1.Production Introduction

JLF-11 and RLF-31 series 1kVA to 30kVA is a full-digitized with European MCU controlled single phase input/single phase output or 3 phase input/single phase output online UPS. It provides reliable, stable, and constant AC power for computer equipment, telecommunication devices, precision equipment instrument, and network termination equipment (NTE). UPS systems protects all these devices from losing data or information due to power outage, interruption or disruption to truly and comprehensively solve power issues, such as power outage, power surge, voltage sags, temporary over-voltage, temporary under voltage, frequency offset,power disturbances, switching transients, and harmonic wave distortion.
