Switch disconnectors
1000VDC ...................................................... 4
Excellent design features have allowed the rated operational
voltage upgrade of these switch disconnectors to 1000VDC in
DC21 class, a characteristic increasingly in demand for modern
photovoltaic systems.
Fuse holders and fuses
1000VDC ...................................................... 6
Fuse holders and fuses for the photovoltaic sector, designed to
protect strings with up to 32A current and 1000VDC operational
voltage rating.
Voltage and frequency
control relay .................................................. 7
A single voltage and frequency protection for single and three
phase cogeneration systems, also equipped with ROCOF (Rate
Of Change Of Frequency) function.
Contactors A range including three and four pole versions, up to 1600A in AC1 duty, with AC
and DC coil.
Measuring instruments Digital multimeters and power analyzers, expandable, with
graphic LCD, in addition to digital voltmeters, ammeters, wattmeters, frequency meters, power factor
meters form a complete range of measuring instruments for comprehensive control of the AC side of
a photovoltaic system (inverter output, delivery point and load connection).
Energy meters Single-phase types up to 63A, three-phase model with direct connection up
to 63A or by current transformer and a data concentrator. Among the best on the market also because
of the compact size, function expandability and a selection of monitored measurements. MID certified
versions, per EU Directive 2004/22/EC, also avalable.
Current transformers Ranging from 40A to 400A primiary current and 5A secondary;
solid and split core versions available.
Switching power supplies Suitable for single, two and three phase systems. 12V and
24V output, modular and DIN rail mount versions available.

General characteristics
The monitoring relay PMVF10 is designed and developed
to satisfy requirements of the local power authority
(ENEL guide edition 2.1 of 12/2010). The authority
imposes that the following automatic controls be done
whenever an independent power source (e.g. wind
turbine or photovoltaic systems, diesel generating set,
etc.) is connected in parallel with the electrical grid (local
low-voltage utility):
– Limits of minimum and maximum voltage values
– Limits of minimum and maximum frequency values
– Limit of the Rate Of Change Of Frequency (ROCOF).
When at least one of these limits are not respected,
abnormal conditions need to be signalled using a
contact.
Typically, the contact is used to isolate the independent
power source from the electrical grid.
The following protections are available:
– Maximum voltage
– Minimum voltage
– Maximum frequency
– Minimum frequency
– ROCOF.
TRMS (True-rms) measurements of this relay allow to
obtain a correct operation even in presence of harmonic
voltages.
The device has fixed tripping thresholds for minimum
and maximum voltage while those for frequency can be
selected between two predefined values using a rotary
switch. A reset delay is adjustable by potentiometer.
Operational characteristics
– Self powered by the system to control
– Compatible for:
• Three-phase systems (400VAC 50Hz), with or
without neutral
• Single-phase systems (230VAC 50Hz)
– TRMS measurements
– 2 relay outputs, each with one changeover contact,
rated 8A 250VAC in AC1
– Modular DIN 43880 housing (3 module)
– Degree of protection: IP40 on front (only when
mounted in housing or electric board with IP40);
IP20 on terminals.
PROTECTIONS
For maximum voltage:
– Threshold ≥ 1.13Ue (fixed)
– Tripping time ≤ 0.1s (fixed).
For minimum voltage:
– Threshold ≤ 0.825Ue (fixed)
– Tripping time ≤ 0.2s (fixed).
ADJUSTMENTS
“Mode”
Multifunction rotary switch:
• Control of phase or phase-to-phase
voltage values
• Frequency threshold ±0.3 or ±1Hz
• ROCOF (>0.5Hz/s) ON-OFF.
“Reset delay” Resetting time 0.1-30s.
STATUS INDICATIONS
– 1 green LED for system within limits (flashing when
out of limits)
– 3 red LEDs for minimum and maximum voltage,
minimum and maximum frequency and ROCOF.
Certifications and compliance
Certifications obtained: local power authority (ENEL
Guide, edition 2.1 10/2010).
Compliant with standards: IEC/EN 60255-5,
