the lamp in a very short time. This allows the lamp to keep stable emission of light, and such stable output makes the continuous UV dimming system output higher light intensity than traditional transformer+capacitor systems. Higher intensity leads to faster curing, less heat from lamp poles, and thus longer lamp life.

The pulse width signals(PWM signals) output with variable frequency technology can be adjusted continuously within the range from 0% to 100%, which can realize stepless adjustment of the power of the UV lamps and thus continuous dimming.

2. Unique multi-stage speed power setting

Through the combination of the ON/OFF state of two external switches, it is possible create four levels of power values to be output. This feature can directly and completely replace existing drive mode of transformer + capacitor, suitable for sites of renovation.

3. Various communication interfaces

Support for Modbus, Canopen, Ethernet and other communication protocols allows networking between multiple power supplies, and between power supplies and other industrial control equipment to meet application requirements of high-end system integration.

4. Flexible use of expansions

All kinds of expansion cards with diverse functions can be used to meet requirements of complex applications specific to different industries, without changing the principal part of the product. This eliminates the time and costs for development of application-specific devices, which cannot be flexibly used for other applications, and allows the devices to be completely integrated with customer systems and for integrated development.

5. Complete protection

Nearly 20 kinds of protection are available to ensure comprehensive protection for equipment while the normal operation of the equipment is not interfered with.

Receiving of (PT100, NTC) temperature detection analog signals, real-time monitoring of lamp temperature, and protection of lamp against over-temperature;

Receiving of fault switch signals from external equipment: when the external equipment fails, the UV variable frequency power supply immediately sends alarms and stops.

6. Quick dynamic response for dimming

Incremental PID control algorithms make the power adjustment very fast. It takes only 500 milliseconds to switch from standby power to maximum power output;

7. Smooth start-up and reduction of impact

The lamp is turned on by means of sampling tunnel excitation mode, which makes the lighting up process more smooth to ensure that the power of the UV lamp keeps rising steadily after the excitation with stable output energy not affected by changes in temperature;

8. Unique standby mode to reduce energy consumption and prolong life 

The unique standby mode is used in combination with the built-in shutter of the UV system. When the shutter is closed, the UV power supply enters the standby mode, in which case the heat released from the lamp enters the reflecting cover, to minimize temperature rise. In order to maintain the stability of the lamp temperature and prevent overheating, the irradiation intensity can be reduced to 10% to reduce energy consumption and prolong the service life.

After entry into the standby mode, because the lamp temperature remains constant, the UV system can quickly restore the preset irradiation intensity required for rapid curing.

 9. Independent air ducts and negative pressure exhaust for heat dissipation

The heat from the radiator is taken away with the exhaust fan, so that the temperature rise of the UV frequency conversion power supply is not more than 40°C. This design effectively improves the temperature rise of the UV frequency conversion power supply as well as the working efficiency and service life of the UV frequency conversion power supply;

10. Variable frequency fan control

The space voltage vector control algorithm is used for conversion to analog output, which controls the output frequency of variable-frequency drive and thus the quantity of air to keep constant pressure and temperature for the lamp and realize fast curing.

In the standby state, a unique control algorithm is used to keep the lamp tube pressure fluctuation within a certain range, so that the lamp takes only 200mS to respond from the standby state to full power output to meet the requirement for fast response curing.
