La Marche releases the new A-Series UPS System (AUPS) which is an Uninterruptible Power Supply system designed to utilize separate rectifier and inverter components allowing for simplicity in sizing the system and flexibility in configuring each component as required. The Static Switch in this UPS Series is a fast transfer switch that can be configured to have either the Inverter or the Alternate
Source as the primary source. AUPS systems are also equipped with a rotary Make-Before-Break Manual Bypass Switch.
The pure sine wave Inverter provides reliability through transistor switching and a ferroresonant transformer which has inherent voltage regulation, output filtering and overload protection.
The Rectifier (Charger) section uses controlled ferroresonant technology, with separate adjustable voltage settings for float and equalize. It provides high efficiency, high power factor, short circuit protection, and an integral alarm package.
AUPS systems are available in many AC voltage ratings and with DC bus voltages up to 125Vdc. Along with separate Form-C Alarm Contacts for each of the rectifier and inverter sections, AUPS systems also provide remote monitoring capabilities via DNP3 and Modbus protocols.
