Standby voltage option added to industrial power supplies

TDK Corporation has introduced ten models with a 5V 1A standby voltage option to the TDK-Lambda brand RWS1000B and RWS1500B series of AC/DC industrial power supplies. This new feature is ideal for general industrial, test and measurement, communications and alternative energy applications. Rated at 1000W and 1500W output power, the units are offered with 12V, 15V, 24V, 36V and 48V outputs. The isolated 5V standby voltage is present even when the main output is inhibited or in an overvoltage or overcurrent condition. This low power output can be used as an extra voltage or to keep key circuitry active through an energy saving ‘sleep’ mode, to avoid a complete system re-start. Also, the standby voltage of the power supplies can also be ordered with double-sided board coating, remote on/off, reverse airflow, single wire current sharing and DC good and fan alarm signals. The units are safety certified to IEC/EN/UL 60950-1 with CE marking for the Low Voltage, EMC and RoHS2 Directives. The units also comply with EN 55011-B and EN 55032-B conducted and radiated emissions, and meet the EN 61000-3-2 harmonics and IEC 61000-4 immunity standards.
