Product Description
It ensures continuous operation of critical loads during mains failures or voltage dips, making it essential for industrial automation, process control, and safety systems. With an output current of 20A, it supports a wide range of applications, from PLC systems to drives and sensors. This module operates with a nominal input voltage of 24V DC and delivers a regulated 24V DC output. It features an integrated charging circuit for external batteries (typically lead-acid or similar), allowing seamless transition to battery power when the input voltage falls below a set threshold. The PVRE series is known for its robust design, high efficiency, and compact DIN-rail mounting, simplifying installation in control cabinets. The PVRE 24/24-20 includes comprehensive protection features such as overcurrent, overvoltage, and reverse polarity protection, ensuring safe operation in demanding industrial environments. Its LED status indicators provide clear visual feedback on operating states, including mains operation, battery operation, and fault conditions. With a wide operating temperature range and compliance with international standards, this module is a trusted choice for OEMs and system integrators. The BLOCK PVRE 24/24-20 is a DC-UPS (uninterruptible power supply) module designed to provide reliable bridging and buffering of 24V DC control circuits.
