Application
The SN320 is equipped with two-stage over-current protection, overload protection, zero-sequence over-current protection, and multiple re-closing protection for each line monitored, which can automatically remove the faulty line.

Characteristics
The SN320 distribution network automation terminal adopts high-integration, high-speed, high-performance, low-power 32-bit ARM chip to form a multi-CPU structure, with fast response and strong processing capability.
Low power consumption, modular software design, complete protection function configuration
Standard 4U aluminum alloy chassis structure, front plug-in design, convenient for production, installation and maintenance, suitable for special installation requirements of distribution network
Centralized operation, it can monitor the current and voltage imbalance of the 4-segment bus and 12-circuit line at the same time, effectively remove the faulty line and reduce the power-off range.
Modular design, each board is independent of each other, can be arbitrarily matched. The module is easy to upgrade and expand.
The large-capacity non-volatile memory stores data (protection events, remote signaling SOE, daily extremum, telemetry whole-point data, etc.) with a storage capacity of not less than 30 days.
Four sets of settings for each line make it easy to switch the set of values. Support remote/local modification of settings and parameters.

Two-stage watchdog protection, dynamic self-test function to ensure reliability.
