Helios RWS1000B and RWS1500B industrial power supplies

Helios has added the RWS1000B and RWS1500B industrial AC-DC power supplies. The power levels of 1000 and 1500 W will complement the existing RWS300B (300 W) and RWS600B (600 W) supplies. The series is suitable for industrial, test and measurement, broadcast, communications and LED signage equipment.

The 1000 and 1500 W additions are available with 12, 15, 24, 36 and 48 V outputs, adjustable from -15/+10% of nominal. All models accept an 85 to 265 VAC input and can operate at full load in -20 to +50°C ambient temperatures, derating linearly to 60% load at +60°C. High operating efficiencies of up to 88% reduce internal waste heat and component temperatures, resulting in electrolytic capacitor service life predictions of at least 10 years.

To facilitate safe and easy installation, output cable connections are made to screw terminal blocks with covers rather than busbars. The terminal block can also be quickly configured for either a vertical or horizontal wiring orientation. The RWS1000B measures 127 x 63 x 198 mm and the RWS1500B 127 x 63 x 261 mm.

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.
