Prostar ET30K 3 phase double conversion long backup power supply ups 30kva is a high-performance digital UPS using the DSP control technology. The 3 phase 30kva ups is connected between the mains and critical loads to supply high-quality power to the loads.
The 3-Phase 380/400/415V 20kVA 20kW On-Line Double-Conversion UPS with IGBT technology provides battery backup and AC power protection against power disturbances. It’s recommended for critical IT or corporate infrastructure, telecom, LAN/WAN, security and emergency, financial and light industrial applications.
Prostar ET-PLUS series design allows continuous operation at any supported voltage at either 50 or 60 Hz. Zero transfer time to battery mode ensures no disruption to the attached loads. Automatic and Manual Bypass keeps connected equipment powered even during overloads and UPS maintenance.
ET30K 3 phase double conversion long backup power supply ups 30kva seamlessly links to your electrical network using state of the art electrical performances like very wide input voltage range, high overload and short circuit capacity, and integrated back feed protection, providing excellent power quality.
This IGBT UPS benefits from highly efficient transformer-free double-conversion technology that delivers operating cost savings. It achieves 93% efficiency in double-conversion mode and up to 98% in ECO mode, reducing your power and cooling costs.
