General
The EA-DSPMP series provides an uninterruptible power source for critical equipment to cover failures in the mains supply.
The units can protect connected systems against power failure, undervoltage, overvoltage, frequency variance and harmonic distortion.
Functional principle
The units work with the double conversion principle in the voltage and frequency independent category (VFI).
Input power passes directly through a converter which feeds the battery.
Output is provided exclusively from an inverter which is supplied either from the converter using mains power, or from the battery in case of mains failure.
Security of supply is increased by provision of bypass switching, parallel to the converter and inverter
