On Line High Frequency UPS (EA900)
The EA900 series UPS is an intelligent high-frequency on-line UPS, with capacity ranges from 1KVA to 10KVA and suitable for equipment for data processing centers, host computer systems, integral computer networks, ISP service providers and telecom. The unit is controlled by a CPU and equipped with monitoring and protection functions.Our EA900 series use 50kHz high-frequency technology, allowing for smaller, lightweight design.The units have a pure sine wave output allowing the UPS to handle many kinds of load.With advanced RS232 and USB port monitoring software and a front-mounted LCD screen, the customer has direct access to the status of the UPS and can ensure the safety of the connected equipment.CPU-controlledCompletely sine wave output, using advanced IGBT technologyWide power compatibility rangeAutomatic detection and selection of output frequencyHigh current and high frequency processing capabilityFully isolated fast rechargeDC battery start possibleLong-distance network monitoring possibleCPUIt contains a 32-bit data-bus microprocessor with robust processing power capable of detecting and controlling all changes to UPS quickly and accurately, ensuring high product reliability.Using our innovated control software controlling the internal CPU, you can protect and monitor the UPS accurately.RS232 and USB communication portUsing the RS232 or USB communication port to access the pre-installed monitoring software, the UPS power status can be monitored directly. The network management is simplified and the reliability of the computer system is enhanced.Integral control panelThe control panel displays the operation status, loading status and the power supply status of the UPS, which can give instant knowledge of the status of the UPS.Startup self-diagnostic functionAt startup our UPS runs a self-diagnostic of the installed components (inverters and batteries) and loads. It will enable the early detection of any problem to avoid any malfunction.Cold start-up functionThe unique DC startup enables the direct start-up of UPS upon power failure of the power supplier, which helps keep the emergency backup function of our UPS available.
