What is the difference between the Power-type and Communication-type DT1000 models?
The primary difference lies in the input voltage. The Power-type model supports high-voltage DC inputs (110V/220V), making it suitable for use with DC power distribution panels in power systems; the Communication-type model supports low-voltage DC inputs (24V/48V), making it suitable for use with battery banks in communication base stations.
Can other input voltages be supported?
The standard product models are designed for 110 Vdc and 220 Vdc inputs; for other voltage levels, please contact us regarding custom solutions.
Does it support parallel operation?
No, it does not. The DT1000 series features a standalone design; if parallel redundancy functionality is required, we recommend selecting the DT2000 parallel series instead.
How is remote monitoring achieved?
The product comes standard with RS232 and RS485 interfaces, and an optional SNMP card is available to enable integration with power system monitoring platforms.
What is the transfer time?
The transfer time from bypass mode to inverter mode is ≤5 ms, meeting the switching time requirements of power systems.
Is it suitable for use in high-altitude regions?
The standard operating altitude is ≤2000 m. For higher altitudes, derating is required; please contact us for a specific solution tailored to your needs.
