Deeply engaged in the field of power switching, we have created an efficient, precise and safe core for power supply assurance, suitable for industrial, commercial and special power scenarios, and building a defense line for power continuity and reliability. It can achieve dual power switching and uninterrupted power supply. It is widely applied in scenarios with high power supply requirements such as telecommunications, rail transit, emergency fire protection, and smart buildings:
History record storage: Supports the storage of 526 records, with comprehensive and complete data retention.
System power supply mode: Compatible with 4 power supply modes including dual mains power, mains power + generator power, and dual generator power.
Precise electrical parameter monitoring: Collecting two-phase three-wire voltages, frequencies, phases, as well as load power, factor, and current values.
Comprehensive protection alarm: Includes electrical protection such as overvoltage, undervoltage, and phase loss. Supports S1/S2 overcurrent alarms and NEL load trip. Offers flexible control functions: Supports automatic/manual switching, parameter encryption and programming, and includes manual test operation and switch reclosing functions.
Intelligent unit control: Multi-period timing start and stop, capable of controlling two units to operate in a cycle, as the primary unit, or in a balanced manner.
Wide voltage range compatibility: Can withstand 80V of direct current for a short period, and up to 625V for alternating current. Supports multiple AC systems, with two separate N lines.
Communication compatibility expansion: RS485 (ModBus) remote four functions, compatible with various types of switches
Three types of automatic switching modes
Primary and backup operation: The mains power is the primary power source, and the generator is the backup power source. The primary power source supplies power continuously when it is normal, and automatically switches to the backup power source in case of a failure.
Cyclic operation: Two generators supply power alternately according to the set duration. For example, A operates for 360 minutes and then switches to B, and B operates for 480 minutes before returning to A, and this cycle repeats.
Balanced operation: Based on the cumulative power supply duration of the two generators, the side with shorter usage time is automatically selected as the primary power source, achieving balanced wear on the two devices and facilitating unified maintenance.
