Emergency power supply MD-500
Lestar OfficePower AVR protects electronic equipment against effects of voltage decay
in power grid, voltage surge in electrical systems, EMI and RFI interferences. Owing to digital voltage
Line Interactive technology-based AVR control your sensitive electronic equipment is supplied with
ceaseless and controlled power.
The series features very good hold up times as compared to comparable market offerings.
Cabling and software CD optional or free downloadable.
MD-325 and MD-500A, with their compact metal cases, remind of similar ServerPower AVR series. They have the same performance at lower power from 170W up to 250W. Hold up time from 5 up to 21 min.
Active power from 170W
Hold up time from 5 up to 21 min.
Used mainly for individual computers, both at home and office.
