Inverter 20-33VDC

The Espey MS-28-120AC-2500 inverter is based on field proven MS- 28-120AC-400-B 400VA inverter that is part of Espey’s Modular AC or “MAC” family of inverters. The technology is based on the Espey 500W MAC Stick inverter family. This unit produces single phase pure sine wave power that is driven by a DSP chipset and firmware common to other MAC Inverters. The sealed mechanical design provides protection for the electronic components against dust, water spray and external environmental factors. The tunnel heat-sink feature allows for operation with high component reliability in high temperature environments. An integrated IP-67 rated cooling fan runs only when necessary.
