| Datasheet | Download Datasheet |
The Macromatic VMP048D is a voltage monitor relay with DPDT output and rated 10 A at 240 V AC, 7 A at 30 V DC, driven by a 48V DC input.
It watches the supply for Over/Undervoltage, measuring true RMS.
Its upper threshold adjusts across 36 to 60V DC, and its lower across 27 to 57V DC.
The drop-out point is fixed at 95% of the pick-up setting.
It trips after 0.5 s (fixed) and picks up after 0.5 s.
It has Socketable mounting and Plug In terminals.
