What are the primary applications for this 48V DC power system?
The system is designed for telecommunications, fiber optic networks, mobile communications, satellite ground stations, computer networks, and utility power distribution environments.
How does the N+1 redundancy benefit my installation?
The system supports N+1 redundancy where each individual rectifier module operates at 30A @ 48VDC. If one module requires service, the remaining modules dynamically share the load without system interruption.
What remote communication capabilities are built into the power supply?
It comes equipped with Modbus, SNMP, and RS485 interfaces, allowing remote operators to monitor input/output status, current, voltage levels, and alarm warnings in real time.
What voltage range limits apply to the AC input?
The input accepts single-phase AC current. The nominal voltage rating is 110Vac at 50Hz, with a supported operating range of 90V to 175VAC. Input derating applies under 110V parameters.
Does this power supply feature hot-swappable module replacement?
Yes. The system utilizes hot-swappable, Plug-and-Play modules, allowing modules to be inserted or removed without powering down the entire telecommunication stack.
What safety protections are integrated to safeguard connected loads?
The system features comprehensive automatic protection mechanisms, including input under/over-voltage shutdown, output over-voltage clamping, current limitation, short-circuit protection, and over-temperature safety controls.
