      FAQ

      View All Faqs
      • What components are included in the 1756-PAR2 assembly and how do they interoperate?
        The 1756-PAR2 assembly comprises two 1756-PA75R power supplies, two 1756-CPR2 connecting cables, and a 1756-PSCA2 chassis adaptor. Together, these elements form a fully integrated redundancy system that interfaces with the ControlLogix chassis to ensure uninterrupted power distribution across the backplane.
      • What input voltage range does the 1756-PAR2 support for AC mains power, and how does this range facilitate industrial integration?
        The 1756-PAR2 supports a broad AC mains input range of 85–265 VAC (47–63 Hz), enabling compatibility with global power standards and robust performance in diverse industrial environments where line voltage may vary significantly
      • How does the 1756-PAR2 establish power redundancy, and what benefits does this bring to mission-critical ControlLogix deployments?
        The 1756-PAR2 establishes redundancy by paralleling two independent power supplies within a single assembly. If one supply experiences a fault or interruption, the other maintains backplane power, minimizing control system downtime and enhancing availability in high-uptime or safety-critical applications.
      • What isolation and safety characteristics are inherent to the 1756-PAR2 design?
        The 1756-PAR2 exhibits 250 V continuous reinforced insulation between key domains (e.g., power input to backplane and annunciator), and has been tested to 3250 V DC for 60 s for enhanced dielectric robustness, helping to reduce the risk of electrical faults affecting system integrity.
      • How does the 1756-PAR2 perform with respect to inrush current and hold-up time during power disturbances?
        The 1756-PAR2 supports a maximum inrush current of approximately 20 A on startup, and can maintain output hold-up for two AC cycles at both 50 Hz and 60 Hz line frequencies, offering short-term power resilience during transient power disturbances.
