LEGRAND UPS WHAD HE ONLINE 1000VA 1000W [LG-310164]

The Legrand UPS model Whad HE 1000 is an uninterruptible power supply with high frequency PWM technology, On Line Double Conversion type, through neutral, Nominal Power 1,000 VA – 1000 W, equipped with valve-regulated hermetic accumulator batteries , contained inside the UPS in a special compartment or in one or more external cabinets, sized to guarantee a minimum autonomy of 10 minutes at 80% of the load. The UPS rectifier consists of a control and regulation circuit (PFC), which in addition to the normal rectifier functions: automatically corrects the power factor of the load to bring it back to a value >0.99 already with an applied output load equal to 20% of the nominal load power the inverter without request energy from the batteries even in the presence of very low mains voltage (operation with mains power for VIN values ​​≅ 110 Vac at 50% of the nominal load) ensure total harmonic distortion of the THDIin input current

The bypass circuit is designed and built in accordance with what is described below:

Electromechanical switch Command and control logic managed by a microprocessor which provides for: automatically transferring the load directly to the primary network without interruption of the power supply, in the event of overload, overtemperature, direct voltage outside tolerances and inverter anomaly conditions; automatically re-transfer the load from the primary network to the inverter line, without power interruption, when normal load conditions are restored; if the primary network and the inverter are not synchronized the bypass must be disabled. In order to protect the batteries from damage resulting from deep discharges, the minimum battery voltage threshold allowed varies automatically according to the applied load (default setting), while still giving the user the possibility of selecting management with fixed voltage thresholds. Diagnostic and shutdown software (UPS Communicator), if appropriately installed on a PC connected to the UPS, allows you to access all operating data, make adjustments and settings of special functions and control the shutdown of Windows and Linux operating systems. An optional software (UPS SuperviSor) allows multiserver hierarchical shotdown and remote UPS management for any operating system in a heterogeneous network (Windows, Novell, Linux and the most popular Unixes). Whad is managed by a microprocessor and is able to display alarms and operating modes via a LED control panel as described below:
