Product "EAST EA901PSRT Online UPS 1000VA (900W), 19" rack 2U, LCD, RS232"
EAST EA901PSRT is a 1000 VA / 900 W double-conversion (online) UPS for a 19-inch rack — the smallest model of the series. The output is rebuilt continuously, so the load always sees a clean sine wave and the transfer time is 0 ms.
Key Advantages and Features:
- True double conversion: The output is rebuilt continuously, so mains sags and noise never reach the load. Transfer from mains to battery takes 0 ms.
- Wide input range: Works from 110–300 V and 40–70 Hz — the battery is only used when the mains is genuinely gone.
- Easy on the mains: Active power factor correction keeps the input power factor up to 0.99.
- ECO mode: Up to 95 % efficiency in ECO mode.
- Hot-swap batteries and ABM: Batteries are hot-swappable; ABM charging restores 90 % of capacity in three hours.
- LCD menu and RS232: Output voltage, EOD, auto-start and bypass mode are set from the LCD. RS232 is standard; USB, RS485, dry contacts and an SNMP card are optional.
- Rack or tower: The 2U housing fits a 19-inch rack, or stands upright on the feet.
