TRIO general-purpose power supplies feature a rugged, zinc-plated steel housing that measures between 32 mm and 115 mm wide. The power supplies address applications requiring 2.5A to 20A of 24VDC power and feature the same output regulation as the company's Quint, Mini, and Step power supply products. In accordance with IEC 61709, the products have a mean-time-between-failure (MTBF) rating of more than 500,000 hr. In addition, they operate in temperatures ranging from 0°C to 70°C and offer a 55°C nominal operating temperature without de-rating. Other product features include a built-in LED diagnostic indication, adjustable 2.25VDC to 29.5VDC output, and three DC grounding terminals.

Portable PDUs

The PowerWeb product line includes five indoor and five outdoor portable power distribution centers ranging from 30A to 100A for generators and temporary power hookups from 7,500W to 25kW. Each device features a rugged “sled” frame and a corrosion-resistant aluminum enclosure with powder-coated lid in a high-visibility green color. Each receptacle includes an individual GFCI that monitors the receptacle and trips only the affected one when an open neutral or reverse polarity fault condition is detected. Outdoor models include heavy-duty, metal, while-in-use bubble covers for weatherproof cord protection. Locking outlets are included to allow users to daisy chain multiple models together.

Power packs

The Universal Voltage Power Pack (UVPP) and Universal Voltage Power Pack with Manual On/Off Control (UVPPM) automatically detect input line voltage from 100VAC to 277VAC. Both power packs are capable of switching 20A loads and feature zero arc point switching technology that, according to the company, minimizes relay contact wear associated with high rush inloads. The UVPPs supply power for up to four sensors and can be used with the company's auxiliary relay device (MPSA) to control multiple circuits. In addition, the UVVPM control works with low-voltage momentary switches and is suitable for applications where users require manual on/off and automatic off control.
