| Datasheet | Download Datasheet |
The Macromatic VWKP480A is a voltage monitor relay with SPDT output and rated 10 A at 240 V AC, 7 A at 30 V DC, driven by a 480V AC input.
It watches the supply for voltage band (window), measuring true RMS.
Its upper threshold adjusts across 360 to 600V AC, and its lower across 270 to 570V AC.
The drop-out point is adjustable, 75 to 95% of the over-voltage setting.
It trips after 0.1 to 10 s (adjustable), picks up after 0.5 s and re-energises 1 s after the fault clears.
It has Socketable mounting and Plug In terminals.
