Delta Electronics SSW 230 V - 20 kVA Product Specifications

SSW 230 V – 20 kVA → Description: The static switch product line is a micro-controller driven state-of-the-art switch between the AC mains and the inverter to provide uninterruptible AC power. After an extremely quick detection of a mains fault, the static switch transfers the load almost without cut off to the redundant AC line. A communication and synchronization bus is responsible for the system performance and the Delta inverters are synchronized to the public AC mains. Modular UPS configurations in ON LINE or OFF LINE mode can be realized in combination with Delta inverters and DC power systems with battery backup. Features • Two static switch models 6 kVA and 20 kVA • 230 Vrms / 50 Hz single phase • ON LINE or OFF LINE mode selection • High performance AC line quality monitoring • Quick detection of AC faults • Configurable switching criteria • Load transfer of up to 6 kVA or 20 kVA • Synchronization of the Delta inverter group • Convection cooled • Compact and light • Power connectors on the rear Specification General Product name SSW 230 V – 6 kVA SSW 230 V – 20 kVA Safety EN 60 950, class I EMI, radiated compliant with EN 55 022, class B EN 300 386-2 Cooling Convection cooled Public AC Input Voltage range 184 ... 276 Vrms Frequency range 45 - 55 Hz EMI, conducted compliant with EN 55022, class B Inverter AC Input Voltage range 230 Vrms ± 1% Frequency 50 Hz EMI, conducted compliant with EN 55022, class B AC Output Voltage, nominal 230 Vrms Frequency, nominal 50 Hz Maximum power 6 kVA / 20 kVA cosφ, range 0 .. 1 ind. and cap.
