Features
Parameters
Specification
Application

Dual input: standard installation of one or two independent power supplies is allowed

Automatic internal bypass: built in 100% rated bypass static switch, which allows the load to be transferred from the mains supply to prevent power failure in case of serious overload

Parallel 1 + 1 redundancy: connected equipment can be powered by two parallel UPS to increase system redundancy

Strong and durable design: the internal circuit board is protected by special coating, equipped with IP21 protection grade and dust filter net, which can better resist harsh environment

Built in transformer: it can be configured as bypass transformer or output transformer on site to realize complete electrical isolation and strengthen load protection

Powerful charger: an overall solution that can meet most backup time requirements, and can be applied to super capacitor or lithium battery

Industrial Design: support 100% non-linear / unbalanced load and provide genset compatibility

Manual maintenance bypass: easy to operate maintenance bypass, which allows complete isolation of all parts of the system, and supports maintenance operation at the same time of continuous power supply

Front and back maintenance: power device maintenance only needs to open the front and rear doors, and PCB board is installed on the top of the equipment. Meet the needs of parallel cabinets on both sides.

Input power factor correction: cable, breaker and generator do not need to be too large

Intelligent battery maintenance calendar: self defined maintenance calendar, full-automatic charge and discharge management on time, to prevent the battery from aging in advance, and extend the battery life

Multiple operation modes: online, online interactive (ECO) and backup optional functions are provided, and operation modes are selected according to the load demand to save energy and reduce consumption.

Easy to install: equipped with casters for easy movement, all cable connectors are easy to identify, saving installation time

Power on Wizard: step-by-step guidance and intuitive menu display for easy setup and system navigation

Flexible communication options: equipped with dry node, MODBUS and SNMP network card, supporting remote and local monitoring and management

User friendly graphic interface: easy to view LCD display, supporting analog diagram, sound alarm and multi language display, easy to operate
