This electronic digital programmable relay has been specially designed to monitor the voltage asymmetry, sequence and loss phase of a three-phase power system.

The module is designed to be mounted on Din-rail and it let to monitor all the power specifications and topologies that exist on the world.                
With its compact design (22.5mm wide casing) it can be mounted on a DIN rail.

The module can be programmed in two ways:
• Manual mode: adjust the percentage values ​​of asymmetry and time delay by potentiometers and power specifications and topologies through switches
• Programming mode: thanks to a built-in mini-USB port will be able to connect the module to a PC. With Our Devices Programmer software it is possible to program easily different percentage values ​​of asymmetry and time delay besides the power specifications and topologies that exist on the world.

Two models cover all the voltage range, with direct multivoltage supply. Versions with one and two output relays are available for both models:

Mod:

• MCP240: 200-240VAC
• MCP480: 380-480VAC

The asymmetry, correct sequence and phase loss monitoring has great applications in industry, buildings and all kinds of installations, both in loads monitoring, as in the protection of machines or small installations.

Mainly used to prevent malfunction of three phase motors in which an imbalance of the asymmetry, the loss of one phase or the inverse power can cause damage or overheating the machine.

Examples: pumps, compressors, forklifts, generators, etc.

Function 0

Factory default. Normal operating mode in which the function of asymmetry is set with the potentiometers and the type of topology of the three-phase power supply is set with the DIP switch.

Function 1

If asymmetry occurs, the alarm LED flashes until the status relay LED turn off (Lock), after which time, the alarm LED will remain lit.
Once the symmetry recovers the alarm LED will turn off and after a time (t1), the status relay LED will remain lit.
Programmable delay time relay output of 0 to 999 seconds (Lock and T1). Parameters will be set by the user using the Devices Programmer software.
In this case, one can activate or deactivate the potentiometers and the DIP switch using the Easy Control Programmer software. If activation is selected, potentiometers must be set at minimum. If this setting is changed, the settings can be configuring manually again.
If the potentiometers and DIPs are locked, the asymmetry and three-phase power specifications cannot be changed manually.
