Industrial Power Supply
PS-100

The PS-100/48 is a DIN-rail industrial power supply (PSU) complying with a wide range of approvals. With the robust plastic housing the PS-100/48 is one of the markets most compact PSU:s. It has been specifically designed for use with the Westermo Power over Ethernet (PoE) products and meets the requirements for both PoE and PoE Plus as the output voltage can be adjusted between 48 and 56 VDC. In some applications there might be a need to power many Powered Devices (PD):s thus the unit can deliver up to 100 Watt.

The PS-100/48 is a DIN-rail industrial power supply (PSU) complying with a wide range of approvals. With the robust plastic housing the PS-100/48 is one of the markets most compact PSU:s. It has been specifically designed for use with the Westermo Power over Ethernet (PoE) products and meets the requirements for both PoE and PoE Plus as the output voltage can be adjusted between 48 and 56 VDC. In some applications there might be a need to power many Powered Devices (PD):s thus the unit can deliver up to 100 Watt.

Mounting and connecting the unit does not require any additional tools as both the DIN-rail connector and the terminal connectors have been designed, not only, with ruggedness and the ability to sustain harsh environments, but also the made easy methodolgy using spring clamps.

Every PS-100/48 has to pass rigorous quality tests including temperature cycling at full load to guarantee quality. With very high MTBF figures the PSU is built to last.
