The main feature of the primary switched module PM-IP67A200 developed by MTM Power is its design suitable for applications with protection degree IP67. It is specifically designed for the electrical supply of control, sensor and actuating systems in the field directly at the application.
The power supplies of this series allow use as a ‘plug and play’ solution directly on-site. This is possible due to the connection via special 7/8" connectors and the thermoselective vacuum encapsulation developed by MTM.
The units are available with 24 V single and dual output voltages, and are certified according to the standards UL 60 950-1 and UL 508. They have a 90 - 264 V a.c. and 100 - 300 V d.c. input range, and are designed for worldwide use under extreme environmental conditions in on-machine applications.
As an option, units with 24 V output are also available with variable current limiting designed to allow a short increase of the output power to 150%. This function, known as power boost, allows application on motors, capacitive loads, etc. which exhibit difficult startup characteristics.
The outputs of the dual-output version are galvanically separated with 500 V a.c. isolation voltage and independently regulated. The devices are according to protection degree 1 and comply with the Low Voltage Directive as well with the up-to-date EMC standards as regards CE conformity. They are constantly short circuit protected, need no ground load, and operate within a temperature range of -25°C to +60°C.
