Robust embedded power supplies exclude hard system restart

This latter feature makes the series suitable for markets including industrial, communications, test and measurement, LED signage equipment, and alternative-energy applications.

Importantly, the additional isolated 5V standby voltage kicks in even when the main output is inhibited or is in overvoltage or overcurrent condition.

This low-power output means the supply of an additional voltage to keep key circuitry active during an energy-saving ‘sleep’ mode or during an overload condition – thereby avoiding a complete hard system restart.

Offering either 1000W (RWS1000-B) or 1500W (RWS1500-B) output power, the series has a universal 85 to 265V AC input range and includes devices with 12V, 15V, 24V, 36V and 48V DC outputs.

Other features of the series include: remote on/off; current share; an isolated DC Good/Fan-Fail signal; and reverse airflow – which can extend operation in ambient temperatures up to +70ºC.

Unit dimensions are 127 x 63mm with a height of 198/261mm for the 1000W/1500W models, respectively.

All the units are certified to the IEC/EN/UL 60950-1 safety standards with CE marking for the Low Voltage, EMC and RoHS2 EU Directives.

The units also comply with EN55011-B and EN55032-B for conducted and radiated emissions and meet the EN61000-3-2 harmonics and IEC61000-4 immunity standards.

Offering a long-service life, the RWS1000/1500-B series is shipping now from RS in the EMEA and Asia Pacific regions, and comes with a seven-year warranty as standard.
