12VDC 26,7A 320,4W output, 100-240VAC 4-2A input Mean Well RSP-320-12 switching mode power supply with PFC, screw terminals *new*

Switching-mode power supply (also known as switched-mode power supply, SMPS) is very commonly used type of power supply. SMPS is perfectly suited for various situations where even a bit more power is needed, but the power supply weight must be minimal. Switching-mode power supplies usually have without exception a wide operating voltage (typically 100...240VAC) and they accept 50Hz and 60Hz electricity.

This power supply manufactured by Mean Well is quite a small package. Tight industrial grade aluminium housing with active fan cooling makes sure, that temperatures does not rise too much even under heavy loads. With smaller loads power supply is silent, since the fan just starts up when internal electronics reach 40°C temperature. Power supply has overload protection, short circuit protection, over temperature protection, three screw terminals for plus and other three for minus (eases up connection if there is multiple wires to feed). Output voltage presence is signaled by green LED. If you require voltage finetuning, then that can be done with the help of a small trimmer pot and it can be adjusted between 10...13.2VDC. Power supply has also built-in active (PFC) power factor correction circuitry.

The chassis has a decent amount of rigging points from the point of mounting:

• 2x M4x0.7 L=5mm on both side
• 4x M4x0.7 L=3mm on the bottom

Switched-mode power supply advantages:

• High efficiency (89% in this power supply)
• Low loss of power
• Small size and weight
• Small standby power consumption

Application examples:

• LED lighting power supply
• Power supply for industrial needs
• HAM-radio equipment power supply
• Point of sales appliances power supply
• IT appliances power supply (modem, LAN switch, printer, scanner)
• Power supply for your own do it yourself projects
