  • Features

    The two-line alphanumeric LCD displays the operating parameters of the unit by default: the output voltage set-point and actual, output current set-point and actual and half-cell (reference electrode) voltage set point and actual. Active alarms are indicated by using the keypad and digital potentiometer; it is also used to set up other parameters, such as low current and high current alarms, auxiliary input mode and the interrupt timer.

    The CPC10A controller is available housed in painted steel, stainless steel, GRP enclosures, Exd flameproof enclosures, or can be supplied as a PCB or mounting plate assembly. The controller includes GDT and MOV protection against lightning and other induced surges.

    The CPC10A is capable of operating with any suitable DC power source. High speed PWM (pulse-width-modulated) switching technology is used to obtain high conversion efficiency. The CPC10A can operate in one of three modes: constant voltage, constant current and half-cell voltage control with automatic changeover of control mode. The half-cell input can be sampled every 60 seconds (adjustable) with the input reverting to high impedance between sampling to prevent loading of the half-cell.

    Communications & Data Logging
    The CPC10A can be supplied with the RS232 port option which includes data logging. When connected to a PC or laptop, all main parameters and the present status can be viewed. The main set points and relay settings can be uploaded, and over 10,000 timed log events downloaded. The logging period can be set to 15, 30 or 60 minute intervals. The addition of a GSM or PSTN modem allows full remote access and control. (Please note: The current communications software runs under Microsoft ® Excel ® versions 2000-2003.)
