EMC filter solutions for industrial applications like motor drives and machine tools. Furthermore, these types of filters are also suitable for mainframe computer systems, large uninterruptible power supplies, medical equipment, wind turbine power stations and a vast array of other threephase power electronics.

LCR's 3 Phase EMI filters (RFI filters, EMC filters) are typically used in Power Electronic products. These EMI filters attenuate mains-borne EMI generated back into the power line. LCR's 3 phase EMI filters also protect sensitive electronics and make them less susceptible to surges, Electrostatic Discharge (ESD) and other harmful voltage and current surges. Typical applications for these EMI filters (RFI filters, EMC filters) are in three-phase industrial drives, controllers, frequency converters and industrial machine tools.

JU Series Single-Phase Thyristor Regulators
The JU series small and lightweight thyristor regulators for single-phase loads are characterized with high panel installation density.
Two control systems, a phase-angle firing system and a zero-cross firing system, are built in and can be changed by remote contacts signal.

To control the temperature of electrical heating system using contactors and solid state relays is a simplest method of controlling. However, for heater load requiring gradual and smooth power regulation or for control using the step up or step down transformers, the thyristor power packs featured here are widely used. Incorporating the thyristors for heater power control, ensures steady control and enhances the life of the heaters. Single phase and three phase models are available for single phase load and three phase load in star or delta configurations. Special features allows facility to limit the voltage, current to the desired level and soft rise / fall of the voltage across the load at the desired rate. To suit OEM requirement, only SCR / Triac triggering cards can also be offered along with the wiring details to enable them to make their own thyristor power pack.
APPLICATIONS
For power control of electrically heated furnace, oven, chamber etc...

The MEW range of controllers are designed for regulating a three phase supply, using the phase-angle control principle. There are a number of versions available and choice depends upon the preferred method of control. The simplest units are used in conjunction with potentiometers or analog signals that provide the set point to give voltage, current or power regulation. Microprocessor control provides more functions for customising, through a digital front panel and also the ability to operate from standard field bus systems such as Interbus or Profibus.
