Trio Diagram

The TRIO-PS/600DC/24DC/20 Industrial Power Supply is specifically designed for connection to high input voltages such as frequency converters. It is ideally suited for connection to 600 V DC intermediate circuits of frequency inverters. In the event of a mains line supply failure, the connected 24 V loads are supplied without interruption using the kinetic energy of the motor.

22.5 to 29.5 V DC Adjustable Output Voltage Range

Using the rotary potentiometer on the front face of the TRIO power supply, the output voltage can be optimally adjusted to meet specific application environment requirements. For example, you can easily adjust to compensate for a voltage drop caused by a long cable length.

POWER BOOST: reliably start difficult loads

Power Boots Diagram

A high degree of flexibility is required to configure, optimize and expand large systems. To optimally adapt a system or machine to your requirements, a power reserve in the power supply unit is crucial. With this TRIO Power Boost function a static boost will continuously provide up to 125% of the nominal current. This is useful when it is not possible to predict which loads will be switched on at the same time or high switch-on currents of capacitive loads have to be absorbed without voltage dips.

Preventive function monitoring reports critical operating states before they occur

Power Boots Diagram

With the TRIO-PS/600DC/24DC/20 Industrial Power Supply, the output voltage and output current are constantly monitored. Preventive function monitoring visualizes critical operating states and indicates them locally and remotely to the controller as follows:

  • Via LED
  • Via floating relay contact
  • Via active switching output

Industrial operating temperature of -25°C to +70°C

Equipment found in traffic management, oil and gas pipelines, weather tracking, industrial and outdoor applications must function in temperatures that cannot be supported by a commercial power supplies. With an operating temperature of -25°C to +70°C this TRIO Industrial Power Supply is ideal for use with equipment subjected to harsh environments and severe temperatures.

High efficiency and low no load power consumption

Compared with other products on the market, the TRIO-PS/600DC/24DC/20 Industrial Power Supply provides excellent energy savings. With a very low no load power consumption and high efficiency at nominal load, just a small amount of electrical energy is converted into undesired heat energy making these very ECO friendly power supplies.
