Sices MP250 – [Italy] Main power protection relay

Sices MP250 controller – Power protection relay is a necessary device for many power systems with or without auxiliary power, generator-using systems desperately need this protective relay for the purpose of protecting the source and both. backup power system.

Key information about Sices MP250

• TTTT Global is currently a genuine Sices generator controller representative.
• MP250 is a power protection device that continuously monitors the power parameters, to interrupt the parallel between the generator and the main power source in case a parameter is outside the set limit range.
• The digital outputs of the relay can be used to give an open command directly to a circuit breaker or to give an action command to other controllers (multiple power controllers).
• Parameter settings are managed directly by the free programming tool BOARDPRG4- Sices setting software.
• On the TTTT Global site, there is not only the Sices MP250 pdf but also the Sices GC MP250 manual.

Sices MP250 specifications 

Connection port

• 4 digital input ports.
• 6 digital output ports.
• AND/OR logic gates.
• 6 calendars and 4 timers.
• 1 USB port.

Functions that can be installed

• The secondary circuit breaker (backup circuit breaker) can be managed, in case of open failure of the primary circuit breaker (interface circuit breaker).
• A complete power protection kit is available.
• The relay features multistage protection for under voltage and over voltage, under and over frequency as well as rate of change of frequency (ROCOF).
• All protections are fully configurable, allowing the Sices MP250 TTTT to be used in different countries with different grid codes and providing crash bypass to prevent annoying tripping.
• The MP250 is fully compatible with relevant grid codes, including G59/3 and G99.
• The relay displays its operating status and alarms through the LCD graphic display and indicator lights. Front-mounted pushbuttons allow screen navigation, parameter setting, and alarm reset.
• Parameters are accessible from the front panel or by connecting to a PC using the BOARDPRG4 software.
