Power Supplies

A DC stabilized power supply is an essential device for supplying a stable DC voltage to a variety of electronic devices and circuits. In particular, its ability to maintain a constant voltage regardless of voltage fluctuations or load changes makes it extremely important for the operation of precision electronic devices.

  • PS-A / PS-AR Series Regulated DC Power Supplies

    ● Four digits LED display
    The high resolution display can indicate output voltage and current and power value. Voltage and current values can be easy to set with "digit key" by selecting a digit to be changed.
    ● Three points preset memory function
    Possible to preset three kinds of voltage and current values inside for easy reading of setting values.
    ● HI-R Function
    This function is useful for not to discharge secondary cell, not to ungild plating and so on.
    ● Off timer function
    Possible to turn off output automatically after a lapse of preset time.
    ● Controlling transient build-up current function
    This function enables to control current at output on and prevents current overshoot.
    ● Sequence function
    Stand-alone sequence operation is possible by loading maximum 1000 steps sequence program from PC into the unit through optional IF-70GU or IF-70RS interface board.
    ● Master slave operation
    This function enable to operate plural same units in parallel up to 2400W (up to 800W for 6V series) and in series for two units.
    ● External analog control (PS-A type only)
    The PS-A series can be controlled by external voltage or resistance for setting voltage and current values and by external contact for turning on/off output and selecting preset memory. PS-AR type dose not accommodate external analog control.
    ● Optional remote control interface boards
    IF-70GU (GP-IB and USB), IF-71RS (RS-232C) and IF-70PS (compatible with PS series) are available.
    ● RS-232C standard PS-AR type
    PS-AR type is included RS-232C control board. PS-AR type can connect max. 32 units and be controlled by PC. Simple and low-cost system can be provided.
