Title: 370.011 Siemens UC50 Kalkulator.pdf
11 Power supplyThe UC50 can be powered from a power supply module or with a battery.The lifetime of battery depends on the type of battery and on the requirements (e.g. short time base, analog module etc.).Requirements (for measuring time base Q = 4 s and measuring time base T = 30 s)6 years11 years16 yearsStandard pulses M-bus read out (max. each 15 min.), CL-Module2x AACDM-bus fast read-out, fast pulses, analog module, radio moduleD----Automatic power supply detectionThe power supply unit detects whether a line voltage is applied. This signal is routed to the UC50. That enables the device to detect automatically whether it is being powered from a battery or power supply unit.Power supply modules24 V ACDC Pollution degree110 V AC, 230 V AC per EN 61010 (no or only dry, nonAmbient temperature Storage temperature Back-up time during power failure (power reserve)conductive soiling) + 5...+ 55°C - 20 + 60°C > 20 minutes
