MDH9-DC
- Meets both Class I (10/350us waveform) and Class II (8/20s waveform) SPD tests
- Based on zinc oxide technology
- Using 34S-H high-performance MOV, the maximum will be up to 10/350μs 9kA
- No power frequency continuous flow
- The operating environment temperature is -40°C~+80°C
- Remote signaling function is optional.
- When product fails, the green window turns to red and remote signaling provides remote alarm function
