The AVS12 ® is an automatic voltage switch (SMPS < 500W) with high efficiency and safety switching.
The AVS12 kit is an automatic mains selector (110/220 V AC) designed for SMPS applications under 500 W. It consists of a low‑consumption controller and a specially optimized triac that ensure safe voltage switching and high efficiency.
The document includes block diagrams, absolute maximum ratings, thermal resistance data, electrical characteristics, reset behaviour, typical application circuits, ordering information, and mechanical dimensions, helping designers integrate the device and service technicians perform maintenance.
| Supply voltage (Vss) | -12 V to 0.5 V |
|---|---|
| Oscillator frequency | 42 kHz – 46 kHz |
| Peak off‑state voltage (Vorm) | +600 V |
| Maximum RMS on‑state current (Iams) | 12 A |
| Junction‑to‑ambient thermal resistance (Rth j‑a) | 60 °C/W |
| Recommended mounting torque | 0.8 m·N (max 1 m·N) |
The AVS12 works with 110 V or 220 V AC mains.
The triac can block up to +600 V.
A recommended torque of 0.8 m·N, with a maximum of 1 m·N, should be used.
