SJDA Power Distribution Automation Device
Our SJDA power distribution automation device comes with many measuring devices for parameters like voltage, current and so on. Besides, it can also calculate the active power, reactive power, power factor, electricity energy, harmonic wave, frequency, and so on.
The analog value input and off/on value input and output can be flexibly settled.
The busbar is embedded in the chip, so the anti disturbance performance is greatly improved.
The hardware of our SJDA power distribution automation device is designed concisely. The composite board, surface mounting technology, and industrial/military grade chips are adopted. All the chips and other components are on a printed board. The size is small and the toughness is great. So the product can be used in a large temperature range, while the power consumption is quite small.
SJDA 2000 is the solution for uninterrupted power distribution, the monitoring and analysis functions are integrated together.
