MOK-V2

MOK-V2
Highlights
  • Plug-in measuring relay, voltage threshold type, 2 contacts
  • Pick-up and drop-out thresholds adjustable with two independent potentiometers
  • Electronic circuit with no need for an auxiliary power supply
  • Solid and rugged construction
  • Excellent shock and vibration resistance
  • Wide range of sockets
Description

MOK-V2 series devices are measuring relays with adjustable hysteresis. The device measures a voltage in a monitored circuit:

- The contacts switch to 'make' status when this parameter exceeds the pick-up threshold selected by the user and expressed as a percentage of the nominal voltage

- The relay reverts to 'break' status when the measured value drops below the drop-out threshold (also selected by the user)

These models are suitable for the supervision and protection of electrical equipment used in the most demanding sectors, such as:

- Electricity generating stations

- Electrical transformer stations

- Industries using continuous production processes

- Railways, including both trackside equipment and rolling stock

The relay features two adjustable voltage thresholds:

- Pick-up Voltage

- Drop-out Voltage

The PICK-UP VOLTAGE can be set at between 60% and 120% of nominal voltage.
The DROP-OUT VOLTAGE can be set at between 70% and 98% of the pick-up voltage.

Particularly suitable for monitoring battery voltages in the rail-tram-trolley vehicles sector.
