Price & Availability 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. Basic Product Information Integrated battery charger for external lead-acid batteries Seamless switchover to battery power during mains failure Wide input voltage range (22.5-30V DC) Comprehensive protection: overcurrent, overvoltage, reverse polarity LED status indicators for operation and fault monitoring Compact DIN-rail mountable design High efficiency and low power dissipation 20A output current for robust power bridging Technical Specifications Version & Model Difference The PVRE series includes various models with different output currents (e.g., PVRE 24/24-10 for 10A, PVRE 24/24-20 for 20A). The -20 model offers higher current capability for larger loads. Compared to newer PVRE-2 series, the original PVRE series has a simpler design with fewer communication options, but it remains a reliable and cost-effective solution for standard DC-UPS applications. Application Scenarios How does the PVRE 24/24-20 switch to battery power? The module continuously monitors the input voltage. When the input voltage drops below a set threshold (typically around 22.5V), it automatically switches to battery power within milliseconds, ensuring no interruption to the output. What type of battery should be used with this module? The module is designed for external lead-acid batteries (12V or 24V). The battery capacity should be selected based on the required bridging time and load current. The integrated charger maintains the battery at full charge. Is the PVRE 24/24-20 suitable for DIN-rail mounting? Yes, it is designed for DIN-rail mounting according to EN 60715, making it easy to install in standard industrial control cabinets. What is the purpose of the BLOCK PVRE 24/24-20? It is a DC-UPS module that provides uninterrupted 24V DC power to critical loads by bridging mains failures using an external battery. It ensures that PLCs, sensors, and other control devices continue to operate during short power outages. BLOCK PVSE 230/24-10 Power Supply (PVSE 230/24-10)
