An isolated 5-V, 1-A standby voltage option is now available for the RWS1000B and RWS1500B industrial ac-dc power supplies. Applications include industrial, test & measurement, broadcast, communications and LED signage equipment.

Rated at 1,000 W and 1,500 W the additions are available with 12, 15, 24, 36 and 48-V main outputs and can accept an 85 to 265 Vac input. The standby voltage option is required if key circuitry has to be kept active when the main high-power output is inhibited for energy saving purposes, or during an overload condition. This avoids the necessity for an often lengthy hard system re-start.

Other options for the power supplies include double sided board coating, reverse airflow (which extends operation to +70°C ambient temperatures), remote on/off, current share and an isolated dc Good/Fan Fail signal. A seven-year warranty is provided as standard.

All TDK-Lambda RWS-B 1000 and 1500W models are certified to the safety standards of UL/CSA/EN 60950-1 (62368-1 in process) and are CE marked in accordance to the Low Voltage, EMC and RoHS Directives. All models offer curve B conducted and radiated performance to EN55011/EN55032-B, meet EN 61000-3-2 harmonics, IEC 61000-4 immunity and SEMI F47 line dip standards.
