1000W and 1500W AC-DC Power Supplies Have Optional 5V Standby

TDK Corporation has announced the introduction of an isolated 5V 1A standby voltage option to the RWS1000B and RWS1500B industrial ac-dc power supplies. Applications are expected to include industrial, test and measurement, broadcast, communications and LED signage equipment.

Rated at 1000W and 1500W the additions are available with 12-, 15-, 24-, 36- and 48-Vdc 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.
