Datasheet

TDK has announced the introduction of 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 suitable for general industrial, communications, test and measurement and alternative energy applications.

Rated at 1,000W and 1,500W output power, the units are available with 12, 15, 24, 36 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 additional voltage or to keep key circuitry active during an energy saving ‘sleep’ mode - avoiding a complete system re-start.

In addition to the standby voltage, the 1,000/1,500W RWS-B power supplies can also be ordered with double sided board coating, reverse airflow, remote on/off, 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.
