        激光电源使用说明:
        (1)激光管的连接:
        激光电源的高压(HV+)必须与二氧化碳激光管的阳极(全反射端)相连。激光电源的电流回路,通过一个电流表(或直接)与二氧化碳激光管的阴极(激光输出端)相连。
        (2)控制信号的连接:
        如图1(或图2),将控制信号线分别可靠接入激光电源的控制端。
        (3)控制信号的输入:
        如图3所示,将外部计算机输出的DAC信号及TTL信号按要求输入激光电源,即可控制激光管按要求输出激光。
        (4)电压选择:
        激光电源要求输入为220VAC/50Hz,如需110VAC应特别订购。
        (5)附加功能:
        激光电源有一组保护开关,可串联水保护,打开外壳时的保护等。
        注意事项:
        1.激光管工作时必须用水冷却!
        2.高压输出端不得开路!(高压输出正负端与激光器正负端必须正确连接。)
        3.电源内部已加入泄放电阻,电源停电后一般可在两秒内将残压放完。但为安全起见,仍然应注意,当心电击!(高压输出两端必须保证悬地40KV高压的绝缘安全要求。)
        4. 激光电源必须使用带接地端的三孔插座。机壳必须严格接地!以免触电。

        Instructions of Laser Power Supply
        (1) Connection of laser tube
        The high voltage (HV+) of the laser power supply shall be connected to the anode (full reflection terminal) of CO2 laser tube. The current circuit of the laser power supply is connected to the cathode (laser output terminal) of CO2 laser tube through an ammeter (or directly).
        (2) Connection of control signal
        Referring to Figure 1 (or Figure 2), control signal shall be reliably connected to control terminal of the power supply.
        (3) Input of control signal
        Referring to Figure 1 3, after connecting the DAC output signal and TTL signal of external computer with the power supply, the laser tube shall work as expected.
        (4) Voltage
        Generally, power input of the power supply shall be 220VAC/50Hz. If 110VAC is needed, please specify when placing order.
        (5) Auxiliary function
        A group of protection switches are reserved for detection of cooling water, open enclosure protection and so on.

        Cautions: 
        1. The laser tubes shall be cooled by water during working.
        2. HV output terminal shall not adopt open circuit! (HV output terminals shall be properly connected to the anode and cathode of the laser tube)
        3. Discharge resistance has been equipped inside the power supply and the residual voltage will be fully discharged 2s later after power off. Attentions should be given to avoid any electric shock! (Both output terminals of the high voltage shall ensure the isolation safety of the overhead 40KV.)
        4. Three-pole socket with earthing contacts shall be used to laser power supply. The enclosure should be well grounded to avoid electric shock.
