D11A DC/AC inverter 4000VA with Maintenance bypass & Cabinet (Expandable to 5000VA)


SANUPS D11A Converts 48V DC input to Pure Sine Wave 120V AC Output.

Computers, IT, and communication devices that require AC power are often times forced to rely on DC power supply systems for more effective energy use.

D11A DC-AC parallel redundant inverters are designed to achieve high-reliability, high efficiency, small form factor, and easy maintenance.

*Rack Support Rails are sold separately.

Product description

D11A switches to an AC input bypass circuit keeping the connected load up and running without fail even if the main DC input power source fails. A redundant setup will bring unprecedented reliability to mission critical equipment.


Parallel operation cabinets come with 3, 5, or 6 connections. Installing an inverter in a parallel cabinet results in following redundant operation (3 = 2kVA, 5 = 4kVA, and 6 = 5kVA). Bypass power supply function is available for both parallel and stand alone inverters. D11A can supply AC power even if direct current has completely failed.


SANUPS D11A uses a simple plug-in connection. Cable-free installation and maintenance can be performed from the front of the unit actualizing hustle-free ease of use.


There are 3 types (3kVA, 5kVA, or 6kVA) of cabinets for D11A. Each type allows your capability to expand as your business grows. Also, installing an inverter on a cabinet allows parallel redundant operation to your mission critical equipment.
