WRT20FWX-O Description

Short technical summary and product information.

The ETA WRT20FWX-O is a 20-watt AC-DC power supply unit designed for dual output applications. It offers a primary output of +5VDC at 2A and a secondary output of -5VDC at 1A. This converter features a universal input voltage range of 100-240 VAC (85-264 VAC) and operates across a wide frequency range of 47-440 Hz.

 

Designed for reliability, the WRT20FWX-O has an efficiency of 74% typical and includes protections such as over-voltage and over-current. Its operating temperature range is -10°C to 70°C, making it suitable for various environmental conditions. The unit is enclosed and designed for chassis mounting, with dimensions of 195.0mm x 55.0mm x 27.0mm.

 

Key electrical specifications include a line regulation of 25mV max for the +5V output and 75mV max for the -5V output, with load regulation figures of 50mV max and 150mV max respectively. Ripple and noise are kept to 80mVp-p and 120mVp-p for the respective outputs. Isolation ratings are 3000 VAC for input-output, 2000 VAC for input-F.G., and 500 VAC for output-F.G.

 

This AC-DC converter is certified for CE and FCC standards, complying with IEC 60950-1 safety standards and EN55022-A for RF voltage. It comes with a 2-year warranty.
