Space saving power supplies with diagnostic capabilities
RS Components has announced availability of a range of DIN rail power supplies from Siemens, which are suited to a wide range of industrial automation applications.
Designed for use in distributed power applications in machine control boxes or in small cabinets, the single-phase SITOP PSU6200 power supplies are slim and space-saving, with plug-in terminals that support easy electrical connection. A key feature of the series is its very low power loss across the entire load range, especially in idle mode, which makes the units ideally suited for automated machines in plants that are often in standby operation.
Featuring wide-ranging DC-compatible input voltages from 85 to 275V AC or 99 to 275V DC, the series delivers output DC voltages from 12 to 15.5V at 2A, 7A, 12A, or 24 to 28V at 1.3A, 2.5A, 3.7A, 5A, 10A, 20A (depending on model). Overall, the characteristics, in conjunction with the series’ wide operating temperature range, means they can be deployed in multiple industrial application options.
Another key feature of the series is the integration of advanced diagnostic capabilities, enabling the units to indicate their operating status and current utilisation, as well as end-of-service life via LEDs. They also output a serial code via the diagnostics interface, which can be read via a digital input on a PLC and evaluated by a function block.
Status and operating parameter information includes: DC ok; utilisation percentage levels; remaining service-life warning – for a value below 10%; output current and voltage to 1A and 0.1V resolutions, respectively; and device temperature warnings.
