Sensorless & programmable inverter line for brushless motors

Elettrotest  presents  a new  line of inverters for brushless motors with a sensorless algorithm, programmable performance  and high efficiency.

Thanks to a special phasing alghoritm inverters can control different types of motor (rare-earth elements or ferrite motors) and perform according to a wide parameter set  which is prorammable via Modbus.

Various types of control can be used:

• speed;

• power;

• current;

• flow;

• pressure.

Each control can be adapted to the dynamics of the application to obtain the best results in terms of comfort  and efficiency.

These models are particularly suited for ventilation applications (centrifugal blower, axial fan..) where dissipation elements  exploit air flux  for achieving maximum power dissipation.
All inverter are programmable and controllable with the same interface, so integration and model substitution is very easy.

o UVP (Under Voltage protection)

o OVP ( Over Voltage Protection)

o OTP (Over Temperature Protection)

o OCP (Over Current Protection);

• Current limitations (both peak and average) can be remotely set via software

• Overload up to two times nominal current until 3 seconds

• Dimensions 4U: 450:540

RPS are designed to satisfy even hard testing needs. If you properly set current limit, RPS becomes an excellent current generator for applications that required current control at high voltage (battery tests, led, etc. …).

You can also manage RPS easily by analog/digital interface using PLC systems.

RPS are high performance device. Below you can find the main technical features:

• Distortion of the output waveform <0.3%

• Stability of the output voltage <0.1%

• Accuracy of the output voltage <0.5%

• Recovery-time of the output waveform <10ms

• Recovery-time of the output voltage <10ms

• Compensated drop on wires ≤5% f.s

• Recovery-time of drop on wires <200ms

Rack Power supply - Space is no longer a problem!

Elettrotest launches the new 300 Vac / 300 Vdc  compact generator in order to satisfy even more the system integrators’ needs.
The RPS 1000 VA (Rack Power supply) will be followed by the 2500/5000/10000 VA models.

It is a voltage generator suitable for rack installations that occupies only 2 units and provides 1000 VA continous and 2000 VA  inrush.

The RPS 1000  is equipped with a programmable peak current control that makes it fit for applications (batteries, LEDs) that require limits on input current.

The RPS 1000 is a precise and stable generator like our top-end series. It is remotely controlled thanks to a serial connection or an isolated 0/10 V command, and it suits the most of the applications on the market.

Furthermore it has a series of digital commands that allow frequency changes, AC / DC voltage selections and remote control. At the same time it is characterised by digital inputs/outputs, which make the connection with PLC systems easy.

Elettrotest

Elettrotest S.p.A. was founded in 1986, thanks to the intuition of Professor Luigi Malesani at the University of Padua, who was collaborating with Rpm and had designed the first electric motor for them.
Rpm holds controlling interest in Elettrotest, which designs, builds and develops a wide range of controls for electric motors and professional electronic instruments.
The latter include instruments for measuring power and detecting the temperature in electric motor windings for programmable AC voltage generators. The controllers include electronic thermostats, phase-cutting voltage regulators, inverters for induction motors and high-efficiency brushless motors.
These are some of the most significant uses of the products designed, developed and built by Elettrotest, also based on customer specifications, since the company operates with maximum flexibility in order to compete in a global market, which it entered conquering new frontiers.
To keep design capacity levels high, Elettrotest continues to collaborate with the academic sector, following in the footsteps of Professor Luigi Malesani.
Elettrotest has more than fifty employees, half of whom (many with engineering degrees) work in the research, design and subsequent industrialisation of increasingly advanced products, which require constant attention to continuously evolving current legislation.

The designs are complex and derive from continuous updating, a result of careful attention to the market’s changing needs.

The stability of voltage and frequency: a necessity to guarantee our products

Elettrotest faces the market with new families of the classic TPS. The CPS series comes with the durability of the TPS series, as well as reliability and compactness, with high level performance for production departments and laboratory testing. The single-phase series has two models and the three-phase series has four models (5, 10, 20 and 40 KVA).
