RS PRO Switching Power Supply, 48V dc, 3.3A, 158W, 1 Output, 170 → 264 V ac, 85 → 132 V ac Input Voltage

This RS PRO 158 W embedded switch-mode power supply (SMPS) offers a reliable way to convert an AC power supply into 48 V DC output for charging compatible devices. This type of power supply switches a capacitor on and off at high frequency to efficiently convert the AC input to the required DC output voltage.
The unit's no-load power consumption of less than 0.5 W reduces energy wastage when on standby, while its metal case prevents overheating by encouraging airflow. It also features overload and short-circuit protection to prevent damage to components. The chassis mounting design and compact dimensions make the product easy to mount onto base plates or backplates.
This type of device is commonly used in amplifiers, TVs and computers. It's Restriction of Hazardous Substances (RoHS) approved too, so you can be certain it contains only minimal levels of harmful materials.
