What is the difference between the DT1500 and the DT2000?
The DT1500 utilizes a 1/2 19-inch module design that supports hot-swapping and allows for parallel operation of up to four units; it offers two input voltage options: 48V and 220V. The DT2000 is a full-width module that supports masterless parallel operation of up to eight units, with input voltage options of 110V and 220V; it is suitable for higher-power applications.
Since the modules support hot-swapping, is it necessary to configure any parameters?
No. The modules are plug-and-play; the system automatically detects them and performs current sharing without requiring any parameter configuration.
What is the function of the STS built into the system cabinet?
The built-in STS enables automatic switching between dual AC inputs, with a switching time of ≤4ms, thereby further enhancing power supply reliability.
How is remote monitoring achieved?
The modules come standard with an RS485 interface, and the system cabinet offers an optional SNMP card, allowing for integration into a dynamic environment monitoring system.
Does altitude affect the output?
At altitudes between 1,500m and 3,000m, the output power is derated by 1% for every 100-meter increase in elevation; please select the appropriate model based on your actual altitude.
Which battery types are supported?
The system supports lithium-ion, lead-acid, gel, and nickel-cadmium batteries; the battery parameters are fully configurable.
