Key Parameters Category Parameter Specification Input Nominal Voltage 400/415 VAC, 3Ph + N Input Voltage Range Wide range, typically ±25% or more without using battery Frequency 50/60 Hz ± 10% (Auto-sensing) Output Nominal Voltage 400/415 VAC, 3Ph + N Voltage Regulation ±1% Frequency Regulation Synchronized to bypass in normal mode; stable internal oscillator in battery mode Battery Standard Battery Voltage Typically a DC bus voltage like 480 VDC (specifics depend on the battery pack used) Runtime Configurable based on external battery cabinets (EBNK series). No standard internal runtime for a unit of this power. Performance Efficiency Up to 96.5% in double conversion mode; can achieve over 99% in Eco mode Topology True Double Conversion Online Modularity Power Modules Hot-swappable. The NZMS3-4 frame typically holds multiple modules (e.g., 4 x 10 kW modules for 40kW). Communications Standard communication slots for network management cards (e.g., SNMP, Web/HTTP, Modbus, JBus, Dry Contacts). Physical Form Factor Tower / Standalone (Static) Color Typically Black
