Phoenix Contact TRIO-PS-2G/3AC/24DC/5 Power Supply 3-phase

TRIO-PS-2G/3AC/24DC/5: three-phase 24 V DC 5 A supply

The Phoenix Contact TRIO-PS-2G/3AC/24DC/5 (order no. 2903153) combines a three-phase input with a modest 5 A output at 24 V DC. It is 35 mm wide, 130 mm high and 115 mm deep, with push-in terminals. The nominal input range is 3 x 400 to 500 V AC, with -20 % and +15 % tolerance, and the datasheet also lists two-phase operation.

Seven Star LLC supplies the TRIO-PS-2G/3AC/24DC/5 as an independent supplier in Muscat for projects in Oman and the GCC, quoted against the exact part number shown here.

Technical specifications of the TRIO-PS-2G/3AC/24DC/5

How the TRIO-PS-2G/3AC/24DC/5 works

The TRIO-PS-2G/3AC/24DC/5 is a primary-switched supply from the TRIO POWER 2nd generation (the 2G in the type code). Mains input is converted to an isolated, regulated DC output through a high-frequency stage. The datasheet lists a dynamic boost, an output power figure that can be drawn for a few seconds above nominal, which helps with start-up peaks of motors, solenoids and capacitive loads. A DC OK signal on a changeover contact and an LED report the status of the output, so a controller can see when the supply is healthy.

Efficiency is above 91.1 % at 400 V AC, typically 90.9 % at 480 V AC. Output power is 120 W with 180 W for 5 seconds.

Where the TRIO-PS-2G/3AC/24DC/5 fits in a system

TRIO POWER sits between the compact STEP POWER range and the more advanced QUINT POWER range: it gives a robust metal-housing supply, wide temperature range down to -25 degrees C, and a status contact, without the NFC configuration and selective fuse breaking of QUINT4. It is a typical mid-range choice for machine builders and panel shops who want proven performance at moderate cost.

The TRIO-PS-2G/3AC/24DC/5 is for installations where only 3-phase supply is available at the panel, for example drive cabinets and motor control centres, and a small 24 V supply is needed for the control logic.

Selection and ordering checklist

• Confirm the nominal output voltage and current of the TRIO-PS-2G/3AC/24DC/5 against the load total, leaving a reserve.
• Check input voltage and number of phases against the site supply.
• Note the dynamic boost power if the loads have a start-up peak.
• Compare the housing width and depth with the available rail space and cabinet door clearance.
• Check that the ambient temperature does not exceed the derating limit of 60 degrees C for continuous full load.
• Decide whether the status contact will be wired to a controller.

Installation, commissioning and maintenance of the TRIO-PS-2G/3AC/24DC/5

Mount the TRIO-PS-2G/3AC/24DC/5 on a 35 mm DIN rail with the clearances shown on the datasheet, connect the input and output to the labelled terminals and fit the status wiring if it is needed. Set the output voltage with the potentiometer, check the polarity at the loads and confirm that the DC OK LED lights before closing the cabinet.

Take the output current rating from the table and apply the derating shown for temperatures above 60 degrees C. After commissioning, retighten terminals once the unit has seen a thermal cycle and keep the vents clear of dust.

Typical applications in Oman and the GCC

In Oman and the GCC, control cabinets often run at high ambient temperatures, so the operating range and derating curve in the table are what decide whether a supply is suitable. These supplies are used in oil and gas skids, water treatment and desalination plants, power substations, petrochemical packages and building automation panels.

In GCC industrial plants, where motor control centres use 400 V three-phase, this type avoids a separate single-phase transformer.
