The Laboratory of JSC "SU-EnergoGrupp" has tested a static load switch СПН3-380/63 ГРЛЦ 565516.001

The Laboratory of JSC "SU-EnergoGrupp" has tested a static load switch СПН3-380/63 ГРЛЦ 565516.001 to replace the static switch STS-400-63-3-RM manufactured by General Electric. It was previously operated under severe conditions in the systems of uninterruptible power supply (СГЭП). The test results have shown that the switch СПН3-380/63 satisfies all the requirements for operation in underground and has advantages over the static load switch STS-400-63-3-RM manufactured by General Electric:

• Flexible options for adaptation to different operating conditions;
• Digital control system;
• Maintenance bypass with possibility to select automatically the working source (30ms switching time);
• Not sensitive to noise (less than 1ms) in the network, thus avoiding unnecessary switching;
• Internet port for remote monitoring;
• Touch panel for control and management of the SLS;
• Real-time clock for a chronological event log in the electronic journal on the operator panel.

Up to date, the certificate of conformity № RU C-RU.MH04.B.00145 of the static load switch СПН3-380/63 is received, which is produced according to technical specifications of ГРЛЦ 565516.001 ТУ.

СПН3-380/63 will increase the reliability СГЭП (the systems of uninterruptible power supply) operated under real underground conditions.
