50-Watt AC-DC power supplies for test and communications introduced by TDK Lambda
SAN DIEGO, 19 Aug. 2014. TDK-Lambda Americas Inc. in San Diego is introducing 50-Watt versions of the RWS-B series of AC-DC power supplies for industrial, test & measurement, broadcast, communications, and LED signage applications.
The 50-Watt RWS-B power supply is designed to provide solid performance at an economical price, company officials say. The product line has five power levels and compact case sizes, including 100-, 150-, 300-, and 600-Watt versions.
The RWS-B operates from a universal input of 47-63 Hz, 85-265 volts AC (300 volts AC for 5 seconds), and is available with nominal outputs of 5, 12, 24, and 48 volts DC with an adjustment range of a minimum of +/-10 percent.
The convection-cooled 100- and 150-Watt models operate from -10 to 70 degrees Celsius with derating above 40 C and the fan cooled 300 and 600 Watts models to 70 C with derating above 50 C. In addition over voltage and over current protection is included.
High operating efficiencies of to 89 percent reduce internal waste heat and component temperatures, resulting in electrolytic capacitor service life ratings of at least 10 years.
The TDK-Lambda RWS-B series is certified to the safety standards of UL/CSA 60950-1, UL508 (on certain models), is CE marked according to the Low Voltage, RoHS2 Directives, and additionally evaluated to EN 60950-1. All models offer curve B conducted and radiated performance to EN55011/EN55022-B, FCC class B and VCCI-B.
