UNINTERRUPTIBLE POWER SUPPLY
UPS systems
Available with many different configurations and technical solutions, the UPS’ are covering a power range from 1kVA up to 200kVA. Furthermore, Elettro is specialised in low power three phase UPS (1÷8kVA), with very long back-up time up to, and more, 24 hours and with input and output customized voltages. For an easier erection & installation, the battery can be supplied complete with steel type rack with acid proof protection coating or mounting cabinet, even for NiCd battery.
CUSTOMIZATION
Our A.C. systems can be extremely customized, even mechanically. The cabinets can be made on request with specific dimension, colour, door opening and protection degree IP. Big systems can be divided in more sections for an easier transportation & installation. The internal components, material & circuit breakers may be chosen respecting a Customer’s vendor list and much more.
GENERAL TECHNICAL CHARACTERISTICS
Input: Single phase 110-230Vac 50÷60Hz Three phase 200-400-415 Vac 50÷60 Hz
Battery Charger: intended for battery recharging according to the relevant specifications, either lead, or sealed lead, or nickel-cadmium battery, it can be provided with fully- controlled (6 pulse) or dodeca-phase (12 pulse) rectifier bridge. It can be also included the A.C. input isolation transformer.
Inverter: it is made with PWM technology using IGBT power modules and provided of output isolation transformer. The electronic control card is microprocessor based.
Static Switch: it is made with high power Thyristor (SCR) with very fast switching between inverter-mains, and vice versa, in zero time. The electronic control card is microprocessor based.
Manual By-Pass: always available with static switch, it is very useful for a complete output side sectioning for maintenance. Made with the “Make-Before-Break” configuration, it ensures manoeuvres without any micro-interruption of the power the load.
Emergency Line Stabilizer: under request, an emergency line voltage stabilizer can be added. In this case, the output voltage will be stabilized within ±2% even with inverter OFF
Parallel & Redundant: both UPS & Inverters may be made according to redundant configuration or with more paralleled systems.
Distribution: the systems can be provided with integral, or separated, load distribution avoiding a further external distribution panel.
INVERTER
Inveter
Thanks to a “made to measure” and with great design flexibility, the Inverter can be made to satisfy any plant requirement. It can be operated with D.C. input voltage from 24Vdc up to 600Vdc, with single phase or three phase output voltage according to the load topology, the output power and adapted to the D.C. voltage available in the Plant.
All of them are provided with output isolation transformer which increase the robustness permitting to operate in application having the earth completely isolated (IT systems) It can be provided with emergency line static switch, manual by-pass and/or voltage stabilizer.
CUSTOMIZATION
I nostri sistemi C.A. possono essere estremamente personalizzati, anche meccanicamente. Le carpenterie possono essere realizzate su misura con dimensioni, colore, apertura porte e grado di protezione IP a scelta; possono essere sezionati in più parti per facilitarne il trasporto e l’installazione; i componenti elettronici e gli interruttori possono rispettare una precisa vendor-list del Cliente, e molto altro ancora.
