New RWS1000B and RWS1500B AC-DC Power Supplies Come with Double Sided Board Coating

Press Release Summary:

The RWS1000B and RWS1500B AC-DC Power Supplies are offered with 12, 15, 24, 36 and 48V main outputs and are rated at 1000 W and 1500 W. The devices feature reverse airflow operation, remote on/off, current share and an isolated DC good/fan fail signal. They are suitable for applications such as industrial, broadcast, communications and LED signage equipment. The RWS1000B and RWS1500B are available in 127 x 63 x 198 mm and 127 x 63 x 261 mm respectively and meet EMC, RoHS, CL and UL/CSA/EN 60950-1 standards.

Original Press Release:

1000W and 1500W Power Supplies Have Optional 5V Standby Outputs

TDK Corporation (TSE 6762) announces the introduction of an isolated 5V 1A standby voltage option to the RWS1000B and RWS1500B industrial AC-DC power supplies. Applications include industrial, test & measurement, broadcast, communications and LED signage equipment.

Rated at 1000W and 1500W the additions are available with 12, 15, 24, 36 and 48V main outputs and can accept an 85 to 265Vac 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 +70oC 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.
