The Hannibal PL Series is an industrial UPS platform designed to provide reliable backup power, stabilize supply quality and keep critical operations running during power outages, voltage spikes, voltage drops and fluctuations.
The range is available from 2.5 to 250 kVA in single-phase output version and from 5 to 500 kVA in three-phase output version. The platform uses SCR/IGBT technology with proven digital control and can be configured with industrial options such as custom protection devices, bypass transformer, bypass stabilizer and communication solutions.
The system is designed as an industrial UPS with commonly specified features such as dual cooling channel, input and output transformers, conformal coating of printed circuit boards and halogen-free flame-retardant internal cables.
