    OUTPUT SPECIFICATIONS (each output)

    Voltage/Current/Power Levels

    VoltageRange: 0V to 60V.
    CurrentRange: 0A to 20A.
    Note: Actual maxima for voltage and current are typically 1% greater than the figures given above.
    PowerRange: Up to 420W per output subject to power envelope.

    Power Envelope

    The maximum current at any voltage settings is limited by the power envelope which is set to give 7A at 60V rising to 20A at 20V under all ac supply conditions (both outputs loaded). At lower output voltages the power is restricted by the 20 amps current maximum.  See PowerFlex power envelope graph

    Output Setting & Control

    Voltage Setting: By coarse and fine controls.
    Current Setting: By single logarithmic control.
    Output Mode: Constant voltage or constant current with automatic cross-over. CC indicator for constant current mode.
    Output Switch: Electronic, non isolating. Preset voltage and current limit displayed when Output is off. 
                           Output rise time no load <10ms.
    View Settings: With the output On, the meters show actual voltage and current. The preset levels can be viewed and
                          adjusted at any time by pressing the View Settings button.
    Status Indication: LED indication of Output On, V/I Limits, CV, CI, Power Limit, Remote, LAN status. 
                              Message on meter display for trip condition.

    S-Lock (Settings Lock)

    Voltage and current settings can be locked by a single button press. Lock accuracy is equal to the meter accuracy (see Meter Specifications).

    Output Performance

    Ripple & Noise: Typically <3mV rms, <15mV pk-pk, in CV mode.
    Load Regulation: Voltage - <0.01% of maximum output for any load change within the PowerFlex envelope. 
                             Current - <0.05% of maximum output for any load change within the PowerFlex envelope.
    Line Regulation: Voltage - <0.01% of maximum output for a 10% line change.
                            Current - <0.01% of maximum output for a 10% line change.
    Transient Response: <250us to within 50mV of setting for a 5% to 95% load change.
    Temp. Coefficient: Typically <100ppm/oC

    Output Protection

    Output Protection: Forward protection by Over-voltage Protection (OVP) trip. 
                                Reverse protection by diode clamp for currents to 3A.
    OVP Setting/Range: Via screwdriver adjustable preset on front panel. Range 1V to 66V
    Over-temperature: Output trips off for over-temperature.
    Safety Interlocks: Operations that could cause an unexpected change in voltage or current settings are interlocked
                               with the output switch.

    Output Connections

    Power Terminals: Universal 4mm safety binding posts on 19mm (0.75") spacing at front. 
                               Screw terminals at rear (CPX400SP, SA and DP only).
    Remote Sense
    Sense Selection: Voltage sensing is selected as Local or Remote by front panel switch.
    Sense Terminals: Sprung loaded screw-less terminals at front. Screw terminals at rear (CPX400DP only).

    METER SPECIFICATIONS (each output)

    Display Type: Dual 4-digit meters, 10mm (0.39") LED.
    Voltage Meter
    Resolution/ Accuracy: 10mV; +/- 0.1% of reading +/- 2 digits
    Current Meter
    Resolution/ Accuracy: 10mA ; +/- 0.3% of reading +/- 20mA

    VOLTAGE TRACKING (Dual output models)

    Independent Mode
    In the normal mode of operation, each output is fully independent and isolated. Operation is equivalent to two single output power supplies.
    Voltage Tracking Mode
    The two outputs remain isolated, but the Slave voltage controls are disabled and the Slave voltage is set equal to the Master voltage. This can be used to generate tracking bipolar voltages, or tracking unipolar voltages relative to different grounds. 
    When voltages greater than 60V are required, the outputs can be wired in series to generate 0 to 120V with the voltage controlled from the Master.
    When currents greater than 20A are required, the outputs can be wired in parallel to create the equivalent of a 40A power supply with the voltage controlled from the Master.
    Track Accuracy: Slave voltage = +/- (0.1% of Master voltage setting + 10mV)

    BOTH ON / BOTH OFF (Dual output models)

    Each output has an independent DC On/Off control, however, an additional control button is provided which turn both outputs on or off simultaneously.

    DIGITAL BUS INTERFACES (CPX400SP and CPX400DP only)

    These models offers full remote control and read-back using RS-232, USB, GPIB or LAN (compliant with LXI class C).All interfaces are at ground potential and opto-isolated from the output terminals. Note: Remote/Local Sense, is manually selectable only.
