LOVATO Electric has obtained MID certification for the single phase energy meters with 40A and 63A direct connection.
MID is the European Parliament directive, implemented in Italy since 2007 in relation to measuring instruments which undergo legal metrological control to satisfy requirements responding to reasons of public interest, public health, safety and order of the environment and the consumer, of levying taxes and duties and of fair trading.

LOVATO Electric presents the new voltage and frequency control relay PMVF10 for three-phase low-voltage systems, with or without neutral, and also compatible for single-phase low-voltage systems.
PMVF10 has been developed and designed to satisfy requirements of the local ENEL power authority guide, edition 2.1 (12/2010). The authority imposes that the following automatic controls be done whenever an independent power source (photovoltaic system, wind turbine, diesel generating set, …) is connected in parallel with the ENEL 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 ENEL electrical grid.
The following protections are available:
- Maximum voltage
- Minimum voltage
- Maximum frequency
- Minimum frequency
- ROCOF
TRMS (True rms) measurements of this relay allow 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.

QUESTION Which type of motor controls does the LOVATO Electric VFnC3 motor drive include? ANSWER VFnC3 can control motor driving in a number of ways and to select based on the exact application: •  Constant torque Motor torque is maintained at a constant value while motor speed changes. This setting is suitable when there are loads requiring the same torque at low and high speed levels, for instance conveyor belts or cranes. •  Variable torque Motor torque increases with motor speed. This setting is appropriate with loads such as pumps or fans which require torque value to be greater than speed increase. •  Sensorless vector control Motor torque is greater at low speed ranges. This function is useful when one needs a stable starting with smooth load operation when move up from low speed values and to avoid or eliminate load fluctuations caused by motor slippage (i.e. difference between drive and motor speeds). •  Energy-saving operation In this case and in all frequency (speed) ranges, the motor is driven by detecting load current and optimising the power flow that fits the load.
