7054 & 7055 High Voltage Adjustable Power Supply Modules

  • Precision linear regulated DC power supplies with high power density and smart analog controls for voltages up to 120V (7054) or 250V (7055).

    Comprehensive features include:

    • Linear regulation: ultra-low output noise and fast transient recovery
    • High power density: 90 watts per output from the 7054 and 94 watts per output from the 7055
    • Higher precision: Exceptional line and load regulation; easy-switch remote sense
    • Better metering: High accuracy four digit fixed-resolution meters; low current range; current meter averaging
    • True analog controls: Quick and intuitive adjustment of voltage and current
    • Digital convenience: Unique S-Lock and V-Span functions
    • See exactly what's happening: DC output switch - check your settings before applying them; 'view settings' button - check and adjust limits at any time
    • Safe and secure to use: Lockable voltage and current settings (using S-Lock); connect via safety binding-post terminals.
    • Programmable versions 7054P and 7055P: Includes all of the manual control features, but adds comprehensive remote control facilities. RS-232 and USB interfaces.

    Output

    Voltage/Current Ranges

    7054 - 0 to 120V / 0.01mA to 750mA (90W max.)
    7055 - 0 to 250V / 0.01mA to 375mA (94W max.)
    Note: Actual maxima for voltage and current are typically 1% greater than the figures given above except for the voltage control on the 7055 which is limited to 250.0V

    Output Setting & Control

    Voltage Setting: By coarse and fine controls.
    Current Setting: By single logarithmic control.
    Low Current Range: Reduces max. current to 75mA and increases resolution to 0.01mA.
    Output Mode: Constant voltage or constant current with automatic cross-over. CC indicator lit in constant current mode.
    Output Switch: Electronic, non isolating. Preset voltage & current limit displayed when Output is off. Output rise time no load <20ms.
    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.

    V-Span
    (Voltage Span Control)

    Voltage adjustment range can be controlled by digital setting of the end-stop values of the coarse voltage control to any desired values. The range for Vmax is 1V to 120V or 250V depending on model. The range for Vmin is 0 to (Vmax – 1V).

    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 Specification).

    Output Performance

    Ripple & Noise: Normal mode voltage: <2mV rms and 10mV p-p. Normal mode current: <10uA rms ; <1uA rms on 75mA range. Common mode current: <20uA rms
    Load Regulation: Voltage <0·01% + 10mV. Current - typically 0·01% + 50μA.
    Line Regulation: Voltage <0·01% + 10mV for 10% line change. Current <0·01% + 50μA. for 10% line change.
    Transient Response: <250μs to within 50mV of setting for a 90% load change.
    Temp. Coefficient: Voltage: typically <(50ppm + 2mV)/°C Current: typically <(100ppm + 0.1mA)/°C; <(100ppm + 0.01mA)/°C on 75mA range.

    Output Protection

    Output Protection: Output will withstand forward voltages of up to rated output voltage. Reverse protection by diode clamp for currents to 3A.
    OVP and OCP Trips: Voltage or current measured to be in excess of 105% of the rated maximum will cause the output to trip off.
    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

    Output Terminals: Universal 4mm safety binding posts on 19mm (0.75") spacing. Terminals can accept fixed shroud 4mm plugs, standard 4mm plugs, fork terminals and bare wires. 

    Remote Sense

    Sense Selection: Voltage sensing can be selected as Local or Remote by front panel switch.
    Sense Terminals: Sprung loaded screw-less terminals.
