1.2 General Description
The DC power controller IP-POWER600-G2 was designed specifically as a component of a DC
power supply used with continuous electrodeionization (CEDI) modules manufactured by Ionpure
.
This unit can be used with the MX, LX and VNX lines of CEDI modules.
The controller is designed for operation in constant current mode. In constant current mode, the
output current is maintained at the selected value, regardless of the load resistance, while the
voltage varies. As the resistance increases, the required voltage also increases.
NOTE: When the required voltage reaches the maximum possible DC voltage (90% of the RMS
AC input voltage), it cannot increase further. If the resistance continues to increase, the
output current must decrease.
The unit is rated for 50/60 Hz, has an input voltage range of 220 to 660 VAC, and has an output
voltage range of 30 to 600 VDC. The unit can deliver a maximum output current of 13.2 amps DC.
The unit has five selectable DC output current ranges: 0 to 2.5 A, 0 to 4.0 A, 0 to 6.5 A, 0 to 10.0 A
and 0 to 13.2 A. Each current range may be selected with an on-board DIP switch.
NOTE: In order for the unit to operate properly, there must be an appropriate resistive load
connected to the DC output. If the unit is operated without a load, then the unit will
remained powered on but there will be no DC output. This fault condition will be
indicated by the on-board LEDs as described in Section 4, Table 2.
There is no energy storage within the unit, such as electrolytic bulk capacitance. Therefore, the
output appears as unfiltered DC power with an AC power component, which is acceptable for its
intended use in electrodeionization. The unit contains no formal power factor corrector, but it will
