RS Components (RS) has announced the availability of a new series of AC-DC embedded switch-mode power supplies (SMPS) from TDK-Lambda. The cost-effective RWS-B series of AC-DC industrial power supplies comprises 10 models, each coming with an isolated 5 V 1 A standby voltage option. 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 5 V standby voltage kicks in even when the main output is inhibited or is in overvoltage or overcurrent condition. This low power output allows 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 1000 W (RWS1000-B) or 1500 W (RWS1500-B) output power, the series has a universal 85 to 265 V AC input range and includes devices with 12 V, 15 V, 24 V, 36 V and 48 V 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 63 mm with a height of 198/261mm for the 1000 W/1500 W 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. Offering a long service life, 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.
