The SDM series offers the same protection functions as the SD range and is also designed for international use with two voltage levels:
- Stabilise voltage fluctuations from 88 to 121 VAC or 176 to 242 VAC to within ±1.5 %
- Functional area: 77 until briefly 132 VAC or 154 until briefly 264 VAC
- Attenuates asymmetrical interference voltage spikes from 40 to 60 dB
- Short term voltage dip compensation up to 10 ms
- Input and Output configurable for 110 or 220 VAC
