Intrinsically Safe Power Supplies

Brand: MTL Instruments
Add Product to My Catalog

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.
Features
  • 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

MTL 9491-PS
MTL 9491-PS
The 9491-PS Power Supply is the preferred method for supplying the 9460-ET range of intrinsically safe Ethernet modules and is based on an isolating power supply. It takes a 24V DC safe area / Zone 2 / Division 2 supply and produces an intrinsically safe, 12V DC nominal output capable of powering the Ethernet modules mounted in a Zone 1/ Division 1 hazardous area. The 9491-PS may be mounted in a safe area, Zone 2 or Division 2 hazardous area.
  • Isolated Power Supply
  • Zone 2 & Division 2 Mountable
  • DIN-rail or Backplane Mounting
  • ATEX / IECEx Certified
  • FM / FMC Approved
  • 200mA at 10.9V DC - Ex ia IIB Groups C, D Output
  • 400mA at 11.8V DC - Ex ib IIB Output
  • Power Over Ethernet Option
  • Multiple Outputs Achieved by Ganging 9491-PS Modules Using 24V DC Power Distribution Backplane
MTL 9491-PS-PLUS
MTL 9491-PS-PLUS
The MTL 9491-PS-PLUS takes a 24V DC safe area / Zone 2 supply and produces an intrinsically safe, 12V DC nominal output capable of powering devices mounted in a Zone 0 (ia) or Zone 1 (ib) hazardous area. The 9491-PS-PLUS may be mounted in a safe area or Zone 2 hazardous area.
  • Isolated Power Supply
  • Zone 2 Mountable
  • DIN-rail or Backplane Mounting
