SVAA 400 400VAC +/-18% 0-30 s

They control a voltage range in AC voltage between the adjusted margins. When conditions are right, the relay remains activated and it deactivates when the current is shifted out of these margins.

• The models are distinguished by combinations of the following characteristics:
• Control of the own supply voltage or a secondary voltage
• Control 1, 2 or 3 set points
• Fixed or adjustable hysteresis
• Timing detection fixed or adjustable
• Display of measured values
