APS-120-550-DIN4 switched-mode power supply 55V 120W in DIN4 housing
Description
APS-120-550-DIN4 is a switching power supply in a DIN4 enclosure that can be mounted on a TH35 rail. The device provides 55V output voltage. It is most often used to power IP PoE devices, such as PoE switches in automation and monitoring systems.
The total power of the APS-120-550-DIN4 power supply is 120W, available on the DC_OUT screw connector.
Device has a redundant power supply option, which can be implemented using a second module with the same voltage, for example SWPS-4-11-DIN4 or APS-120-550-DIN4.
The power supply has a load indicator that allows you to easily determine the power consumption of the device:
| Colour | Meaning |
| White | Standby mode (no load) |
| Green | Current power consumption |
| Blue | Maximum power consumption recorded |
| Red | Power consumption exceeding ~110W (close to overload) |
Key features and functions:
- up to 120W total power from the power supply
- high module efficiency >90%
- redundant power supply (ensures continuity of power supply through a second module)
- clear indication of operating status and power consumption
- quick and easy commissioning without configuring parameters
- wide operating temperature range
Thanks to its DIN4 enclosure, the APS-120-550-DIN4 can be mounted on a TH35 rail. The standardised enclosure provides protection against mechanical damage and facilitates integration of the device into automation and monitoring systems.
The device has an IP20 protection rating. To ensure protection against weather conditions and moisture condensation, a suitable enclosure (minimum IP44) must be used.
Installation notes
- If we want to use redundant power supply for the device, it is best to supply it from separate phases of the installation so that if one phase fails, the other can remain in use.
Examples of applications
Example of using APS-120-550-DIN4 to power 6 PoE IP cameras via APT-5-50 and APT-4-11.
Example of using two APS-120-550-DIN4 modules to ensure power continuity (redundant power supply) for 6 PoE IP cameras.
Example of using SWPS-4-11-DIN4 and APT-4-11 to power 5 PoE IP cameras, with an additional APS-120-550-DIN4 power supply included to ensure continuity of power supply (redundant power supply).
