The Legrand Whad HE 4000 UPS model is an uninterruptible power supply with high-frequency PWM technology, On-Line Double Conversion type, passing neutral, nominal power 4,000 VA – 4,000 W, equipped with valve-regulated hermetic accumulator batteries, contained inside the UPS in a special compartment, sized to guarantee a minimum autonomy of 11 minutes at 80% load. The UPS rectifier consists of a control and regulation circuit (PFC), which, in addition to the normal rectifier functions, provides:
- automatically correct the load power factor to bring it back to a value >0.99 even with an applied output load equal to 20% of the nominal load
- ensure a total harmonic distortion of the input current THDIin < 3% without the addition of filters or additional components
The bypass circuit is designed and manufactured in accordance with
as described below:
? Electromechanical switch
? Command and control logic managed by microprocessor that
provides for:
- automatically transfer the load directly to the primary network without interrupting the power supply, in the event of overload, overtemperature, DC voltage outside the tolerances and inverter anomalies;
• automatically transfer the load from the primary network to the line
inverter, without interruption of power supply, upon restoration of the
normal load conditions;
- if the primary grid and the inverter are not synchronized the bypass
- will need to be disabled.
In order to protect the batteries from damage caused by deep discharges, the minimum allowed battery voltage threshold varies automatically according to the applied load (default setting), while still allowing the user the possibility to select a
Fixed voltage threshold management. Diagnostic and shutdown software (UPS management software), if properly installed on a PC connected to the UPS, allows access to all operating data, adjustments and settings for special functions, and control of the shutdown of Windows and Linux operating systems. Optional software (UPS SuperviSor) allows hierarchical multi-server shutdown and remote UPS management for
any operating system in a heterogeneous network (Windows, Novell, Linux and the most popular Unix).
