## Summary description

ATTE APS-90-480-S1 is a switched-mode power supply (SMPS) delivering 48 V DC at 2 A with a maximum output power of 90 W. Designed for stable low-voltage DC powering of telecommunications, networking equipment, LED systems and industrial control devices. Features include regulated output, short-circuit and overload protection suitable for continuous operation.

## Long description

The ATTE APS-90-480-S1 SMPS provides a regulated 48 V DC output at up to 2 A, delivering a maximum of 90 W for continuous low-voltage applications. This compact switching power supply is intended for stable powering of telecommunications gear, network devices, LED lighting modules and various industrial control systems that require a steady 48 V source with built-in protection features.
Advantages
The unit features an efficient switched-mode design that minimises heat generation and improves energy conversion compared with linear supplies. It offers regulated output voltage for stable performance under varying loads, plus integrated short-circuit and overload protection to reduce the risk of damage to connected equipment. Its compact form factor and standard mounting options allow straightforward integration into cabinets and enclosures.
Suitable for
Powering telecommunications and networking equipment that require 48 V DC supply.
Driving LED lighting systems and LED drivers designed for 48 V input.
Supplying industrial control devices, PLCs and sensors operating at 48 V.
Backup or auxiliary power for low-voltage electronic modules in cabinets and racks.
When it may not be suitable
This SMPS is not suitable for applications that need voltages other than 48 V or currents higher than 2 A. It is not designed for use as a direct replacement where galvanic isolation requirements, medical certification or highly specialised environmental ratings (for example, extreme temperature or ingress protection) are strictly required.
Key specifications
Output voltage: 48 V DC
Maximum output current: 2 A
Maximum output power: 90 W
Regulation: regulated DC output for load stability
Protections: short-circuit and overload protection
Intended operation: continuous duty
How to use
Install the power supply following local electrical codes and the enclosure or cabinet manufacturer’s instructions. Connect the AC input to an appropriate mains source with correct fusing and ensure the output wiring is sized for the 2 A maximum current. Verify polarity before connecting loads. Allow for adequate ventilation around the unit and avoid obstructing any cooling pathways. If used with sensitive electronics, confirm the receiving device accepts a 48 V regulated supply and that inrush currents do not exceed the supply’s protection limits.
What to consider before purchase
Confirm that the required load voltage is 48 V DC and that total current draw does not exceed 2 A.
Check compatibility with the target device regarding grounding and any isolation needs.
Verify required protection ratings or certifications for your installation environment.
Ensure physical dimensions and mounting method fit your cabinet or enclosure.
Usage recommendations
For reliable operation, place the power supply in a ventilated area, use correct cable cross-sections for the output run, and incorporate appropriate fusing on the AC input. Periodically inspect connections for corrosion or loosening in installations subject to vibration or temperature changes.
