The LSS monitors for the presence of hazardous voltages within test chambers and safely controls the power supply and discharge of capacitor banks up to 10 kV, incorporating all the necessary emergency functions to protect personnel during testing operations. This allows existing facilities to be adapted to current safety requirements without the need for a complete replacement of the laboratory infrastructure.
One of the system's main advantages is its modular architecture, which allows the power configuration to be selected according to the needs of each test bench. It is available for power supplies ranging from 230 V single-phase 16 A to 400 V three-phase 63 A, covering power outputs of 3.5 kW, 22 kW, and 43.6 kW. This flexibility facilitates its integration into both small R&D laboratories and high-power test facilities for electric vehicles, industrial converters, or energy storage systems.
The system supports different voltage ranges for the device under test (DUT), with versions of 1.5 kV, 2.5 kV, 5 kV, and 10 kV, adapting to a wide variety of power electronics and electrification applications. Furthermore, it allows energy discharge via an internal circuit or using an external discharge system, providing greater flexibility depending on the test bench's characteristics.
In terms of safety, the Laboratory Safety Control System incorporates all the necessary functions to manage emergency situations. It continuously monitors the presence of high voltage inside the enclosure, prevents access while dangerous levels of stored energy exist, and ensures the safe discharge of capacitors before allowing the system to be opened. The maximum discharge time is 10 seconds, with a capacity to dissipate up to 10 kJ of energy.
Connectivity is another key feature of the system. The LSS has M12 connectors for interlock signals, allowing control of external safety devices, as well as a 24 VDC, 3 A output for powering auxiliary equipment such as light signaling systems or warning devices. It also includes an M12 interface for connecting an external control unit or, alternatively, using the integrated control unit.
The system also incorporates an additional power outlet, available with or without an integrated emergency stop, for powering computers, measuring instruments, or other auxiliary equipment used during testing. This feature simplifies laboratory installation and allows all test bench components to be integrated into a single, coordinated safety system.
Designed in a standard 19-inch form factor with a 4U height, the Laboratory Safety Control System is easy to integrate into existing instrument cabinets. As an option, it can incorporate an insulation monitor, providing an additional layer of oversight for high-voltage installations where detecting insulation degradation before it poses a risk to personnel or equipment is critical.
Thanks to its combination of certifiable functional safety, high-voltage monitoring, energy discharge control, and modular architecture, the Saxogy Laboratory Safety Control System is an ideal solution for power electronics testing laboratories, inverter manufacturers, energy storage systems, electric vehicle chargers, industrial converters, and R&D centers working with voltages up to 10 kV. The system significantly increases operational safety, simplifies the integration of auxiliary equipment, and allows for the adaptation of existing installations to current standards for the protection of personnel and machinery.
