TRIFÁSICA 400V 50/60 HZ PROTECTION DEGREE IP21
Fittings: GC: range selector terminal block; V: digital voltmeter; L: pilot lamps; R: wheels
Note: models with different power, and/or different input range, and/or different output accuracy can be quoted on demand.
IREM voltage stabilisers are designed to deliver the declared power permanently (24/7) under the worst operating conditions, i.e. at full load, at minimum input voltage and max input current and at the declared ambient temperature.

IREM MODULAR SYSTEM
IREM 3PH voltage stabilisers (AVR) of higher power (from model Y326) are made in 3 sections in order to facilitate transport, handling, positioning and installation.
This kind of structure has been designed as a solution to problems related to handling of extremely big loads not common in electrical systems.
IREM voltage stabiliser modular system particularly helps during preparation of the site, avoiding the use of expensive lifting equipment and building of special openings to access the technical room.
The voltage stabiliser is made in separate sections corresponding to the single-phase units which will be connected to the plant.
No further interconnection between the different AVR sections is required, therefore the installation is perfectly similar to the connection of a voltage stabiliser made in one single cubicle.
Each single-phase unit includes all the control and regulation devices that determine its autonomous and independent operation.
In the unlikely event of a failure, this type of design limits the fault propagation, ensuring the best functionality and allows to act in a targeted and selective way on the component without having to operate on the other sections.
In this case the solution allows to contain the periodic maintenance and repair costs.
HIGHLIGHTS
REDUCED SHIPPING COSTS
Smart solution to problems related to handling/shipping of bulky loads.
REDUCED MAINTENANCE COSTS
Easy intervention on one section ensuring the functionality of the other units.
EASIER HANDLING
Excellent solution avoiding the use of expensive lifting equipment and building of special openings to access the installation room.
