SITOP - At the heart of automation
Thanks to their high degree of reliability, SITOP power supplies have established themselves around the world and can cope with even critical network conditions. Our complete range of power packs supplies regulated 24 volts and other output voltages. The unique range of DC UPS and add-on modules extends the power supply system: 24 V supplies are thus protected against interference from the grid and on the direct voltage side.
Add-on modules
Add-on modules for increasing system availability
A power supply unit on its own cannot guarantee fault-free 24 V supply. Power failures, extreme line voltage fluctuations, or a faulty load can disrupt plant operation and result in high costs. The add-on modules offer everything from extensive protection against interference on the primary and secondary side right up to complete all-round protection.
SITOP RED1200 redundancy module Input/output: 24/48 V DC/20 A Suitable for decoupling two SITOP power supplies with max. 10 A output current each

An expansion module used to improve system availability and provide comprehensive protection. The quality of the power supply device alone cannot guarantee the provision of a 24V power supply without any faults. Power failure, significant changes in power supply voltage, or load failure can all cause the device to stop running, resulting in higher costs. Therefore, processes and devices that are crucial to a company's business often require additional protective measures. The SITOP add-on module can provide protection for production against potential hazards on the primary and secondary sides, and can comprehensively and flexibly expand SITOP power equipment to achieve comprehensive protection.
