What is the difference between the DT2000 and the DT1500?
The DT2000 focuses on high-voltage DC inputs (110/220V) for power systems; it employs masterless parallel technology and supports the parallel operation of up to 8 modules. The DT1500 covers both telecommunications and power system voltage ranges; it features a modular, hot-swappable design and supports the parallel operation of up to 4 modules.
What is the maximum number of modules that can be connected in parallel?
A single system cabinet supports the parallel operation of up to 8 modules, with a total power output reaching up to 80 kVA. For higher power requirements, multi-cabinet parallel solutions can be customized.
What is "masterless parallel technology"?
Traditional parallel systems require the designation of a “master” unit and “slave” units; if the master unit fails, the entire system may be compromised. With masterless technology, all modules operate on an equal footing—any module can function independently, and current sharing is automatically balanced during parallel operation, resulting in significantly higher reliability.
Can the dimensions of the system cabinet be customized?
Yes. The standard cabinet sizes are 42U, 45U, and 48U; however, the power distribution configuration, IP protection rating, and physical dimensions can all be customized to meet specific project requirements.
What is the transfer time?
For a single module, the transfer time from bypass mode to inverter mode is ≤8 ms. When the system cabinet is equipped with a built-in Static Transfer Switch (STS), the switching time is ≤4 ms, thereby meeting the stringent switching-time requirements of critical loads.
How is remote monitoring achieved?
The modules come standard with an RS485 interface, and the system cabinet offers an optional SNMP card; this enables integration with power system monitoring platforms, facilitating real-time remote monitoring.
