Load resistor (30 to 100 VA)

The series of terminating resistors from 30 to 90 VA belongs to the category of high performance devices that are designed to work with high-power instrument transformers. The difference between these devices is the presence of two radiators that cover most of the body area. This is necessary in order to ensure efficient heat dissipation and protect internal parts from overheating.
The maximum power of loaders of the presented series reaches 100 VA, it is implemented in the single-phase model PVR1-57,7V-100VA. The limit values ​​for the load for two and three-phase devices are 30 VA per 1 phase.
The resistance of the preload resistors varies from 0.4 to 111 ohms. The minimum indicator for PCR3-5A-3x10VA and PCR2-5A-2x10VA, the maximum for PVR2-57.7V-2x30VA and PVR3-57.7V-3x30VA.
The entire range of resistors with a power of 30 to 100 VA is capable of operating in networks with a maximum current of up to 5 A, which allows you to connect instrument transformers with high performance.
