Intrinsically Safe Power Supplies
The 949x-PS range of MTL intrinsically safe (IS) isolated power supplies are ideal for providing power to instrumentation in hazardous process areas. They offer a wide range of different IS output voltages, ranging from 4.8V - 17.7V, offering flexibility of options to best suit a variety of applications. The 9492-PS-PLUS is the preferred method for supplying 947x-ET/G and 946x-ET ranges of MTL IS Ethernet devices to provide direct power or IS Power over Ethernet (PoExTM), a method which allows a single cable to provide both the data connection and electrical power to devices, in turn, reducing installation costs.
- Wide range of output voltages 4.8V - 17.7V
- Wide operating temperature range of -40 ̊C to +70 ̊C for 9492-PS-PLUS and 9493-PS-xxx
- Zone 2 mountable
- DIN-rail or backplane mounting
- ATEX / IECEx certified
Additionally, the 9491-PS is FM and FMC approved for installation in Class 1 Division 2 hazardous locations with the Ex ia output certified for connection into Class 1 Division 1 Groups C, D hazardous locations. The 9493-PS-xxx provides versions for connections into both Gas Group IIB and Gas Group IIC hazardous areas.
