Turck PSU67 series switched-mode power supply

Turck has announced a 24 V switched mode power supply with IP67 protection for installation directly in the field. A large amount of expensive cabling with large cross-sections is required if the field device and the control cabinet for the plant are large distances apart. The use of power supply units with IP67 protection is particularly suitable here, as they provide a 24 V power supply directly in the field without any voltage drop. Due to their degree of protection to IP67, the PSU67 power supply units can also be fitted directly to the machine without any protective measures.

The power supply units offer a high level of fail-safe performance, due to their no-load and short-circuit protection as well as passive air cooling. The devices also automatically bridge voltage dips of up to 50 ms. The high efficiency of the devices ensures a good energy balance of up to 90%. The AC/DC wide range input and an ambient temperature range from -25 to +60°C make the power supply units suitable for worldwide use. They feature a voltage output with a 4-pin 7/8″ connector. LEDs indicate the actual operating state to the user.

The switched-mode power supply units are available in four variants: a 2 A, a 4 A and an 8 A variant, each with one output, and a variant with two 4 A outputs. The power supply units are compliant with the requirements of EN 60950-1 and have cULus and CE approval.
