Power supply SATEL APS-055 5V 0.5A in-box — compact external adapter for low-voltage devices

SATEL APS-055 is a compact external power supply that delivers a regulated 5 V DC output at 0.5 A. The adapter is intended for powering low-voltage electronic devices and modules that require a stable 5 V feed. Its small form factor makes it suitable for installations with limited space, and the in-box design simplifies mounting near control panels, sensors, communication modules and other auxiliary electronics in residential or commercial setups.

Advantages

The APS-055 provides a steady 5 V output with up to 0.5 A current capacity, suitable for a wide range of low-power devices. Its compact external form reduces installation complexity and allows placement close to the powered device, minimizing cable runs. The adapter is designed for reliable everyday operation and integrates easily with control systems and peripheral modules that require a standard 5 V supply.

Suitable for

• Powering alarm control panels and security modules that accept 5 V input
• Supplying sensors and small actuators in residential and commercial installations
• Feeding communication modules, routers or interface converters with low current draw
• Providing auxiliary power to development boards and electronic modules

Key specifications

• Output voltage: 5 V DC
• Maximum output current: 0.5 A
• Form factor: compact external adapter (in-box)
• Designed for low-voltage electronic devices and modules

How to use

Connect the adapter to a compatible mains outlet using the included in-box connector or cable, then attach the 5 V output to the device's power input observing correct polarity. Verify that the device's rated voltage and current requirements do not exceed the adapter's 5 V / 0.5 A rating. Place the adapter in a ventilated area and route cables to avoid strain on connectors. For installations with multiple devices, ensure total current draw does not surpass the adapter's maximum output.

Usage recommendations

Use the APS-055 only with devices specified for a 5 V DC supply and with a maximum current draw within 0.5 A. Avoid operating the adapter in excessively humid or dusty environments and allow adequate ventilation around the unit. If a device requires inrush current or peak currents above 0.5 A, select a higher-capacity power supply to prevent voltage drop and potential device malfunction.
