IRS2092S dual symmetrical power supply for audio amplifiers: ±48V DC, 500W, 230V

A dual, symmetrical power supply for audio amplifiers, e.g. for the IRS2092S and other circuits, with dual output voltages (positive and negative) of ±48V and a maximum power output of 500W.

This power supply has a triple output: +48V, GND and -48V; the input voltage is the standard 230V AC, and it is designed for audio amplifiers. The maximum power output without active cooling is approximately 60W at room temperature; current draw exceeding this value requires the use of active cooling in the form of a fan. The product is designed for installation in a suitable enclosure.

Technical specifications:

• Input voltage: 230V AC 50Hz + earth
• Output voltage: +48 V GND -48 V DC
• Auxiliary output voltage (for fan): ±15V DC (300mA)
• Maximum output power: 500W
• Dimensions: 113x74x56mm
• Net weight: 260g
• Protections: against overheating; switches off automatically when the temperature exceeds approx. 70°C

Package contents:

• power supply

Warning: Do not touch the power supply with bare hands once it is connected to the mains!! After disconnecting the mains supply, high voltage remains present for several minutes due to charged capacitors!! Installation is for professional and experienced electronics engineers only.

Note 2: Do not load only one line, e.g. only +48V or only -48V; the load should be evenly distributed across both power supply lines.
