Phoenix Contact’s IP67 Power Supplies: Providing Power Where Needed

Phoenix Contact has expanded its existing power supply solutions with the addition of the TRIO IP67 power supplies. The new power supplies can be mounted directly on machines and in the field next to devices that require constant DC power, enabling decentralization.

DC Power Supplies

With most automation devices using DC power, finding multiple AC to DC power supplies within a control cabinet is common. The incoming AC voltage is filtered for voltage fluctuations within the power supply and converted to a constant DC output, typically 24 VDC. This voltage is then used to power sensors, control contactors and relays, and provide signals to the control system. 

 

Decentralizing Power

Many automation component manufacturers are producing components that allow designers to decentralize their designs. If devices are not IP67-rated, they typically cannot be installed in the field—they will need to be installed within a NEMA-rated electrical cabinet. This limitation creates a centralized location for most electrical components. 

Decentralization is possible with IP67 and IP68-rated I/O blocks, power supplies, and servo motor drives. These devices can be installed in the field where they are needed, allowing designers to reduce the overall space required in the control cabinet.

TRIO IP67 Power Supplies

Phoenix Contact’s new TRIO IP67 power supplies are designed to be installed on machines or in the field for powering small-load devices. Instead of long runs of cables carrying DC voltage, more efficient power can be used and transformed into usable power. The number of power supplies used within the control cabinet can also be reduced using the TRIO IP67, saving space and allowing for smaller control cabinet design practices. 

The TRIO is offered in a single-phase input with either 24 VDC / 8 A output or 24 VDC / 10 A output. Each TRIO is equipped with a dynamic power boost that allows the load on the system to draw up to 150% for 5 seconds. Inductive and heavy starting loads will benefit the most from this feature. Each model also has a set of 0 VDC and 24 VDC within the single connector, allowing the power supply to handle two different circuits in unison.

Flexible Mounting and Connection 

Unlike typical power supplies, the TRIO IP67 does not have DIN rail mounting features. Instead, it has flanged edges with mounting holes. The power supply can be mounted in any direction to facilitate easy access to the electrical connections.

There are three connections on the front of the unit: one for incoming AC voltage, a connection for a DC OK dry contact, and the output connection with two channels. The TRIO comes in three connection variations: M12, ⅞”, and installation power distribution (IPD). Both the M12 and the IPD models are offered in 10 A versions, while the ⅞” model is only available in 8 A. 

Two LEDs on the front of the unit indicate if the incoming AC voltage and the DC output voltage are OK. The monitoring connection allows a control system to monitor the DC output health and alert operators if a problem arises.
