Power supply variants

  • JBZ-02 variant

    The basic variant has been designed for systems where supply voltage has been determined from Mains AC power network voltage (Um = 250V). JBZ-02 can be powered from AC power supply with charged accumulator back-up. JBZ-02 variant features a galvanic separation circuit between input and intrinsically safe output.

    JBZ-02/A variant

    JBZ-02/A variant has been characterized by reduced internal power consumption. This feature makes possible to use a power supply with systems powered by accumulator charged by solar panel (Um = 60V). This variant does not have a galvanic separation circuit between input and intrinsically safe output. For this reason, neither JBZ-02/A or back-up accumulator can be connected to power sources which are determined from the Mains AC power network (Um = 250V).
