P91g Li 1.5-3kVA



High performance online UPS with up to 10 year battery lifespan


Lithium-ion battery technology provides up to 10 years of battery life and reduced cost of ownership.

When compared to typical lead acid batteries, lithium-ion batteries provide more than twice the life, higher temperature tolerance, longer runtime, and faster recharge. Online double conversion technology makes P91g Li UPS ideal for protection of network, server, edge and distributed IT applications.

P91g Li UPS models include redundant Battery Management Systems (BMS) insuring cell voltage balancing, current sharing and protection for over-charge and over-discharge
