The PBX Series Bipolar Power Supplies are regulated power supplies of a bipolar-type, featured by performance reliability and safety. They employ a power amplifier system, thereby rendering advantageous features such as low ripple noise, high stability, and rapid response. Being a 4-mode type, they serve also as a source or a sink of power, or as a booster of a function generator. They are microprocessor-based instruments and provide advanced functions and ease of operation. Each of them can operate either in a constant-voltage mode (C. V mode) or in a constant-current mode (C.C mode), mutually independently. This allows you to use them also as a constant-current source or as a volt-age-controlled current source. You may remote-controlled them via an optional GPIB, RS-232C, or MCB(Multi-channel Bus) interface, thereby making them applicable to various purposes. Typical applications are for research systems in laboratories and for automatic production and inspection lines in manufacturing plants.
