If you have other power supply requirements, please feel free to contact us.
Notes: 1. The output power is rated at the condition THD+N 10%,1kHz sine wave.
2. All amplifier boards don't employ power supply reverse polarity protection. Stresses beyond the power supply range maximum ratings may cause permanent damage.
3. None typical load may cause rating power reduction.
4. Dimensions mean length and width of PCB only, excluding excessive part out of the PCB outline.
5. All parameters were tested with Rohde & Schwarz UPV audio analyzer (AES17 filter enabled) and AP AUX0025 filter. Linear Power Supply units were used for testing.
6. Sure Electronics promises all standard products life cycle more than 5 years. Sure Electronics reserves the right to update the version without notice. All the products sent to retail customers are the latest version. We will provide back-to-order service (100 Pieces MOQ needed) for our distributors in 5 years.
