IP67 power supplies

6 July 2011 Power Electronics / Power Management

The AC/DC power modules series PM-IP67A200 with 24 V single- and dual-output voltages from MTM Power have been UL/cUL certified according to the standards UL 60 950-1 and UL 508.

The primary switched modules are suitable for applications with protection degree IP67 and are especially designed for the electrical supply of control, sensor and actuating systems in the field directly at the application. The compact supplies with wide AC (90-264 V) and DC (100-300 V) input ranges are designed for worldwide use under extreme environmental conditions for different tasks in all on-machine applications.

As an option, units with 24 V output are also available with variable current limiting designed to allow a short time increase of the output power by 50%. This function finds application on motors, capacitive loads, etc. which exhibit difficult startup characteristics. The outputs of the dual-output version are galvanically separated with 3,3 kV a.c. isolation voltage and independently regulated. The PM-IP67A200 is constantly short circuit protected, needs no ground load and operates across a temperature range of -25°C to +75°C.
