Overview
The Triad WAU200-600 is a wall plug-in AC power supply intended for use as an external power source across a wide range of equipment and devices. It delivers 20 V AC at 600 mA, with a rated output of 12 VA, from a 120 V, 60 Hz North American mains input. Output voltage tolerance is ±5%, and the no-load secondary voltage is held to less than 25.0 V. The unit carries a Class 2 UL power supply rating and is listed under UL/cUL file E341931 per UL 1310, making it suitable for applications requiring certified, current-limited AC power delivery.
This supply meets DOE/CEC Efficiency Level VI requirements, with a measured average efficiency of 82.96% and a standby no-load power consumption of no more than 0.21 W. These characteristics suit designs subject to energy efficiency regulations in North American markets. The operating temperature range of -10 to +40 °C, combined with a maximum enclosure surface temperature rise of 45 °C at rated load, supports deployment in typical indoor environments. The supply also meets RoHS (2011/65/EU) requirements.
The Triad WAU200-600 is housed in a thermoplastic molded enclosure measuring 79.6 mm x 59.7 mm x 48.1 mm (H x W x D) and connects directly to a standard North American wall outlet. The output is provided via a 5.5 x 2.1 mm barrel connector on a 24 AWG cord with a minimum length of 6 ft. Before selection, designers should confirm that the AC output type is appropriate for their application, verify connector polarity and load current requirements against the 600 mA rating, and ensure the operating environment falls within the specified temperature limits.
