Redundant power supplies

China (mainland) – The EAM series from Guangdong East Power Co. Ltd is a true online double conversion network power supply system that features a modular and user-upgradeable design, allowing users to expand or add power density as required. It consists of parallel hot-plugged 2Ux19mmx455mm UPS, 6Ux19mmx455mm bypass and 4Ux19mmx455mm display modules, and is housed in a 1,800x600x800mm standard cabinet. It features a touchscreen display, RS-232/422/485 interfaces, a network card and a sealed lead-acid maintenance-free battery.

The unit has 384V DC nominal voltage, and supports three-phase four-wire input/output (rated at 380V AC) or single-phase two-wire input/output (rated at 220V AC) voltages. It has 277V to 468V AC linear voltage or 160V to 270V AC phase voltage input at 50Hz +/-5Hz or 60Hz +/-5Hz, 380V AC +/-1 percent or 220V AC +/-1 percent output voltage at 50Hz +/-0.01Hz or 60 Hz +/-0.01Hz, and standard sinusoidal output waveform. It withstands up to 110 percent overload for 10min, 120 percent for 1min with voltage protection and up to 150 percent linear load for 200ms. It has less than 40ms recovery time from response. It has more than 96 percent efficiency at 3:1 peak value, 10 percent dynamic response, 2 percent (linear load) and 5 percent (non-linear load) THD and 3 percent imbalance load. It generates less than 50dB noise level when operating at 100 percent load.

The series is available in 10kVA (EAM-10), 20kVA (EAM-20), 30kVA (EAM-30), 40kVA (EAM-40), 50kVA (EAM-50), 60kVA (EAM-60), 70kVA (EAM-70), 80kVA (EAM-80), 90kVA (EAM-90) and 100KVA (EAM-100) models. Each model meets EN 50091-1 and EMC EN 50091-2 Liv.A standards.

Minimum order is 500 units and delivery takes 25 days.
