警告和注意标签是用于对手册中基本和危险的信号提醒注意。标签将显示与它们有关的信息。
表示可能会引起伤害和设备故障或者长期工作会危害健康的环境。
IP400VPCB是专为IONPURE制造的持续电离模块而特别设计的。这些模块在本手册中称为“LX模
块”。
该电源是通过可控硅桥的相位角控制来实现把单项交流电转变成脉动的直流电。最大直流输出为
400v直流,交流输入440V,交流的输入必须通过变压器进行隔离。
最大电流输出可选择2.5,4,6.5和10。“电流反馈回路”控制电流使其不受外部负载的影响。
电源能以衡压或衡流模式进行控制。在衡压模式下,输出电压将维持在操作者设定的数值上,除非
电流超过极限值。如果负载阻值减少很多造成电流超过极限值,那么电压将自动降低,使其回到极
限值内。
在衡流模式下,输出电流不受负载电阻变化的影响将自动保持在设定数值上,除非电压需要超过交
流电源电压的90%。电压限定在最大数值,如果外部负载继续增大,输出电流将会减小。
CAUTION AND WARNING MESSAGES
5ARNING and CAUTION labels are used to attract attention to essential or critical information in this manual. The
labels will appear next to the messages associated with them.
Warnings indicate condition, practices, or procedures that must be observed to avoid
personal injury or fatalities.
Cautions indicate a situation that may cause damage or destruction of equipment or may
pose a long-term health hazard.
GENERAL DESCRIPTION
T6 6666 DC power controller IP400VPCB was designed specifically to provide DC power to continu
electrodeionization modules manufactured by Ionpure Technologies. These modules will be referred to as “LX
modules” in this manual.
his 4er controller util44s a phase-angle fired SCR bridge to produce a variable DC output from a single-phase
AC input. Maximum DC output voltage is 200, 300 or 400 VDC, corresponding to an AC input voltage of 220, 330,
or 440 VAC, respectively. The AC input must be isolated from the AC mains by an isolation transformer.
The maximum DC output current can be jumper selected at 2.5, 4, 6.5 or 10 amperes. A “current fold back”
control circuit limits the maximum current to these values regardless of load resistance.
The controller can be operated in either constant voltage or constant current mode. In constant voltage mode, the
DC output voltage will be maintained constant at the value selected by the operator, except in cases where the
current limit is reached. If the load resistance decreases sufficiently so that the current reaches the current limit,
the voltage will be reduced automatically to maintain the current at the limit.
In the constant current mode, the output current will be maintained constant at the selected value, regardless of
the load resistance, except in cases where the voltage required reaches the maximum DC voltage possible (90% of
the RMS AC input voltage). The voltage would then be limited to the maximum value, and if the resistance
continues to increase, the output current will decrease.

电源的输出能用继电器控制其通断。如水流开关。对应0-5v输出的电压和电流可以用外部的电压和
电流表显示。
电源包含一块线路板和安装铝板。
The DC output voltage or current can be adjusted by the following methods:
• An optional display board, Part No. IP DISP1, which can control and display the DC output from one power
controller.
• An optional display board, Part No. IP DISP8, which can control and display the DC outputs from up to eight
power controllers.
• A 0 - 5 VDC input signal from a remote process controller, such as a PLC.
The power controller output can be turned on and off by a remote set of contacts, such as in a flow switch. 0-5
VDC output signals corresponding to the output voltage and current are available for a remote voltmeter and
ammeter to indicate the output voltage and current.
The power controller is contained on a single PC board and mounted on an aluminum chassis. The dimensions are
shown in Figure 1.
