Request Information »

Static transfer switch available in 3 sizes (32A, 63A, and 120A) and designed to protect 1-phase loads with different power ratings.

Features a manual bypass that enables even non-technical staff to easily switch between 2 independent power sources in the event of a supply failure.

 

Complete Diagnostics

Master Multi Switch features a 32-character LCD display and a control panel with multi-functional keys. This enables you to monitor readings and switch operating statuses quickly and intuitively.

Incorporates 3 programmable dry contacts, RS232 serial connection port, and a communications slot to allow for further LAN connection as well as remote monitoring and control.

 

Load Protection

In the event of a fault, MMS guarantees switching time between the 2 power sources of less than a quarter of a cycle (< 4 msec for synchronised inputs; < 10 msec for non-synchronised). This is the case for both automatic and manually-triggered switches.

Microprocessor control and the use of thyristor static switches ensure continuous monitoring of the power supply sources and reduced switching times between the two sources in the event of a fault.
