Primary voltage: 230V or 400V
Secondary voltage: 24V or 48V
Safety isolating design
Professional industrial grade
How to use
Installation should be performed by a qualified electrician in accordance with local electrical regulations. The transformer must be mounted securely within a ventilated enclosure to ensure proper heat dissipation. Connect the primary supply wires to the appropriate terminals based on your input voltage (230V or 400V) and connect the secondary load to the 24V or 48V terminals as required. Ensure all connections are tightened to the specified torque and that the system is properly grounded before energizing.
What to consider before purchase
Verify that the 160VA power rating is sufficient for your specific load requirements.
Ensure the input voltage of your supply matches the 230V or 400V configuration.
Check that the required secondary voltage (24V or 48V) matches your equipment specifications.
Confirm that the installation space provides adequate ventilation for the transformer.
Usage recommendations
Regularly inspect the terminal connections for tightness and ensure the transformer remains free of dust and debris to maintain optimal cooling and performance.
