The Siemens 6EP1935-6MD11 is a robust SITOP battery module designed to provide reliable backup power for SITOP DC UPS modules rated at 6 A and 15 A. This maintenance-free, sealed lead-acid battery module is an essential component for industrial automation systems, ensuring operations continue smoothly during power disruptions.
With a 24 V DC output and a capacity of 3.2 Ah, it is engineered to meet the demands of a wide range of applications. The battery module is equipped with spring-loaded terminals for secure and straightforward electrical connections, and it can be easily installed onto a DIN rail or mounted using keyhole slots for M4 screws, providing flexibility in system integration.
The 6EP1935-6MD11 operates effectively within a broad temperature range from -15°C to +50°C, making it suitable for challenging industrial environments. It also features a solid-state circuitry fuse of 15 A to protect against overcurrent conditions, ensuring the longevity and safety of both the battery and the connected equipment.
This battery module is designed with longevity in mind, offering a typical service life that sees capacity fall to 80% of the original after 4 years at 20°C, with proportional reductions at higher temperatures. To maximise its service life, it is recommended to store the battery fully charged and within a temperature range of 0 to +20°C when not in operation.
