Product details
Siemens SITOP DC UPS Module 24V/15A with Serial Interface(西门子 SITOP DC UPS 模块 24V/15A(带串行接口))
SITOP DC UPS 模块 15 串接于 24V 电源与负载之间：市电正常时经模块为负载供电并同时给电池充电,市电中断时无缝切换为电池缓冲.DIP 拨码可设定切换阈值(22.0…25.5V)与充电电流(0.35/0.7A),内置电池过放保护与输出限流;EC31 版本带 RS232 串口,可读取电池容量\缓冲时长与故障记录,便于预测性维护.满载 15A 时 3.2Ah 电池约缓冲 45 秒,7Ah 约 2 分钟.
The SITOP DC UPS module 15 sits between the 24V power supply and the load: in normal operation the load is fed through the module while the battery is charged; on mains failure it switches seamlessly to battery buffering. DIP switches set the switchover threshold (22.0…25.5V) and charging current (0.35/0.7A); battery deep-discharge protection and output current limiting are built in. The RS232 interface reads battery capacity, buffer-time and fault records for predictive maintenance. At full load (15A), a 3.2Ah battery buffers approx. 45 s and a 7Ah battery approx. 2 min.
