This inverter also includes an extensive protection circuitry to shut down the inverter under certain fault conditions. Inverter Mode When the RD-E Series is fi rst powered up, it defaults to the OFF mode. The momentary Power ON/ OFF Switch (see Figure 1-1, Item 1) must be lightly pressed to turn the inverter ON. -
Page 37: Standby Mode
Figure 3-2, Power Flow - Standby Mode Battery Charging Magnum Energy’s RD-E Series is equipped with an active PFC (Power Factor Corrected) and PI (Proportional-Integral) multi-stage battery charger. The PFC feature is used to control the amount of power used to charge the batteries in order to obtain a power factor as close as possible to 1 (or unity). -

Info: If the battery voltage falls to the re-bulk voltage (24.2 VDC) or lower, the unit will begin another bulk charge. * These settings in the RD-E Series are changeable and leave the factory with default values (see Table 3-2, Inverter/Charger Default Values). These default values are adequate for most... -
Page 39: Transfer Time
The transfer from Standby mode to Inverter mode occurs in approximately 16 milliseconds. While the RD-E Series is not designed as a computer UPS system, this transfer time is usually fast enough to hold them up. However, the VAC dropout setting has an effect on the ability of the loads to transfer without resetting. -
