EMi3-Servomotor Power Conditioner  5 kVA – 330 kVA

The EMi3 power conditioner series is a stabilizer, which due to its simplicity, reliability and robustness, has achieved to persist along the time, but with a re-designing, which has given technical improvements in electrical, electronic and mechanical.

The equipment can be used to stabilize the power supply of any kind of machine, which doesn’t require a regulation with a high response time, but it requires a constant and accurate stabilization, in particular, those ones tending to be complicated: high startup inrush currents, high reactive power, high powers,…etc.

The equipment makes a sensitive and efficient stabilization of the output voltage through its incorporated Booster transformer, Variac and microprocessor. To keep the output stable with a minimum tolerance, the servosystem uses a control of the DC motor by means of MOSFET transistors.

Main Features

• Wide range of powers for single and three phase installations.

• Toroidal autotransformers (Variacs) for all the power range, fast and efficient with DC motors of 12 V or 24 V.

• Output accuracy, better than 1 % (adjustable).

• Depending on the three-phase equipments model common and independent regulation per phase, they are immune to unbalanced loads.

• As standard, input voltage range of ±15 %, being able to manufacture ranges up to ±30 %.• High efficiency, up to 97,5 %.

• High response time, up to 70 V/sec.

• Complete control panel with LCD to supervise the stabilizer.

• Output accuracy guaranteed by a control with MOSFET servo.

• Immune to line voltage harmonics; True RMS stabilization.

• Stable operating against load and/or voltage fluctuations.

• Wide operating temperature ranges(–10 ºC.. +55 ºC).

• Dry contacts (2 as standard up to 11 as an option).

• Nil voltage harmonic re-injection.

• Optimized mechanical design, easy maintenance.

• Overload up to 200 % over the nominal for 20 sec..

• High robustness and reliability (high MTBF).

• Silent operating.

• Recyclable material in more than 80 %.
