PS-72W

Soft dB PS-72W - 72W power supply for SMS-NET controllers

The Soft dB PS-72W is a high-efficiency 72W power supply designed to power SMS-NET controllers in professional sound masking systems. It supports a wide input voltage range (100–240V AC) and complies with international safety and energy efficiency standards, including DoE Level VI.

Delivering +24V DC at up to 3A, the PS-72W ensures stable power with excellent load regulation and protection against overvoltage and overcurrent. Its fire-retardant enclosure (rated 94V-0) ensures safe operation, while low standby power consumption (0.21W) and high efficiency (>88%) make it ideal for energy-conscious AV installations.

Equipped with a standard IEC C13 input and available with international plug options (NEMA 5-15P, CEE 7/7, BS-1363, AS 3112), the PS-72W is globally compatible and certified by UL, CE, FCC, TUV, CB, and more.
